This document analyzes the properties of a composite material blended with thermoplastics and jute fiber. The composite is made using a hand lay-up technique with jute fabric reinforced polyester resin. Testing shows that the untreated composite has lower tensile strength and hardness than the natural jute fiber, but higher elongation. Scanning electron microscope analysis indicates the distribution of fibers, resin and additives in the composite microstructure. The study concludes that while the composite has lower density than pure resin, resulting in better strength to weight ratio, the mechanical properties are not significantly improved over the natural fiber alone.

Mechanical Behaviour of Agricultural Residue Reinforced CompositesScientific Review
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.

Jute, an eco-friendly and affordable fiber grown profusely in India, possess unique combination of properties suited for the manufacture of non-textile products. However, its contribution for technical applications is limited at present. In this research, an effort has been made to investigate the physical and morphological properties of jute fiber when incorporated in epoxy matrix with a view to widen the share of jute fibers for engineered applications. Composite specimens containing nonwoven jute mat and alkali treated short jute fibers with different weight percentages (1, 2 wt%) were made using epoxy resin. The water absorption, thickness swelling (TS) and morphology [scanning electron microscopy (SEM)] tests of the bio composites were performed. As the fiber fraction ratio was increased the values for water absorption (WA) and thickness swell (TS) were found to be increased. The samples reinforced with 2 wt. percent fiber fractions showed maximum WA and TS in both water environments.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Abstract
Recently natural fibres have been receiving considerable attention as substitutes for synthetic fibre
reinforcements due to their low cost, low density, acceptable specific strength, good thermal insulation
properties, reduced tool wear, reduced thermal and respiratory irritation and renewable resources. The aim of
this work is to develop chemically treated and chemically untreated fibre reinforced composite material with
optimum properties so that it can replace the existing synthetic fibre reinforced composite material for a suitable
application. In this work, polyester resin has been reinforced with jute fabric, so as to develop jute fibre
reinforced plastic (JFRP) with a weight ratio of 10:1:1 Hand lay-up technique was used to manufacture the
composites where Methyl Ethyl Ketone Peroxide and cobalt Naphthalene were used as coupling agent and
accelerator respectively. The thickness of the composite specimen was obtained by laying up layer of fibre and
matrix. The untreated composites have been used and mechanical properties are compared with natural fibre and
jute fibre composite by using the Ansys method.
Keywords: Jute fiber, Epoxy resin, Jute fibre reinforced composite, Tensile strength, Ansys solving.
I. INTRODUCTION:-
Now-a-days, newer polymer matrix composites
reinforced with fibers such as glass, carbon, aramid,
etc. are getting a steadyexpansion in usesbecause of
their favorable mechanical properties.
For this natural fibres such as jute, can be
alternately used to reduce the cost of the composites.
Moreover, production of environmentally friendly
materials is another important issue.The use of
natural fibres, derived from annually renewable
resources, as reinforcing fibres in both thermoplastic
and thermoset matrix composites provide positive
environmental benefits with respect to ultimate
disposability and raw material utilization.The
prominent advantages of natural fibres include
acceptable specific strength properties, low cost, low
density, high toughness, good thermal properties, and
so on. Low specific weight, which results in a higher
specific strength and stiffness than glass is a benefit
especially in parts designed for bending stiffness.
In this work, polyester resin has been reinforced
with jute fabric, so as to develop Jute Fibre
Reinforced Plastic (JFRP) with a weight ratio of
10:1:1 (epoxy resin, methyl ethyl ketone
peroxide,and cobalt naphthalene) Hand lay-up
technique was used to manufacture the composites
where Methyl Ethyl ketone peroxide and cobalt
Naphthalene were used as coupling agent and
accelerator respectively and composites were
prepared under various processing parameters using
manual Hand layup technique.
II. METHODOLOGY
The fibres usually mats, are cut and placed in a
mould, see figure. The resin is applied by rollers. One
option is to cure while using a vacuum bag, then it’s
called vacuum bagging. By applying vacuum, excess
air is removed and the atmospheric pressure exerts
pressure to compact the composite.A possible
product is the boat hull . The advantages are the high
flexibility and the simplicity of the process and the
cheap tooling.
Fig 2.1 Hand layup method
III. FIBRE EXTRACTION PROCESS
The Jute fiber is available from jute tree. When
the plants are about 15 – 20 cm tall, they are thinned
out. About four months after planting, harvesting
begins. The stalks are cut off close to the ground. The
stalks are tied into bundles and soaked in water
(retting) for about 20 days. This process softens the
tissues and breaks the hard pectin bond between the
bast and jute hurd (inner woody fibre stick) and the
process permits the fibre to be separated. The fibre
are stripped from the stalks in long strands and

