Evaluation of mechanical and water absorption behaviour of coir and rice husk...eSAT Journals
The document evaluates the mechanical and water absorption behavior of composites reinforced with coconut coir fiber and rice husk powder. Composites were prepared with untreated and NaOH-treated coir fiber at different weight fractions (5%, 10%, 15%) combined with epoxy resin and rice husk powder. Mechanical tests for impact strength and hardness were conducted according to ASTM standards. Results showed untreated composites had higher impact strength and hardness than treated composites due to better fiber-matrix bonding. However, treated composites absorbed less water than untreated composites due to the hydrophobic nature of chemically-modified fiber. In conclusion, untreated composites performed better mechanically while treated composites were more resistant to water absorption.

Mechanical Behaviour of Agricultural Residue Reinforced CompositesScientific Review SR
The increasing awareness and the quest for newer materials have given renewed interest to the
development of green composites. This article focuses on the potential use of abundantly available waste
agricultural residue for the preparation of composites. The mechanical properties of Rice straw fibers reinforced
with Polyester resin, Vinyl ester resin and Isophthalic polyester resin are studied and compared. Hand Layup
technique is used to prepare the samples on which flexural and impact studies are made. Samples are made using
different volumetric compositions of fiber and resin. The results show that the Vinyl ester resin and Isophthalic
resin offer good mechanical properties when compared to the polyester resin. Both these resins show similar
behavior with respect fiber loading. The flexural strength decreases with increasing fiber loading for polyester
resin and increasing trend is observed for both vinyl ester and isophthalic resin. Impact strength increases for the
increase in fiber loading up to a certain limit and then decreases. It can be concluded from this study that the
agro-waste materials are attractive reinforcements from the standpoint of their mechanical properties.

A Study on the Effective Teaching Learning Process in English Curriculum at t...ijtsrd
“One Language sets you in a corridor for life. Two languages open every door along the way” Frank Smith English as a foreign language or as a second language has been ruling in India since the period of Lord Macaulay. But the question is how much we teach or learn English properly in our culture. Is there any scope to use English as a language rather than a subject How much we learn or teach English without any interference of mother language specially in the classroom teaching learning scenario in West Bengal By considering all these issues the researcher has attempted in this article to focus on the effective teaching learning process comparing to other traditional strategies in the field of English curriculum at the secondary level to investigate whether they fulfill the present teaching learning requirements or not by examining the validity of the present curriculum of English. The purpose of this study is to focus on the effectiveness of the systematic, scientific, sequential and logical transaction of the course between the teachers and the learners in the perspective of the 5Es programme that is engage, explore, explain, extend and evaluate.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

Design Simulation and Hardware Construction of an Arduino Microcontroller Bas...ijtsrd
This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

Physical Properties of Hemp
POLYESTER RESIN
Polyester resins are the most economical resinsystemsused
in engineering applications, but with limited use in high
performance composites. They can be produced for a large
variety of properties, from soft and ductile to hard and
brittle. The principal advantages of polyesters are: low cost,
low viscosity, and a relatively short curing period. Polyester
resins can be formulated to cure at either room or elevated
temperatures.
Mechanical Properties of Polyester (Unsaturated
polyester Resin properties)
ACCELERATOR
Cobalt octoate is generally used as accelerator for polyester
resins. Curing Unsaturated Polyester resins at room
temperature cannot be effected by an organic peroxideonly,
an accelerator should be added as well. In most cases cobalt
octoates are preferred, as theycanbeappliedincombination
with a wide range of peroxides and besides, becauseofsome
specific properties, viz:
By varying the quantity of cobalt octoate, the reaction
speed can be rather well adapted to the working
circumstances.
The pot life of the polyester resin is hardlyinfluencedby
the addition of cobalt accelerator.
Cobalt accelerators have a rather small influence on the
resin color. The resin is not discolored by U.Vlight.
Cobalt accelerators make a resin less sensitive to air
inhibition.
It should be taken into consideration, however, that
pigments and fillers easily absorb cobalt accelerators
and render them inactive.
A dosage of minimum 0.3% is necessary to get on
efficient cure reaction at room temperature. Also at
elevated temperatures small amounts of cobalt
accelerator are used to speed up the reaction
(corrugated sheeting, filament winding).
Cobalt Octoate
CATALYST
M.E.K.P (methyl ethyl ketone peroxide) is colorless organic
peroxide used to catalyze Polyester Resins and Gelcoats.
When M.E.K.P. is mixed with polyester based resins or
Gelcoats, the resulting chemical reactioncausesheattobuild
up and cure or harden the resin.
Our polyester resins are used with an M.E.K.P. catalyst at a
2% ratio based on volume. However, extra M.E.K.P catalyst
maybe required in cooler temperatures or if faster drying
times is desirable.
MEKP is a highly toxic clear liquid. It is a strong oxidizing
agent and a corrosive. Acute and chronic toxicity can occur
as an occupational hazard. MEKP catalyst should be used
carefully used and stored.
MOULD RELEASING AGENT (WAX)
Composite parts are generally made in a female mold. The
wax would be applied to a prepared mold surface and then
backed with layers of reinforcement and additional resin.
When the part is removed from the mold, this wax surface

