Hybrid composite materials are more attracted by the engineers because of their properties like stiffness and high specific strength which leads to the potential application in the area of aerospace, marine and automobile sectors. In the present investigation, the flexural strength and flexural modulus of carbon and glass fibers reinforced epoxy hybrid composites were studied. The vacuum bagging technique was adopted for the fabrication of polymer hybrid composite materials. The hardness, flexural strength and flexural modulus of the hybrid composites were determined as per ASTM standards. The hardness, flexural strength and flexural modulus were improved as the fiber reinforcement contents increased in the epoxy matrix material.
Effect of stacking sequence and hybridization on the tensile and flexural properties of composite
laminates between basalt, jute and flax with E-glass reinforced epoxy have been investigated experimentally. It
was found that stacking sequence is not highly significant on tensile properties, contrasting with flexural strength
and modulus which were strongly dependent on the hybrid configuration between sandwich-like (SL) and
intercalation (IC) sequences. Specific modulus based on the variation densities of the hybrid laminates was used
to discover the best combination either basalt, jute or flax with E-glass exhibits superior properties concerning
on the strength to weight- ratio. Hence, stacking sequences and material selection are among predominant factors
that influence on mechanical properties and very crucial in designing composite hybrid system to meet the desired
requirements.

A Study on Concrete Using Bottom Ash, Manufacturing Sand and Hybrid Steel and...IOSR Journals
This study in concrete is to study about hybrid combination of fibers such as corrugated steel and coir on the mechanical properties and concrete. From the compressive strength test and split tensile test carried out on 3Nos of cube and cylinder for each trial, it was observed that compared to control mix, compressive strength increases. The increase may be due to increased availability of fibers at the micro-cracks, increase in pull out strength due to bending and warpness of fibers and improvement in bond between fiber and matrix at the interface. The presence of steel fibers in hybrid combination with coir fiber has improved post-cracking behavior of the beam specimens
Abstract In the last decades the composites have been widely used in the construction, automobile and aerospace industries. Among them,
Natural fiber composites are emerging as low cost, lightweight and superior alternatives to synthetic fiber composites. This study

Jute and hollow conjugated polyester fiber (HCP)-reinforced nonwoven composites were designed by Box and Behnken model approach. Its thermal properties such as thermal conductivity, thermal resistance, thermal transmittance, and thermal diffusivity were evaluated. From the test results of response surface method (RSM), the weight of composite material maintained as 3280 g/m2 with the proportion of jute/HCP fiber in the ratio of 50/50%, 60/40%, and 70/30% played a significant role in insulation and mechanical properties. Various needling density maintained on the
composite material such as 300, 150, and 75 punches/cm2 contributes to the role of significant impacts on the research process. The optimum of 150 needling density with the proportion of 50/50 Jute and HCP fiber was
selected to produce four kinds of composite structures. Its thermal,
sound, electrical insulation values and limiting oxygen values were analyzed and suggested for building environments

Composites fiber are moving into the crucial stream of the automobile industry, with
manufacturers and suppliers finding different blends of bio composites, glass fibers and places to use
them. It has been observed that natural fibers such as flax, hemp, kneaf, jute and sisal help reducing in
weight, cost, and CO2, less dependence on other oil sources, and reusability. Also Fibers like flax, hemp
or jute are cheap, have better stiffness per unit weight, corrosion resistance, electrical insulation,
reduction in tooling and assembly costs, low thermal expansion, higher stiffness and strength, fatigue
resistance and have a lower impact on the environment. [1]
The present study/research focuses on exploring the possibility of using jute fiber, E-Glass and
embedding these in a biopolymer matrix system – epoxy – the task of which is to hold the fibers
together. This epoxy stabilizes the shape of the composite structure, transmits the shear forces between
the mechanically high-quality fibers, and protects them against radiation and other aggressive media.
The component is conditioned and prepared for testing and subjected to tensile, compression, hardness
and bending test calculating the element results with ANSYS by using the test results. Promising results
have been observed and this study enables for future study in the field of natural fiber composite
materials. Main aim of this paper is to reduce the impact on the environment, by using recyclable
natural fibers[6] [7].

