In recent years, polymers are extensively utilized in tribological components such as cams, brakes, bearings and gears because of their self-lubrication properties, lower friction, better wear resistance, low noise and cost. Polymers are associated with some inherent deficiencies which can be altered successfully by using various special fillers there by producing polymer composites. More and more polymer composites are now being used as sliding components, which were formerly composed only of metallic materials. Polymers used for fabrication of tribological components should have excellent...
