This kind of the composite showing an excellent strength to wear resistance. In this review presents the friction & wear behaviour of the polymer composites and used the various test apparatus. Result reveals that polymer composites filled by various filler material such as SiC, WC, SiO2 and Graphite particles etc. Effect of this fillers it improves the properties of PMC like flexural strength, shear strength and wear resistance etc. Keywords – Polymer composite, Filler, Friction and Wear. 1. INTRODUCTION Composites are thus made by combining two distinct engineering materials in most cases one is called matrix that is continuous and surrounds the other phase – dispersed phase. The properties of composites are a function of the properties of the constituent phases, their relative amounts, and size-and-shape of dispersed phase. They consist of mainly three different types. Among them polymer matrix composite (PMC) and metal matrix composite (MMC) are the commonly used in large scale. Fibers place an important role in the field of industries, automobile, military applications. Over the past years, polymer composites are made and most commonly used for structural applications in the aerospace, automotive, and chemical industries, and in providing replacements to traditional metallic materials. 1.1 Fiber Polymer composites are mixtures of polymers with inorganic or organic additives having certain geometries (fibers, f- lakes, spheres, particulates). Thus, they consist of two or more constituents & two or more phases. The additives may be continuous, e.g. long fibers or ribbons. This type of composite is used in the highest diversity of composite applications due to its advantages such as low density, good thermal, ease of manufacture, and low cost. The properties of polymer matrix composites are generally determined by three constitutive basics such as the types of reinforcements (particles and fibres), the type of polymer, and the interface between them. Polymers are allocated into two categories such as thermoplastics and thermosets. Thermoplastic are in common, ductile and tougher than thermoset materials. They are reversible and can be redesigned by present of heat and pressure. Thermoplastic molecules do not cross-link and so they are flexible and reformable. The most general resin materials utilized in thermoset composites are epoxy, polyester, phenolic, vinyl ester, and polyimides. 1.2 Filler Depending on the sort of filler forms the addition strength to the mechanical properties and tribological properties of the polymer composite materials. In this fillers SiC, WC, SiO2 and Graphite particles etc are used as reinforcement it will increase the properties like tensile strength, young’s modulus, flexural strength and wear resistance. 2. LITERATURE SURVEY B. Suresha et al [1] compared carbon-epoxy (C-E) composite with that of glass-epoxy (G-E) composites for tribological properties using a pin-on-disc set up. The experiment are conducted under different sliding and loading conditions by subjecting C-E samples sliding against a hard steel disc (62 HRC). This paper presents the friction and wear behavior of C-E and G-E composites run for a constant sliding distance, where in the C-E composites show lower friction and lower slide wear loss compared to G-E composites irrespective of the load or speed employed. Nak–Ho Sung et al [2] investigate the friction and wear behavior of composites varying fiber orientations with respect to the sliding direction. Both wear and friction coefficients of graphite fiber-epoxy composites were minimum when the orientation of the fibers was normal to the sliding surface. When the largest fraction of fibers was oriented normal to the sliding surface, glass fiber-Moss-PTFE composites wear was minimum. In Kevlar-epoxy composites the wear rate was minimum but the friction coefficient was the highest, when the fibers were oriented normal to the surface and the sliding direction. Kishore et al [3] studied the slide wear characteristics of a glass–epoxy (G–E) composite, filled with either rubber or oxide particles using a block –on – roller test configuration. At three different loads of 42, 140 and 190, mass loss was determined as a function of sliding distance for sliding velocity between 0.5 and 1.5 m/s. Study showed that oxide