Analysis of Multicast Routing Protocols: Puma and OdmrpIJMER
ABSTRACT: In general, Wireless communication is defined as sharing of information between one or more systems
through wireless links. Wireless networks can be categorized into two different modes as infrastructure based and
infrastructure less. Infrastructure based mode is the most common use wireless mode for the end user loop. Infrastructure
fewer modes also called as the Ad hoc mode relies on wireless communications without any fixed infrastructure.
Infrastructure based networks are characterized by their use of access points (AP), or base stations. The most known
example of infrastructure based wireless network is GSM and more recently, Wi-Fi. Ad Hoc networks introduce a new way
of communication. An ad hoc network is a collection of wireless mobile nodes that dynamically functions as a network
without the use of any existing infrastructure and centralized administration. Mobile Ad-hoc networking (MANET), an
emerging field of wireless networking is an autonomous system of wireless mobile hosts, connected by wireless links that
dynamically create a temporary network and establish an infrastructure less network. The topology of the network may
change frequently and unpredictably. Multicast routing has been widely applied in mobile ad hoc networks (MANETs), to
support different group oriented applications like video conferencing, interactions with Special interest groups etc.,
efficiently. This paper presents the comparative analysis of two multicast routing protocols, PUMA and ODMRP.

Orientation Effects of Stress Concentrators on the Material Deformation Behav...IJMER
Present investigation pertains to carry out to experimental work to generate data in order to
establish the mode of material deformation and fracture in AISI 316 stainless steel strips of 1.70mm thickness in
the presence of elliptical notches at the center of the specimen whose major axis were designed to incline to the
tensile axis at an angle of 0o
, 45o
and 90o
and the same happens to be the axis of rolling. An elliptical hole of
8.00mm (major axis) with 5.0mm (minor axis) were machined in each specimen so as to correspond to the above
angles of 0o
45o
and90o
and one specimen without any elliptical hole as a notch for comparative analysis of the
experimental data. These flat specimens with and without stress concentrators were tested under tension using
Hounsfield Tcnsomctcr and the changes in notch geometry have been recorded at various loadings. Further, the
visual appearance of the cracks initiation have been continuously observed and recorded. The effect of stress
ratio factors and the strain ratio parameters on the mode of fracture on material deformation in and around the
stress concentrator has been thoroughly analyzed and it has been established that the crack initiation began
either at the inner tips of the minor or the major axis of the elliptical stress concentrator, but, always
perpendicular to the direction of loading irrespective of the rolling direction and the orientations of the stress
concentrators. However, the changes in the rotation of the major and the minor axis of the elliptical stress
concentrators were found to alter, and, this alteration in fact assisted in estimating the strains along the major as
well as the minor axis of the stress concentrators. Relation between a plastic strain ratio with respect to the ratio
between the major and the minor strains was observed to be of extremely complex nature. The overall
observation in the present investigation has indicated that thin strips or sheet specimens containing a single or
multiple or a combined type of stress concentrators will create a keen interest in the research approach of the
investigators and make them aware of the seriousness of the presence of the stress concentrators and caution
them to incorporate any possible design notifications in order to avoid any catastrophic failure (s).
Evaluation of Compressive Strength and Water Absorption of Styrene Butadiene...IJMER
In this research, effect of Styrene-Butadiene Rubber (SBR) latex on water absorption and
compressive strength of concrete has been studied. A locally available “RIPSTAR-148” is used as SBR
Latex.
It has been observed that SBR latex improves the internal structure of the latex modified
concrete resulting in considerable reduction in the water absorption value at 28 days of age. However,
at early age, the effect of SBR latex on water absorption is adverse. Same trend is noticed for the
compressive strength; at 7 days of age, SBR latex has negative effect while at 28 days, the addition of
SBR latex in concrete results in enhancement of compressive strength. Based on the results of this
study, latex modified concrete made using “RIPSTAR-148” may be recommended to be used in RC
structures in INDIA. However, for the mixes rich in cement, the dosage of “RIPSTAR-148” needs to be
adjusted to maintain required workability of concrete.
Performance of MMSE Denoise Signal Using LS-MMSE TechniqueIJMER
This paper presents performance of mmse denoises signal using consistent cycle spinning
(ccs) and least square (LS) techniques. In the past decade, TV denoise technique is used to reduced the
noisy signal. The main drawback is the low quality signal and high MMSE signal. Presently, we
proposed the CCS-MMSE and LS-MMSE technique .The CCS-MMSE technique consists of two steps.
They are wavelet based denoise and consistent cycle spinning. The wavelet denoise is powerful
decorrelating effect on many signal domains. The consistent cycle spinning is used to estimation the
MMSE in the signal domain. The LS-MMSE is better estimation of MMSE signal domain compare to
CCS-MMSE.The experimental result shows the average MMSE reduction using various techniques.

