Experimental investigation and analysis of mechanical properties of injectionIAEME Publication
The document experimentally investigates the mechanical properties of injection molded jute and glass fiber reinforced hybrid polypropylene composites. Composites with varying weight percentages of jute and glass fibers were tested for tensile, flexural, impact and hardness properties. The results showed that all the mechanical properties increased with increasing glass fiber content, as glass fibers have better adhesion to the matrix and higher strength than jute fibers. SEM images showed glass fibers fracturing and pulling out, along with jute fiber pull-out, under applied loads. The hybrid composites thus require greater forces to fail due to the combined effects of different fiber types.
This document describes research into developing glass/banana fiber reinforced epoxy composites. Banana fibers were obtained from banana plants and characterized. Glass and banana fibers were combined at various weight fractions and arranged interleaving to reinforce epoxy composites. The composites were tested for tensile strength, flexural strength, and impact strength. Hybrid composites showed improved mechanical properties compared to glass-only and banana-only composites. Specifically, tensile strength increased by up to 2.5% for glass and 63.4% for banana when hybridized. Flexural strength increased up to 6.9% for glass and 27.3% for banana when hybridized.

This study experimentally investigates the effect of hybridizing jute and glass fibers on the mechanical properties of polyester composites. Jute fiber reinforced polyester composites (JFRPC), glass fiber reinforced polyester composites (GFRPC), and various hybrid fiber reinforced polyester composites (HFRPC) were fabricated and tested. Tensile and flexural testing showed that HFRPC exhibited higher strength properties than JFRPC or GFRPC alone, due to the combined properties of both natural jute and synthetic glass fibers. In particular, composites with 2% jute fiber and varying amounts of glass fiber achieved comparable strengths to GFRPC at a lower cost. Therefore, hybridizing jute and glass

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.

Analysis of Composite Material Blended With Thermoplastics and Jute FibreIJERA Editor
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.

Three compositions of fly ash and epoxy resin were tested as core materials: 65%-35%, 60%-40%, and 55%-45%. The 60%-40% composition showed the best results for flexural and compressive strength testing. Density, flat-wise compressive strength and modulus, and other mechanical properties were evaluated based on ASTM standards. Previous literature on similar sandwich composites and on using fly ash and fibers in epoxy is also summarized.
1) The study investigated the effect of short coir fiber reinforcement on the flexural properties of polymer composites at varying fiber weight percentages (5-25%) and thicknesses (3-5mm).
2) Testing found that flexural strength and elongation increased with fiber content up to 20% reinforcement, but then decreased at 25%. The 20% reinforced 4mm thick composite exhibited the highest flexural strength and elongation.
3) Increasing fiber content improved bonding between the coir and polymer matrix, while higher contents led to more porosity and weaker properties. Coir was shown to be an effective and lightweight reinforcement for polymer composites.

The optimal parameters that resulted in the lowest wear rate were found to be A3 (30% ramie), B1 (580g load), and C2 (2000m sliding distance). Sliding distance was the most significant influencing factor on wear, followed by load, while fiber proportion was the least influencing. SEM analysis showed micro-plucking, micro-cutting and micro-cracks on worn surfaces. The Ra10
This paper present the state-of-the-art literature review and explore the research guidelines
on natural fibres polymeric composites. Due to the environmental issues, cost reduction and high
performance of engineering applications, the demand of natural fibre is increasing day by day.
Reinforcement with natural fiber in composites has recently gained attention due to low cost, easy
availability, low density, acceptable specific properties, ease of separation, enhanced energy
recovery, bio-degradability and recyclable in nature. To safeguard the environment, efforts are being
made for recycling different wastes and utilise them in value added applications.
This document analyzes the mechanical and thermal properties of polyester hybrid composites reinforced with jute and glass fibers. Three composite materials were made with different weight ratios of polyester resin, jute fibers, and glass fibers. Testing found that adding jute and glass fibers increased density, impact energy, tensile strength, and flexural strength but decreased mass loss with temperature and water absorption. Scanning electron microscopy showed fiber pull-out and interaction between fibers and resin. The hybrid composite with more jute fiber had better thermal stability and less water absorption than composites with more glass fiber.

