Abstract
The greatest advantage of composite materials is strength and stiffness together with light weight. By choosing an
appropriate combination of matrix material and reinforcement, manufacturers can produce a property that exactly matches
the requirements for a particular structure for a particular purpose. The present works aims to prepare E-glass fiber
reinforced composite with variation in volume fraction of glass fiber content like 1%, 2% and 3% with Bisphenol A as
matrix material. Tensile and compression tests are conducted on the prepared composite. As a final point of view, the
experimental results are compared with the FEA results by using analysis software like ANSYS.

1. Introduction
Composite materials are an important class of materials
which are now available to mankind in large quantity. In
recent years, many glass fiber-reinforced composite
materials are widely used in the aerospace and automotive
industries. Composite materials are important for
mechanical, chemical and civil engineers, material
scientists for using them on a large amount of engineering
and other applications [1]. The technological development
has increased on advances in the materials field.A
composite material is one, which consists of at least two
materials working together to produce new material with
properties that are dissimilar to the properties of individual
material that they possess. It contains the most important
characteristic that the materials are not soluble to each
other [2]. Most composites are made up by using more
than one material [4]. Most of the commonly used
composite materials have a large phase, which is
continuous, called as the matrix, and one distributed, on-
continuous phase called as the reinforcement, which is
typically stronger and harder [5].Reinforcements are added
primarily to improve the stiffness and strength of the matrix
and are usually available in the fiber form [7].
2. Materials and processing methods
2.1 Selection of matrix material
Bisphenol A, more commonly known as BPA, is a
chemical widely used to make polycarbonate plastics and
epoxy resins.BPA is hardly the only chemical to be
identified as an "endocrine disrupter”. More than 50 such
compounds have been identified. Some cosmetics and soft
plastic toys contain one or more phthalates a group of
chemicals that interfere with testosterone and have been
shown to lead to infertility and cancer.
2.2 Selection of reinforcement material
The Literature survey indicates that very limited work has
been done on the E-glass fiber reinforced epoxy composite.
E-glass fibers were purchased from Binani Goa glass fiber
company, Mumbai. Glass fibers are readily produced from
raw materials, which are now available in unlimited supply.
Binani Chopped Strand Mat is made of randomly, yet
evenly distributed strands, chopped from continuous E-
glass fibers into 50 mm length, bonded with “emulsion
binder” contains better surface bonding efficiency.
2.3 Methods of preparing the composite material
The raw materials used in this work are,
1) Matrix material
2) E glass fiber (chopped strand mat)
3) Hardener
The fabrication of the composites is carried out by the hand
lay-up technique. Composites of three different volume
fraction variations such as1%, 2% and 3% of glass fiber are
made. The matrix material was weighed to the required
quantity and catalyst, accelerator, hardener and glass fiber
were added to the matrix material. Proper mixing was done
using a mechanical stirrer. The glass fibers are randomly
oriented in the matrix. The mixture was then allowed to
settle for some time to reduce the air bubbles. A releasing
agent was sprayed on the surface of the aluminum mould