would be the exterior surface of the part and it is acted as
mould releasing agent. In our case in the preparation of
specimen the top surface is also closed with OHP sheet
which is coated with wax in order to attain smooth surface.
GLASSMOULD
Moulds can be made from a wide variety of materials and in
a number of ways but moulds for composites need to be
compatible with the resin system and curing. We used glass
mould for making the composite specimen and its
measurements are
Length=200mm, Width=200mm, Depth = 3mm
GLASSMOULD
HANDROLLER
Hand roller is used with Natural or synthetic fiber,andother
woven reinforcements, they help significantlyineliminating
small air bubbles and pin- holes, which very often cause a
'glitter' effect .
They are also useful to roll the wet composite to ensure an
enhanced interaction between the reinforcement and the
matrix, to facilitate a uniform resin distribution, and to
obtain the required thickness of the composite.
Hand Rolling Process
COMPOSITION OFCOMPOSITE
FIBER VOLUMEFRACTION
Fiber volume ratio is an important mathematical element in
composite engineering. Fiber volume ratio, or fiber volume
fraction, is the percentage of fiber volume in the entire
volume of a fiber-reinforced composite material. When
manufacturing polymer composites, fibers are impregnated
with resin. The amount of resin to fiber ratio is calculated by
the geometric organization of the fibers, which affects the
amount of resin that can enter the composite. The
impregnation around the fibers is highly dependent on the
orientation of the fibers and the architecture of the fibers.
The geometric analysis of the composite can be seen in the
cross-section of the composite. Voids are often formed in a
composite structure throughout the manufacturing process
and must be calculated into the total fiber volume fraction of
the composite. The fraction of fiber reinforcement is very
important in determining the overall mechanical properties
of a composite. A higher fiber volume fraction typically
results in better mechanical properties of the composite.
The amount of fiber in a fiber reinforced composite directly
corresponds with the mechanical properties of the
composite.
1. Adding too little fiber reinforcement in the composite
will actually deteriorate the properties of the material.
2. Too much fiber volume may also decrease the strength
of the composite due to the lack of space for the matrix
to fully surround and bond with the fibers.
FIBER WEIGHT FRACTION
Fiber weight fraction or fiber weight ratio is similar to fiber
volume fraction, but instead of total volume of composite,
total weight of composite is considered and here ratio is
between the weight of fiber to the weight of the matrix or
resin.

Hand layup process
Hand lay-up, which is the most common and widely used
open mould composite manufacturing process. Initially, a
thin layer of anti adhesive coat (wax) is applied on the glass
mould for easy extraction. Then small amount of the
polyester resin is poured or applied using a brush in the
mould and the prepared fibers are placed in theglassmould.
The remaining resin is applied on the fibers and a roller is
used to force the resin into the composites .Here making

HYBRID COMPOSITES
Hybrid composite is generally used to describe a matrix
containing at least two types of reinforcements, but this
report is restricted to hybrid composites containing two
types of reinforcing fibers. Such composites are also called

focuses on polymer matrix composites, though some hybrid

are attracting more interest for these weight-sensitive
applications as their excellent stiffness and strength are
combined with a low density. Unfortunately, the high
stiffness and strength of these composites come at the
expense of their limited toughness. Like most materials,
fiber-reinforced composites also face the strength versus
toughness dilemma. Because of the drawbacks of these
toughening strategies and the strong need for new
lightweight materialswithimprovedtoughness,theresearch
interested in “hybridization”,
Fiber hybridization is a promising strategy to toughen
composite materials. By combining two or more fiber types,
these hybrid composites offer a better balanceinmechanical
properties than non-hybrid composites. Predicting their
mechanical properties is challenging due to the synergistic
effects between both fibers.
TESTING STANDARDS AND TESTINGEQUIPMENT
ASTMSTANDARDS
ASTM International,formerlyknownasAmericanSociety for
Testing and Materials, is an international standards
organization that develops and publishes voluntary
consensus technical standards for a wide range of
materials(i.e composite materials also), products, systems,
and services.
ASTM International is providing no-cost public access to
important ASTM standards, whichareusedinthe production
and testing of materials...etc
Here we discuss some of the testing standards (ASTM) of
composite materials whereas the testing like tensile testing,
impact testing, flexural testing.
ASTMD638
ASTM D638 is the most common testing standards for
determining the tensile properties of the reinforced
composite.
The dimensions for ASTM D638 is 3.2×19×165 .The
specimen is of dog bone shape and other dimensions are
shown in the following diagramandSpecimenispreparedas
per the standards
Specimen Dimensions of ASTM D638
ASTMD790
ASTM D790 is one of the testing standard used for
determining the flexural propertiesforreinforcedcomposite
and its dimensions are 3.2mm x 12.7mm x 125mm (0.125" x
0.5" x 5.0") .The following figure gives the shape and sizes of
the specimen.
Specimen Dimensions of ASTM D790
ASTM D256
ASTM D256 is the testing standard used for determining the
toughness of the reinforced composite. The standard size of
specimen for ASTM D256 is 64 x
12.7 x 3.2 mm. The most common specimen thickness is 3.2
mm, but the preferred thickness is 6.4 mm because it is not
as likely to bend or crush. The depth under the notch of the
specimen is 10.2 mm.