with built in, two servo motor drivers, data input/output, and micro processor modules. Other
components of the tracking hardware are, servo motors actuators and four LDR light intensity sensors. A
feedback control soft ware program, designed and constructed in the present work, enables the solar
tracker to automatically compensate for the sun location’s change to enhance the PV cells efficiency. The
LDR sensors are employed to continuously detect the sun rays intensity at four, light exposed isolated
positions, representing up-right, up-left, down-right, and down-left sides of the solar panel. LDRs data is
hence sent to the control software. The data is used to decide proper actuation actions and send them to
the servomotors to redirect the PV cells panel perpendicular to incident sun rays. Sensors and actuation
signals are exchanged via the in/out data module of the Arduino package. Results of the present
experimental work show that using the present tracking system increases the PV cell out power by about
38% compared with that of a fixed collector

Repairing of Concrete by Using Polymer-Mortar CompositesIJMER
Replacement of concrete buildings, bridges, roadways and other structures is becoming
more and more expensive as costs of materials and labor continue their upward spiral. Polymermodified or polymer cement mortar (PCM) and concrete (PCC) are a category of concrete-polymer composites which are made from cement mortar or concrete with polymers, The main application of polymer cements is in concrete repair. In this research two sets of mixtures were prepared that consist
of mortar and polymer to fabricate the polymer-cement composite. The first set include mortar with
ratio (1:1) (cement-sand) without water, while the other set include mortar with ratio (1:2) (cementsand)
without water. The polymer was Quickmast105 epoxy which is added to the mortar after mixing
the resin with the hardener in proportion of (1:3). Each set was consist of different percentage of polymer (50:50, 40:60 and 30:70). Tests were conducted, including compression, flexural and bonding strength, were several results obtained including, the highest compressive strength was about 102.889MPa and the highest value of flexural strength was about 57.648MPa for (1:1), the polymermortar with 40:60 ratio showed a higher bonding compressive strength. Proportionality between the
cement and sand and also between the polymer and mortar plays a major role in adhesion and strength are considered key factors in the bonding and portability to repairs.
Data and Information Integration: Information ExtractionIJMER

Greedy – based Heuristic for OSC problems in Wireless Sensor NetworksIJMER
This paper contains optimize set coverage problem in wireless sensor networks with adaptable sensing range. Communication and sensing consume energy, so efficient power management can extended the network lifetime. In this paper we consider a enormous number of sensors with adaptable sensing range that are randomly positioned to monitor a number of targets. Every single target may be redundantly covered by various sensors. For preserving energy resources we organize sensors in sets stimulated successively. In this paper we introduce the Optimize Set Coverage (OSC) problem that has in unbiased finding with an extreme number of set covers in which every sensor node to be activated is connected to the base station. A sensor can be participated in various sensor sets, but the overall energy consumed in all groups is forced by the primary energy reserves. We show that the OSC problem is NP-complete and we propose the solutions: an integer programming for OSC problem, a linear programming for OSC problem with greedy approach, and a distributed and localized heuristic. Simulation results are presented and validated to our approaches.
Properties of ‘Emu’ Feather Fiber CompositesIJERA Editor
A composite is usually made up of at least two materials out of which one is binding material called matrix and the other is a reinforcement material known as fiber. Many researchers are focusing on natural fiber composites. But, in the present work, composites were prepared with epoxy (Araldite LY-556) resin and „emu‟ bird feathers as fiber. The composites were prepared by varying the weight percentage (P) of „emu‟ fiber ranging from 1 to 5 and length (L) of feather fibers from 1 to 5 cm. The composite specimens were prepared and cured as per ASTM standards. Studies were carried out on various properties like mechanical properties, Thermal properties and Effect of atmosphere, Soil and certain Chemicals. An attempt is made to model the mechanical properties through response surface methodology (RSM). Analysis of Variance (ANOVA) is used to check the validity of the model. The results reveal that the developed models are suitable for prediction of mechanical properties of Epoxy „Emu‟ Feather Fiber Composites.

