1. INTRODUCTION
In recent years, polymeric based composite materials are finding increasing use in many
applications due to their strength, lightness, ease of processing, high wear resistance and
low-cost. Properties of composites are not only dependent on the properties of their
constituent materials, but also their distribution and the interaction among them. They are
widely used in many industrial applications such as structural, aerospace, automobile and
chemical. Addition of fillers in polymeric composite enhances mechanical, tribological and
other properties and also there is a cost reduction in terms of consumption of resin
material.The critical and final selection of filler primarily depends upon the requirements of
the end products.A literature survey indicated that the addition of tungsten disulphide as a
filler with 4 microns size is thoroughly mixed with epoxy resin in seven different volume
percentages by simple mechanical stirring. The investigation studied by J. S. Sidhu et. al. [1]
led to the conclusion that Polymer composites suitable for Engineering components
subjected to wearing environments can be successfully prepared by filling in micro WS 2 .
Research work in the field of mechanical properties of the polymer dominated by
Srivastavaet. al. [2]showed thatthe fracture toughnessof epoxy resin could be improved by
fly ash particles as fillers. The fillers affect the tensile properties according to their packing
characteristics, size and interfacial bonding. The maximum volumetric packing fraction of
filler reflects the size distribution and shape of the particles. Lingarajuet. al. [3] studied the
mechanical properties of fiber-reinforced composite, which showed improvement by the
inclusion of nanoparticles. Addition of 1%wt. of silica showed improvement in impact
strength, tensile strength, Barcol hardness and reduction in wear rate. Ricardo Baptistaet. al.
[4] studied the effect of the incorporation of different amounts of graphite filler on the
mechanical properties of epoxy resin and of carbon fiber reinforced epoxy composites.
Graphite-reinforced epoxy resin attained results show that 7.5, 10 and 11.5 wt.%-graphite
results in the best balance of mechanical (modulus, strength, strain) properties and that the
incorporation of graphite as matrix filler in carbon fiber reinforced epoxy results in
improvement on mechanical properties, up to a limiting value. S.Pichi Reddy et. al. [5]
investigated tensile and flexural behavior of fly ash reinforced glass fiber epoxy composites
with different weight percent of fly ash. The results showed that with increase of fly ash
better tensile strength is obtained and flexural strength decreases, reaches a maximum value
and again decreases with the addition of fly ash in the epoxy matrix. Manoj Singla and
Vikas Chawla [6] investigated the Mechanical Properties of Epoxy Resin – Fly Ash
Composite with the addition of fly ash and then by reinforcing glass fiber. With the addition
of fly-ash in epoxy resin –fly-ash composite the compressive strength has been found to
increase with increase in fly ash particles and after reinforcing glass fiber both compressive
& impact strength has been increased. J.M. Wernik, S.A. Meguid [7] investigated the
mechanical properties of carbon nanotube reinforced epoxy adhesives experimentally. The
experimental observations indicate a critical carbon nanotube concentration in the vicinity
of 1.5wt% that results in the largest improvements in the mechanical properties. At
concentrations exceeding this critical value, the properties begin to degrade, in some cases,