TESTING EQUIPMENT
Continued advancements in the design and manufacture of
engineered composites have allowedcompositematerialsto
work their way into the productsweuseeveryday.Themost
common modern advanced composites are fiber-matrix
composites and they can be manufactured with polymer,
carbon, metal, or ceramic matrix and an extremely wide
range of reinforcement fiber including, carbon, boron,
aramid, natural fibers and glass.
ASTM and ISO have developed standard test methods for
testing compositematerials.Standardsprovidemethodsthat
can be recreated, ensuring materials are tested in the same
manner and within the conditions and allowing test results
validation between manufacturers and customers.
Our composite material gone through four different tests
tensile testing, flexural strength testing, impact testing and
SEM Analysis. Following information gives the information
of the equipment
Tensile Testing
Tensile testing is used to measure the tensile strength of the
specimen. Most common testing machine used in tensile
testing is the universal testingmachine.Thistypeof machine
has two crossheads; one is adjusted for the length of the
specimen and the other is driven to apply tension to the test
specimen. There are two types: hydraulic powered and
electromagnetically powered machines.
Alignment of the test specimen in the testing machine is
critical, because if the specimen is misaligned, either at an
angle or offset to one side, the machine will exert a bending
force on the specimen. This is especially bad for brittle
materials, because it will dramatically skew the results.This

situation can be minimized by using spherical seats or U-
joints between the grips and the test machine.
The strain measurements are most commonly measured
with an extensometer. The data is often used to select the
materials which are strong enough to withholdtensileloads.
The following figure shows the tensile testing machine.

Flexural Testing
The flexural test measures the forcerequiredtobenda beam
under three point loading conditions or four point load
condition. Here we use three point load condition. The data
is often used to select materials for parts that will support
loads without flexing.
Most commonly the specimen lies on a support span andthe
load is applied to the center by the loading nose producing
three point bending at a specified rate. The parameters for
this test are the support span, the speed of the loading, and
the maximum deflection for the test. These parameters are
based on the test specimen thickness and are defined
differently by ASTM and ISO. For ASTM D790, the test is
stopped when the specimen reaches 5% deflection or the
specimen breaks before 5%.
Izod Impact Testing
Izod Impact is a single point test that measures a materials
resistance to impact from a swinging pendulum.Izodimpact
is defined as the kinetic energy needed to initiate fracture
and continue the fracture until the specimen is broken. Izod
specimens are notched to prevent deformation of the
specimen upon impact. This test can be used as a quick and
easy quality control check to determine if a material meets
specific impact properties or to compare materials for
general toughness.
The specimen is clamped into the pendulum impact test
fixture with the notched side facing the striking edge of the
pendulum. The pendulum is released and allowed to strike
through the specimen. If breakage does not occur, a heavier
hammer is used until failure occurs.
Izod Impact Testing Mach
SEM Analysis
A scanning electron microscope (SEM) is a type of electron
microscope that produces images of a sample by scanning it
with a focused beam of electrons and used to reveal micro
structural information of fractured surfaces of composites.
To obtain a high quality image the sample should be
conductive. But there are some non conductive samples and
beam sensitive samples.
Those types of samples are more challenging and require an
extra step as the sample is prepared to gather high-quality
information. This extra step involves coating your sample
with an additional thin layer of about10nanometers(nm)of
a conductive material such as gold, silver, platinum, or
chromium. This carried procedureforpreparationofsample
is called SPUTTER COATING.
Then the prepared sample is further studied in SEM to
obtain the micro structural information of fractured surface
and also the bonding betweentheMatrixandReinforcement.

