  1. INTRODUCTION:

    Polymer is actually an artificial all natural material features little particles recognized as monomers, Epoxy is actually a functional course of particle including one air atom adhered along with pair of carbon atoms and also these carbon atoms actually have actually bound through various other methods, glass fibre being composed very little fibre coatings of glass and also granite as well as stone powder are actually the commercial wastefulness gotten after grinding the granite and also rocks.

    Epoxy material reinforced along with artificial fibres including glass fibre is actually anenormous accomplishment in the business of materials. The combos of polymer based upon composite materials have actually begun brand new methods for the polymer assembly and also have actually permitted the manufacture of brand new items along with ideal properties [2].

    Fillers of Granite and also Stone grains happened under the course of ceramic, these are actually included the kind of powder that indicates featuring remarkably little surfaces and also each surface kind as a clear that connections properly along with Glass fibre Epoxy as well as improves mechanical properties including tensile, flexural, impact, hardness toughness as well as likewise improves the perspective security, protection to wear, operate at heats, enduring protection.

    It is actually typically acknowledged to make use of the SEM devices is actually direct to function; it is actually a notable component in the research of mini constructs at the failing aspect of the all evaluated examples [18].

    There are actually comprehensive specialized requests through which friction and also wear are crucial factors to consider. Polymer composites having various fillers as well as supports [17].

    Among the necessary features of materials are actually wear and also friction. Wear is actually determined as the damage to a strong area, typically pertaining ongoing reduction of material, because of moving activity in between that area as well as speaking to drug or even compounds [12]. To boost the friction as well as wear properties of polymer materials is actually to enhance their hardness, tensile, impact as well as flexural durabilities as well as to minimize their attachment to the getting in touch with component material for this normally making use of the fibre encouragements along with the glass fibre as well as ceramic fillers in the powder kind [9].

  2. METHODOLOGY:

    2.1. Work Sample Preparation:

    A Teflon glass mould of measurements 300 × 200 × 3 mm3 has actually readied, reduced the called for dimension of glass fibre at that point use the silicon mould launch spray on the internal surface area of Teflon glass mould and after that use 1st coating of Epoxy as received Fig.1, insert the 1st level of glass fibre on it as well as use the 2nd coating of Epoxy on glass fibre as received Fig.2 at that point insert the 2nd coating of glass fibre on Epoxy insert and afterwards administer the 3rd level of Epoxy on Glass fire afterwards activity enable sample to become treatment at area temperature as much as 48 hrs after that take out the sample coming from the mould as received Fig.3 and afterwards based upon ASTM specifications reduced the called for dimensions of examples due to the utilizing vertical band viewed machine.

      1. Wear test procedure:

        Fig.5 Pin on disc Wear testing Machine

        Fig.5 demonstrates a pin-on-disk wear testing machine, in which the wear tests were actually carried out. During the course of the test, the wear, friction coefficient as well as friction force was actually tape-recorded and also graphed.

        To explain the tribological practices of polymer materials busy, conventional tests are actually made use of. The pin-on- disc test, some of the best often made use of test setups.

      2. Mathematical Formula for Sliding wear test:

        The specific wear rate WS of the material to be optimized, by using the equation

        Where m is the mass loss before and after sliding, L the sliding distance, the density of the composite, and FN is the normal load.

      3. SEM analysis procedure:

    After the tensile test, the tensile fracture areas, theused surface areas of the composites and also the counter skins are actually covered along with a slim level of gold and after that reviewed making use of a Scanning Electron Microscope (SEM) as displayed in Fig.6.

    Fig.6 Scanning Electron Microscopic machine

    The SEM browses a high-energy electron beam throughout the surface area of a specimen and also determines among a lot of signs coming from the communication in between the beam as well as specimen.

    The SEM photos are actually boring as they mirror the electron on each pixel. They could be colourless to enhance graphic improvement of substances with adjustments in graphic strength [24].