Composites are engineered materials made from two or more constituents with different physical or chemical
properties, which remain separate and distinct within the finished structure. A fiber is a material, which is made into
a long filament with diameter generally in the order of 10 microns. The aspect ratio of length to diameter can be
ranging from thousands to infinity in continuous fibers. Increasing worldwide environmental awareness is
encouraging scientific research into the development of cheaper, more environmentally friendly and more
sustainable construction and packing materials. For environment concern on synthetic fiber (such as glass, carbon,
ceramic gibers etc) natural fibers (such as flax, hemp, jute, kenai) etc are widely used. Industrial hemp fiber is one
of the strongest of the natural fibers available and possesses benefits such as low cost and low production energy
requirements. The primary objective of this research is to fabricate the natural fiber composites with suitable
processing/manufacturing methods and to examine the mechanical properties when subjected to Tension, Bending
and to compare & contrast the results with the available literature. In this research work, hemp fiber reinforced
Epoxy matrix composites have been developed by hand layup method with varying process parameters, such as
coupling agent(with and without compatibilizers) and different fiber percentages (10%,20% and 30% by weight).
The developed composites were then characterized by tensile test and flexural testing. Results show that the tensile
strength and flexural properties increases with the increase in fiber percentage. However after a certain percentage
the tensile strength decreases again. Compared to untreated hemp fiber, no significant changes in the tensile strength
have been observed for treated hemp fiber reinforcement. The flexural strength / modulus of the composite were
higher compared to pure epoxy for all filler/fiber loadings.

Geochemistry and Genesis of Kammatturu Iron Ores of Devagiri Formation, Sandu...IJMER
The Greenstone belts of Karnataka are enriched in BIFs in Dharwar craton, where Iron
formations are confined to the basin shelf, clearly separated from the deeper-water iron formation that
accumulated at the basin margin and flanking the marine basin. Geochemical data procured in terms of
major, trace and REE are plotted in various diagrams to interpret the genesis of BIFs. Al2O3, Fe2O3 (T),
TiO2, CaO, and SiO2 abundances and ratios show a wide variation. Ni, Co, Zr, Sc, V, Rb, Sr, U, Th,
ΣREE, La, Ce and Eu anomalies and their binary relationships indicate that wherever the terrigenous
component has increased, the concentration of elements of felsic such as Zr and Hf has gone up. Elevated
concentrations of Ni, Co and Sc are contributed by chlorite and other components characteristic of basic
volcanic debris. The data suggest that these formations were generated by chemical and clastic
sedimentary processes on a shallow shelf. During transgression, chemical precipitation took place at the
sediment-water interface, whereas at the time of regression. Iron ore formed with sedimentary structures
and textures in Kammatturu area, in a setting where the water column was oxygenated.