COMPOSITEPREPARATION ANDTESTING
The following are the series of steps involved from the
mould making to the final step of testing of the composite.
The series of steps are
1. Mould Preparation
2. Preparation of polyester resin(matrix)
3. Anti adhesive coating
4. Fiber preparation
5. Hand layup
6. Curing
7. Preparation of specimens
8. Testing
1. Mould Preparation
Moulds can be made from a wide variety of materials and in
a number of ways but moulds for composites need to be
compatible with the resin system and curing. We used glass
mould for making the composite specimen and also using
glass gives good finish to the composite specimens.
The mould used for preparing composites is made from
rectangular glass having dimensions of 200 mm× 200 mm.
Four glass beadings were used to maintain a 3mmthickness
all around the mould .The another glass plate is used to
cover and compress the fiber after the resin is applied, and
also to avoid the debris from entering into the composite
parts during the curingtime

Mould and Covering Glass
1. Preparation of Polyester Resin
Unsaturated polyester resin has been chosen for matrix for
its good cross- linking tendency and process ability. For 100
ml of resin, 0.75 ml of MEKP (Methyl Ethyl Ketone Peroxide)
and 0.65ml of Cobalt octoate were taken at ambient
temperature as per the manufacturer’s recommendations.
100ml Polyester resin is taken in to a beaker and by using
transfer pipette dropper the appropriate amount of catalyst
and accelerator is mixed with the resin .For stirring a
wooden stick is used.
2. Wax Coating
A thin layer of anti-adhesive coat or mould releasingagentis
applied to the mould surface for easy extraction of the
composite from the mould.
We used solid wax as an anti adhesive coating and is applied
on the glass mould evenly .wax melts on slight heating so
that it makes easy to remove the composite from the mould.
Wax Coated Mould
3. Fiber Preparation
Coir and hemp fibers are combed such that to remove the
shorter fibers and the remaining longer fibers are trimmed
such that they can fit into the mould perfectly.
As mentioned in the chapter 4 about the combination of
fibers and resin, the fibers are weighed according to the
proportions and fibers are mixed according to the intrayarn
(fiber to fiber) hybrid configuration.
4. Hand Layup
Hand lay-up, which is the most common and widely used
open mould composite manufacturing process. Initially, a
thin layer of anti adhesive coat (wax) is applied on the glass
mould for easy extraction. Then small amount of the
polyester resin is poured or applied using a brush in the
mould and the prepared fibers are placed in theglassmould.
The remaining resin is applied on the fibers and a roller is
used to force the resin in to the fabrics to ensure an
enhanced interaction between the reinforcement fibers and
polyester resin (matrix) and same procedure is used for the
all the samples.
5. Curing
After the completion of hand layup procedure the moulds
are allowed to cure about 24 hours. The process of curing of
occurs in three main phases: pre-gel, gel point and post-gel.
During the pre-gel phase, the material mayflowandundergo
molecular rearrangement here we used roller to force the
resin in the fibers .Gel point where the resin is thick and
viscous in nature and final phase post gel here the resin gets
harder. For better hardness we allow it to cure about 24
hours.
After curing the moulds are heated up in Owen so that the
wax gets melted and allows for easy extraction of composite
from the glass mould.
Mould After Curing
6. Preparation of Specimens
Removed composites are cleaned and cuttingoperations are
performed on the composite to get them for the required
dimensions and shapes as according to the ASTM
STANDARDS which are mentioned in the
7. TESTING STANDARDS AND TESTING EQUIPMENT.
Cutting of Specimen
After Cutting the Specimen
8. CONCLUSION
In tensile tests different combinations of hemp and coir
given poor results but as expected the sample with totally
hemp fibers had given great results and As the coir
percentage is increasing the tensile strength is decreasing
this shows coir fiber is poor in tensile strength.
Hybridization of coir and hemp fibers with weight
percentage of 15 and 5 (sample C15H5) respectfully has
given better results in flexural and impact test when
compared to the other samples

In sem analysis we observed fiber pullouts and voids caused
due to fiber pull outs this is all due to hydrophilic character
of natural fibers which results in poor interfacial interaction
between the resin matrix and fibers
Also observed the trapped air bubbles and internal voids
which are caused due to improper rolling and improper
curing. The cracks and the striations are caused due to
sudden forces applied on the composite and load variation
also causes these striations
Further research work needs to be carried out in the
developed of natural fiber composites. This is important if
new improved materials are to be developed for safe usage
against crack growth and environmental pollution. Hybrid
fiber composites with coirandhempfibersmayopenup new
applications. Howeverasinferredfromtheresultspresented
here, significant improvements in flexural strength and
toughness characteristics are noticed for this class of
materials.