washed in clear, running water. Then the fibers were
cleaned and dried in sunlight.
IV. CHEMICAL TREATMENT
The rough jute fibres are pre-washed with large
amount of distilled water to remove the surface dirt
present in the fibres and then put in an oven at 100°c
for drying until it gains a constant weight. The
mercerization or alkali treatment is carried out by
immersing the washed jute fibres 200 gms in a 10 %
(w/v) sodium hydroxide aqueous solution 2lt for 3hrs
in a temperature of 70°c. It should be stirred
occasionally and after that the fibres are taken out
and washed in order to remove any absorbed alkali.
Fig 4.1 Jute fibre
V. FIBRE PREPARATION
In order to evaluate the flexural strength of the
composites three point bending test is carried out by
JFPC means cut as per the ASTM D790 to measure
the tensile test. The samples taken for the tensile test
is 160×30×5 mm (length, breadth, height) which is
cut by using a diamond cutter. Care has been taken
for maintaining uniformity and homogeneity of the
composite. The data reported here is the average of
five successful tests.
Fig5.1 Die Pattern
VI. COMPOSITE FABRICATION
Polyester resins are used as matrix in different
type of composites. These materials are noted for
their versatility, but their relatively high cost has
limited their use. High resistance to chemicals and
outstanding adhesion, durability, and toughness has
made them valuable as coatings. Because of their
high electrical resistance, durability at high and low
temperatures, and the ease with which they can be
poured or cast without forming bubbles, polyester
resin are especially useful for encapsulating
electrical and electronic components. Polyester resin
adhesives can be used on metals, construction
materials, and most other synthetic resins. They are
strong enough to be used in place of rivets and welds
in certain industrial applications. Polyester resin is a
thermosetting peroxide polymer that polymerizes and
cross links when mixed with a catalyzing agent or
"hardener". Unsaturated isophthalic polyester resin is
used as polyester resin, 2% cobalt naphthalene (as
accelerator) is mixed thoroughly in isophthalic
polyester resin and then 2% Methyl-Ethyl-Ketone-
Peroxide (MEKP) as catalyst is mixed in the resin
prior to reinforcement. With reinforcement of jute
fibrethe chicken feathers collected from poultry units
are cleaned with a polar solvent, like ethanol, and are
dried. The quills are removed and the short fibres are
obtained. To prepare the composite slabs, these fibres
in pre-determined weight proportion 20% are
reinforced with random orientation into the polyester
resin. A block is thus cast. The casting is put under
load for about 24 hours for proper curing at room
temperature. Specimens of suitable dimension are cut
using a diamond cutter for physical characterization.
The jute particles obtained were used to prepare
composites. To prepare the composite slabs, these
particles in pre-determined weight proportion 20%

polyester resin. The casting is put under load for
about 24 hours for proper curing at room
temperature.

VIII. EXPERIMENTAL PROCESS
8.1 TENSILE TESTING
Tensile testing, also known as tension testing, is
a fundamental materials science test in which a
sample is subjected to a controlled tension until
failure. The results from the test are commonly used
to select a material for an application, for quality
control, and to predict how a material will react under
other types of forces. Properties that are directly
measured via a tensile test are ultimate tensile
strength, maximum elongation and reduction in area
From these measurements the following properties
can also be determined: Young's modulus, Poisson's
ratio, yield strength, and strain-hardening
characteristics.

8.2 BRINELL HARDNESS TEST
The load is applied for a standard time (~30s),
and the diameter of the indentation is measuredin this
test. The impression so obtain is measured by a
microscope and the brinell hardness number B.H.N.
is found out by the following equation.

