In comparison to metals, generally unfilled polymers have low thermal conductivity and low wear resistance. Therefore, various filler and reinforcements are frequently added to the unfilled polymers to improve their tribological and thermal properties. So, filled polymers are preferred for many industrial sectors such as aircraft, automotive, electrical/electronic and household application. Friction and wear behaviour is one of the most important properties of polymer and its composites. Therefore, many studies on friction and wear properties of polymer and its composites have been carried out.