Non linear analysis of Robot Gun Support Structure using Equivalent Dynamic A...IJMER
Robot guns are being increasingly employed in automotive manufacturing to replace
risky jobs and also to increase productivity. Using a single robot for a single operation proves to be
expensive. Hence for cost optimization, multiple guns are mounted on a single robot and multiple
operations are performed. Robot Gun structure is an efficient way in which multiple welds can be done
simultaneously. However mounting several weld guns on a single structure induces a variety of
dynamic loads, especially during movement of the robot arm as it maneuvers to reach the weld
locations. The primary idea employed in this paper, is to model those dynamic loads as equivalent G
force loads in FEA. This approach will be on the conservative side, and will be saving time and
subsequently cost efficient. The approach of the paper is towards creating a standard operating
procedure when it comes to analysis of such structures, with emphasis on deploying various technical
aspects of FEA such as Non Linear Geometry, Multipoint Constraint Contact Algorithm, Multizone
meshing .

question is whether digital computers can or ever will process natural languages. We have tried to
explore in depth and break down the types of ambiguities persistent throughout the natural languages
and provide an answer to the question “How it affects the machine translation process and thereby
machine learning as whole?” .

the help of Likert scale we define a rule based model and delegate some mass score to every process and
develop one tool name as MuxSet which will help the software developers to select an appropriate
development process that may enhance the probability of system success.
Material Parameter and Effect of Thermal Load on Functionally Graded CylindersIJMER
The present study investigates the creep in a thick-walled composite cylinders made
up of aluminum/aluminum alloy matrix and reinforced with silicon carbide particles. The distribution
of SiCp is assumed to be either uniform or decreasing linearly from the inner to the outer radius of
the cylinder. The creep behavior of the cylinder has been described by threshold stress based creep
law with a stress exponent of 5. The composite cylinders are subjected to internal pressure which is
applied gradually and steady state condition of stress is assumed. The creep parameters required to
be used in creep law, are extracted by conducting regression analysis on the available experimental
results. The mathematical models have been developed to describe steady state creep in the composite
cylinder by using von-Mises criterion. Regression analysis is used to obtain the creep parameters
required in the study. The basic equilibrium equation of the cylinder and other constitutive equations
have been solved to obtain creep stresses in the cylinder. The effect of varying particle size, particle
content and temperature on the stresses in the composite cylinder has been analyzed. The study
revealed that the stress distributions in the cylinder do not vary significantly for various combinations
of particle size, particle content and operating temperature except for slight variation observed for
varying particle content. Functionally Graded Materials (FGMs) emerged and led to the development
of superior heat resistant materials.

I. Introduction
Composites
A typical composite material is a system of materials composing of two or more materials (mixed and
bonded) on a macroscopic scale. Van Suchetclan [5] explains composite materials as heterogeneous materials
consisting of two or more solid phases, which are in intimate contact with each other on a microscopic scale.
They can be also considered as homogeneous materials on a microscopic scale in the sense that any portion of it
will have the same physical property.
Classification of composites
a) Metal Matrix Composites (MMC)
b) Ceramic Matrix Composites (CMC)
c) Polymer Matrix Composites (PMC)
Maize husk (MH) is one of the major agricultural residues produced as a by-product during maize processing.
Usually it has been a problem for maize farmers due to its resistance to decomposition in the ground, difficult
digestion and low nutritional value for animals. According to researches the lignin and hemicelluloses contents
of maize husk are lower than wood whereas the cellulose content is similar. For this reason MHF can be
processed at higher temperatures than wood. Therefore, the use of maize husk in the manufacturing of polymer
composites is attracting much attention.
II. Literature Review
Particulate filled polymer composites have been used extensively in various fields due to their low
production costs and the ease of manufacturing. Besides, they behave isotropically and are not as sensitive as
long fiber composites to the mismatch of thermal expansion between the matrix and the reinforcement [6-9].
The mechanical properties of particulate filled polymer composites depend strongly on the particle size,
particle-matrix interface adhesion and particle loading. Smaller particle size yields higher fracture toughness for
calcium carbonate filled high density polyethylene (HDPE) [10-12]. Many research articles have been published
to justify the utility and to establish advantageous features of such natural fibers [17]. Natural fibers under
investigation include flax, hemp, jute, sisal, kenaf, coir, kapok, banana, henequen and many others [18]. The
various advantages of natural fibers over man-made glass and carbon fibers are reported to be low cost, low
Abstract: Amids the growing concern on environmental issues, science is seeking various alternatives
to replace the synthetic and non degradable fibers composites with environment friendly
biocomposites of comparable characteristics and performance. Visualizing the importance of polymer
composites and owing to issue of ecological concerns, this experiment is an attempt to further
investigate possibility of bio composites (Particularly maize husk) as an alternative of available
synthetic polymer composites. Taking one leap forward the experiment also approximate qualities the
effect of individual parameters on erosion by the application of Taguchi Technique. Experimental
system were devised and designed to study the erosion rate of maize husk fiber Reinforced Polymer
composites at various impingement angles, with profound variables such as particle velocity, fiber
content, and particle size (erodent size) To cast the composite epoxy Resin LY 556 with corresponding
hardener HY 551 was used. The erodent size was in range of it irregular shape. The tribological
performance of sheets was investigated in respect to set of various variable parameters as suggested
by L16 series of Taguchi Techniques. The morphological feature before and after the experiments
were studies using SEM.
Keywords: Biocomposites, erosive wear rate, brittle fracture Taguchi Technique, impingement angle,
erodent size.