Experimental study of the effect of hybridization on Mechanical
Behavior of Jute/Glass Fibers Reinforced Polyester Composite
Material
Amit Kumar, N.K. Batra, Rajesh Khanna
(Department of Mechanical Engg., Maharishi Markandeshwar University, Mullana)
1. Abstract
Natural fibers are being increasingly
used to substitute artificial glass and carbon
fibers in polymer composites. It is important to
know how the mechanical properties of these
natural fiber composites compare with those of
the traditional glass and carbon fiber composites.
Glass and carbon fiber composites are currently
being used in many applications that may not
require such high-strength materials a lower
strength jute fiber composite may be adequate.
Natural fiber composites are currently being
used in mostly non-structural applications. The
present work focus on the hybridization of
natural fiber (jute) and synthetic fiber (glass)
with polyester resin. Hybridization of jute fiber
along with glass fiber produces better tensile and
flexural strength than GFRPC and JFRPC at
same wt. percentage of fibers.
Keywords – FRP Composite, JFRPC, GFRPC,
HFRPC, Tensile Strength, Flexural Strength.
2. Introduction
For years, composite materials have
growing applications in different industries.
Composite is a mixture of two or more
constituents/materials (or phases) with different
physical/chemical properties at the macroscopic or
microscopic scale. In general composites have two
or more constituents, fiber and matrix. Composites
are classified by the geometry of the reinforcement:
particulate, flake, and fibers or by the type of
matrix: polymer, metal, ceramic, and carbon. The
basic idea of the composite is to optimize material
properties of the composite, i.e., the properties of
the matrix are to be improved by incorporating the
reinforcement phase. Fibers are the principal load-
carrying constituents while the surrounding matrix
helps to keep them in desired location and
orientation and also act as a load transfer medium
between them [1]. The effective properties of the
fiber reinforced composites strongly depend upon
the geometrical arrangement of the fibers within the
matrix [2]. This arrangement is characterized by the
volume fraction, the fiber aspect ratio, fiber spacing
parameters and orientation angles of fibers.
Thermoplastic composites reinforced with long
fibers, short fibers and mat (fabric) of natural and
synthetic fibers like hemp, jute banana, glass,
carbon, Kevlar etc are used in a variety of
applications such as aerospace elements, automotive
parts, marine structures, structural members and
antivibration applications due to their combined
properties of resilience, creep resistance, high
strength to weight and stiffness to weight ratios,
corrosion resistance and good damping properties
[3, 4, 5]. Due to inherent advantages of composites
over traditional materials like metals, their
utilization over the last decade increased many folds
in the field of design of many engineering and
structural components [6]. Many researchers have
analytically and experimentally investigated [7-12]
the mechanical properties (tensile, flexural,
toughness, fatigue etc.) of FRP composites and other
used finite element analysis [13-17] to predict the
behavior of FRP and their mechanical properties.
3. Experimental Setup
3.1 Raw Material
The composite materials used in this
research work were fabricated by reinforcing Jute
fiber and Glass fiber in polyester resin by wt
percentage of 2%, 4%, 6%, 8%.Jute fiber are natural
fiber having good interfacial strength with polymer
matrix while glass fiber are synthetic material
having better strength than jute fiber. By taking the
advantage of both fibers, Hybrid composite were
manufactured.
3.2 Fabrication of composites
There are many composite manufacturing
techniques available in industry [22-24].
Compression molding, vacuum molding, pultruding,
and resin transfer molding [25] are few options. The
hand lay-up [26] manufacturing process is one of
the common techniques to combine resin and fabric
components. This process allows manual insertion
of fiber reinforcement into a single-sided mould,
where resin is then forced through fibers into mould.
A primary advantage to the hand lay-up technique is
its ability to fabricate very large, complex parts with
reduced manufacturing times. Additional benefits of
hand lay-up process are simple equipment and
tooling that are relatively less expensive than other

manufacturing processes. All composite specimens
were manufactured using hand lay-up process.
3.3 Test specimens
The composite specimens were produced in
rectangular size as per ASTM standards, ASTM
D638 (160x19x4.5 mm) for tensile tests and ASTM
D790 (130x12x4 mm) for flexural tests as shown in
Figure:

