I. INTRODUCTION
Two or more materials are used make composite materials
for their unique properties. This definition is general for
metals alloys, plastic co-polymers, minerals, and wood.
Human beings did not invent the composite; it is found in
nature. An example is wood, which is a composite of
cellulose fibers in a matrix of natural glue called lignin. The
shell of invertebrates, such as snails and oysters, is an
example of a composite. Such shells are stronger and
tougher than fabricated advanced composites. Scientists
have found that the fibers taken from a spider’s web are
stronger than synthetic fibers. The reinforcements can be
made from polymers, ceramics, and metals. The fibers can
be continuous, long, or short. Composites made with a
polymer matrix have become more common and are widely
used in various industries. This section focuses on
composite materials in which the matrix materials are
polymer-based resins. They can be thermoset or
thermoplastic resins. The reinforcing fiber or fabric provides
strength and stiffness to the composite, whereas the matrix
gives rigidity and environmental resistance. Reinforcing
fibers are found in different forms, from long continuous
fibers to woven fabric to short chopped fibers and matrix.
Each configuration results in different properties. The
properties strongly depend on the way the fibers are laid in
the composites. All of the above combinations or only one
form can be used in a composite.
II. MATERIALS AND METHODS
This chapter describes the details of processing of the
composites The raw materials used in this work as follows
 Jute fiber
 Glass fiber
 Resin
Glass fiber is commonly used as an insulating
material. It is also used as a reinforcing agent for many
polymer products; to form a very strong and light fiber
(FRP) composite material called glass-reinforced plastic
(GRP), popularly known as "fiberglass". Glass fiber has
roughly comparable properties to other fibers such as
polymers and carbon fiber. Although not as strong or as
rigid as carbon fiber, it is much cheaper and significantly
less brittle. Glass fiber is formed when thin strands of silica-
based or other formulation glass are extruded into many
fibers with small diameters suitable for textile processing
Jute fibre has some unique physical properties like high
tenacity, bulkiness, sound & heat insulation property, low
thermal conductivity, antistatic property etc. Due to these
qualities, jute fiber is more suited for the manufacture of
technical textiles in certain specific areas. Moreover, the
image of jute as a hard and unattractive fiber does not affect
its usage in technical textiles. In this project, work epoxy
used is polyflex GR.200-14. The choice of a resin system
for use in any component depends on a number of its
characteristics, with the following probably being the most
important for most composite structures
1) Adhesive properties
2) Mechanical properties
3) micro-cracking resistance
4) Fatigue resistance
5) Degradation from water ingress.
6) Racking resistance
A. Specimen for Testing:
Each composite board was cut into test samples. The cutting
processes were using handsaw and other equipment’s. All
specimens test were conditioned based on the standard
procedures of ASTM. The test specimens were done in the
room condition of 23 ± 2 0C in temperature and with
relative humidity 50±5% for not less than 40 hours prior to
the property assessment test.

III. RESULT AND DISCUSSION
Tensometer apparatus is used find the tensile strength of the
composite specimen. Tensometer is the device used to find
the young’s modulus of a material and other tensile
properties of materials.

IV. CONCLUSION
This work shows that successful fabrication of jute fiber
reinforced epoxy composites with different fiber lengths is
possible by simple hand up technique and the mechanical
properties are analyzed. The tensile and impact properties
are higher than other fiber-reinforced composites and water
absorption capacity is less compared to sisal and banana
fiber. It is important to remark that results show that
automotive components made of natural composites are to
be lighter than glass composites to present better
environmental performance.