density, comparable specific tensile properties, non-abrasive nature, non-allergic to the skin, reduced energy
consumption, less health risk, renewability, recyclability and bio-degradability [19-21].
Maize husk which has become environmentally problematic waste is now being converted into useful industrial
materials [22]. Maize stalk has therefore demonstrated its potential to be used to reinforce natural rubber for
shoe sole production [23]. In the present work, the maize husk has been taken as a particulate filler and epoxy as
matrix to prepare a bio-composite, and finding the various properties.
III. Methodology
Matrix materials are of different types like metals, ceramics and polymers. Polymer matrices are most
commonly used because of cost efficiency, ease of fabricating complex parts with less tooling cost and they also
have excellent room temperature properties when compared to metal and ceramic matrices. In the present
research work, maize husk (collected from Rajaram Maize product, Rajnandgaon,C.G.,India) is used as filler
material polymer matrix composites.

2. Mechanical characterization
2.1 Tensile test
The standard test method according to ASTM D3039-76 has been used; gauge length of the test specimen
used is 50 mm. The tensile test has been performed in universal testing machine INSTRON H10KS .The test
was conducted with a cross head speed of 5mm/min. For each test, composite of three samples were tested and

Where, “σ” is tensile strength, “P” is the load applied, “A” is the cross sectional area, “E” is Young‟s modulus,

2.2 Flexural strength.
Three point bend test was carried out in an UTM 201 machine in accordance with ASTM D2344-84 to
measure the flexural strength of the composites. The loading arrangement for the specimen and the photograph
of the machine used .All the specimens (composites) were of rectangular shape having length varied from 100-
110 mm, breadth of 50-60 mm and thickness of 2.5-3.5 mm. A span of 100 mm was employed maintaining a
cross head speed of 5mm/min. The flexural strength in a three point bending test is found out by using equation

Where, „b‟ is breadth, „t‟ is thickness and „y‟ is extension of the specimen during experiment.
3. Micro-hardness measurement
Micro-hardness measurement is done using a Leitz micro-hardness tester. A diamond indenter, in the form
of a right pyramid with a square base and an angle 1360 between opposite faces, is forced into the material
under a load F. The two diagonals X and Y of the indentation left on the surface of the material after removal of
the load are measured and their arithmetic mean L is calculated. In the present study, the load considered is F =
0.245 N and Vickers hardness number is calculated using the following equation.