4. Test Apparatus and Procedure
All experimental tests were carried out at central
institute of plastic engineering and technology
(CIPET) Panipat, Haryana.
Fig. 2: Autograph Machine
4.1 Tensile test
The tensile tests were conducted on
Autograph Machine. These tests were carried out on
rectangular specimens (160x19x4.5 mm) at room
temperature. Specimens were placed in the grips and
were and pulled until failure. The test speed was
5mm/min as per ASTM D638 and an
extensometer/strain gauge was used to determine the
elongation and tensile modulus. Fig. 3 shows the
tensile testing apparatus for the various composites.
Fig. 3: Tensile Test
4.2 Flexural test
Flexural testing was carried on rectangular
specimens (130x12x4 mm) of composite using
Autograph Machine at ambient temperature
according to the procedure described in ASTM D-
790. The test was initiated by applying the load on
the specimen at the specified rate. The deflection
was measured by a gauge under the specimen in
contact with it in the center of the support span.
Fig.4 shows the flexural testing apparatus for the
various composites.

5. Experimental Results
The tensile strength and bending strength
of FRP having different wt. % of jute fiber and glass
fiber is shown in table. The experimental results
shows that tensile strength of polyester resin
increases with increasing wt. % of reinforced fiber
also the tensile strength of GFRPC is much more
than the tensile strength of JFRPC.

6. Comparison between JFRPC, GFRPC
and HFRPC
In the present research work comparison
b/w the tensile and flexural strength of JFRPC,
GFRPC and HFRPC having 4%, 6% and 8% wt
percentage of reinforced fiber is done.
6.1 Comparison of Tensile Strength of JFRPC,
GFRPC and HFRPC
The comparison of tensile strength of
hybrid composite with different wt percentage of
jute fiber and glass fiber with jute fiber FRP and
with glass fiber FRP were shown in the figures.
It was found that hybridization of FRP results in
increasing the tensile strength of FRP at relatively
lower cost than glass fiber reinforced polyester
composite. It was concluded that just by reinforcing
2% jute fiber in glass fiber reinforced polyester
composite the tensile strength of composite increase
as comparison to the pure glass fiber reinforced
composite.

6.2 Comparison of Flexural Strength of JFRPC,
GFRPC and HFRPC:
The comparison of flexural strength of
hybrid composite with different wt percentage of
jute fiber and glass fiber with jute fiber FRP and
with glass fiber FRP were shown in the figures.
The experimental results represent that flexural
strength can be improved by hybridization of glass
fiber and jute fiber with polyester matrix as
comparison to single fiber reinforced polyester
composite (JFRPC and GFRPC). It may be due to
the collective effect of properties of jute fiber and
glass fiber with polyester matrix. The results
obtained exclaim that Flexural Strength can be
improved by reinforcement of biodegradable jute
fiber along with glass fiber in polyester matrix.

7. Conclusions
The result shows that with the increase in
wt. percentage of fiber reinforcement the tensile and
flexural strength of FRP composites increases also
the strength of GFRPC is more than the strength of
JFRPC. The combination of both jute fiber and glass
fiber as reinforcement produces better results than
singe fiber reinforced composites. The HFRPC have
high tensile and flexural strength as comparison to
JFRPC and GFRPC. It may be because of high
interfacial strength of jute fiber with matrix and high
strength of glass fiber. Due to the reinforcement of
both fibers the HFRPC have high tensile and
flexural strength. It is observed that by
reinforcement of jute fiber by an amount of 2% by
wt in polyester matrix along with glass fiber
reinforcement produces good and comparable
strength as that of JFRPC and GFRPC. The benefit
of reinforcement of 2% jute fiber in polyester matrix
along with glass fiber reinforcement is that the FRP
becomes economical, biodegradable and
environment friendly.