8.3 ROCKWELL HARDNESS TEST
The determination of the Rockwell hardness of a
material involves the application of a minor load
followed by a major load, and then noting the depth
of penetration from a dial, on which a harder material
gives a higher number. The chief advantage of
Rockwell hardness is its ability to display hardness
values directly, thus obviating tedious calculations
involved in other hardness measurement techniques.

8.4 SCANNING ELECTRON MICROSCOPE
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. The electrons interact with electrons in the
sample, producing various signals that can be
detected and that contain information about the
sample's surface topography and composition. The
electron beam is generally scanned in a raster scan
pattern, and the beam's position is combined with the
detected signal to produce an image.
Figure 8.4SEM Images
8.5 TENSILE TEST RESULT FOR ANSYS
The tensile test is generally performed on ASTM
specimens. The commonly used specimens for tensile
test are the dog-bone type and the straight side type
with end tabs. During the test a uni-axial load is
applied through both the ends of the specimen. The
ASTM standard test method for tensile properties of
fiber resin composites has the designation D790. The
tensile test results of Stress were analysed.

IX. RESULTS
9.1MECHANICAL PROPERTIES
In the present investigation the reinforcement of
jute in short form into polyester resin has not shown
any encouraging results in terms of mechanical
properties. However, there enforcement has caused a
reduction of about 13% in the composite density
which leads to improvement in the strength to weight
ratio. The density of the composite is measured to be
0.97 gm./cc (with void fraction of 1.2%) which is less
than the density of neat polyester resin (1.12 gm./cc)
mechanical properties of SF reinforced urea-
formaldehyde resin composites have been described.
Whereas the flexural, wear resistance and water
absorption properties are proved to be excellent in the
composite with 30 wt.% SF under the present
experimental conditions adopted.

XI. DISCUSSION
Here in this chapter, the important components
used in our project were discussed. Also descriptions
of parts were discussed along with photographic
illustration. The SEM micrographs of impact
fractured and worn surfaces reveal that the proper
jute fibre addition can improve the fracture energy,
strengthen interfaces and lower wear rate.
Here in the microstructure analysis the following
parts were identified,the portion which Projected
outside is indicated by Jute Fibre present in it. A light
grove concludes the Ethyl Methyl Ketone peroxide.
Cobalt Naphthalene was in the form of a grey colour.
Finally the Grains like pattern indicate the
distribution of Epoxy Resin.
The fibres themselves possess a higher wear
resistance than the matrix and should protrude from
the surface after some time. Hence, the applicability
ofthese composites in fibreboard can be expanded.
XII. CONCLUSIONS
The experimental investigation on the effect of
chemical treatment on mechanical behavior of jute
fiber reinforced POLYMER MATRIX
COMPOSITES (PMC) leads to the following
satisfactory conditions.
The experimental conclusions obtained from this
study are as follows:
Jute fibrereinforced PMC can be successfully
fabricated.
The mechanical rate behavior is different for
oblique and at normal impact angles.
The results indicate that angle of impact is the
most important parameter Stress and strain
during mechanical .The angle of impact greatly
affects the mechanical behavior of poultry
feather and jute reinforced polyester matrix
composites.
Jute reinforced PMCs show better resistance to
mechanical compared to coir reinforced PMCs.
Polyester composites showed better resistance to
mechanical composites.
At higher impact angles, high degree of
cavitation along with formation of cracks is
observed in case of all the PMCs.
Steady state mechanical rate is observed in case
of reinforced PMCs at higher time values.
However, the density of the composites
decreases due to the reinforcements which tend to
increase the strength to weight ratio which is an
important parameter in industrial and commercial
application of composite.
XIII. FUTURESCOPE
The present work leaves a wide scope for future
investigators to explore many other aspects of bio-
fibre reinforced polymer composites. Some
recommendations for future areas of research
include.To increase mechanical strength of these
composites for their use in different sectors can be
studied. Environmental study of feather fibre
reinforced polymer composites i.e. the effect of
different environmental conditions like alkaline
medium, acidic medium, freezing temperature etc.
On the properties and/or degradation of these
composites is to be evaluated. Possible use of other
fibres/flakes obtained from bio-wastes in the
development of new composites. Other polymers can
be tried as the matrix material for fabrication of
poultry feather reinforced composites.