4. Scanning electron microscopy
The surfaces of the maize husk filled epoxy composites are examined by JEOL JSM-6480LV . The
specimens are cleaned thoroughly, air dried before being observed under SEM at 20 kV. The composite samples
are mounted on stubs with silver paste. To enhance the conductivity of the samples, a thin film (100 Å
thicknesses) of platinum is coated onto them in JEOL sputter ion coater before the photomicrographs are taken.
5. Tribological characterization
5.1 Solid particle erosion test
The set up for the solid particle erosion wear test used in this study is capable of creating reproducible
erosive situations for assessing erosion wear resistance of the prepared composite samples. The test rig consists
of an air compressor, an air drying unit, a particle feeder and an air particle mixing and accelerating chamber. In
the present study, dry silica sand of four different mean particle sizes (40μm, 60μm, 80 μm and 100μm) are
used as erodent.
5.2 Taguchi experimental design
From a scientific viewpoint, these experiments are either one or a series of tests to either confirm a
hypothesis or to understand a process in further detail. In order to achieve a meaningful end result, several
experiments are usually carried out. The experimenter needs to know the factors involved, the range these
factors are varied between, the levels assigned to each factor as well as a method to calculate and quantify the
response of each factor. This one-factor-at-a-time approach will provide the most favorable level for each factor
but not the optimum combination of all the interacting factors involved. Thus, experimentation in this scenario
can be considered as an iterative process. Although it will provide a result, such methods are neither time nor
cost effective. But the design-of-experiments (DOE) is a scientific approach to effectively plan and perform

experiments using statistics. In such designs, the combination of each factor at every level is studied to
determine the combination that would yield the best result.

The impact of these four parameters on the erosion wear rate of these maize husk filled epoxy composites is
therefore studied in this work using Taguchi‟s L16 orthogonal array design. The control factors and the
parameter settings for erosion test are given in Table 2. and Table 3 presents the selected levels for various
control factors. The tests are conducted as per the L16 experimental design given in Table 4.
The experimental observations are further transformed into signal-to-noise (S/N) ratios. There are several S/N
ratios available depending on the type of characteristics as given by following equations:
„Smaller- the- better‟ characteristic: 21

Where, „n‟ is the number of observations and „y‟ is the observed data. The S/N ratio for minimum wear rate
(both for erosion as well as sliding) comes under „smaller is better‟ characteristic, which can be calculated as
logarithmic transformation of the loss function by using Equation (7).

2.3 Micro-hardness
Hardness of is considered as one of the important factor which governs the wear resistance of any material.
In the present investigation, micro-hardness values of the epoxy composites with maize husk filled in different
proportions have been measured and the variation of micro-hardness with the maize husk content in the
composites is shown in Figure 9.

2.4 Morphological Behaviour
It is clear from the image that the maize husk particles are not of regular shape and similar size which is
obvious because the particle used in present investigation are generated by grinding process and no grinding
process is as accurate to develop particles of similar shape and size.

4. Erosion wear and Taguchi analysis
Table 6. shows the solid particle erosion wear rates of maize husk filled epoxy composites under various
test conditions. The weight of the composite is taken before the erosion test, later after the erosion test again the
weight of the composite under study is taken and the difference in their weight is calculated. The weight of the
composite after erosion is always less than that of before erosion. The difference in their weight is called mass
or weight loss of the sample due to solid particle impact. The ratio of this mass loss to the mass of the eroding
particles causing the loss is then computed as the erosion rate. The erosion rate is thus defined as the mass loss
of the specimen due to erosion divided by the mass of the erodent causing the loss.

The analysis is made using the popular software specifically used for design of experiment applications known
as MINITAB 14.
This present investigation on particulate filled maize husk/ epoxy composites has led to the following
conclusions:
1) Maize husk possesses reinforcing potential to be used as a filler material in polymer matrix composites.
2) Successful fabrication of epoxy matrix composites reinforced with maize husk particles is possible by
simple hand-lay-up technique.
3) The density of the fabricated composites decreases with increase in weight fraction and it also possesses
low void content; even it is prepared by hand lay-up technique.
4) The tensile strength and flexural strength of these composites decreases with filler content because of poor
mechanical properties of maize husk.
5) By surface morphology it is clear that there is good adhesion between the matrix phase and filler phase and
very less gap is visible between them which results in low amount of porosity.
6) The micro-hardness of this natural filler based composite increases invariably with filler loading and
provides improved impact resistance.
7) This study reveals that maize husk possesses good filler characteristics as it improves the erosion wear
resistance of the epoxy resin.
8) Erosion characteristics of these composites can also be successfully analysed using Taguchi experimental
design scheme. Taguchi method provides a simple, systematic and efficient methodology for the
optimization of the control factors.
