Abstract

Nowadays, friction reduction has become a solution for new automotive engines due to the constraint of reducing power required and carbon dioxide emissions. Increase wear resistance has important effect on useful life of engine parts. In the present work discuss the tribological properties of epoxy composites. Epoxy filled with nano-particles of Al2O3 and different content of paraffin oil were used as bearing materials.  The influence of Al2O3 on tribological properties of epoxy composites is discussed.
 
Test specimens were prepared in the form of cylindrical shape with cross section of 7 mm diameter and 30 mm length. The test specimens were loaded by 10 N weight against counterface of the carbon steel disc.
 
It was noticed that the friction coefficient for epoxy composite decrease to minimum values with increasing aluminum oxide nano-particles up to 6% and 0.4% oil. The aluminum oxide nano-particles decrease the adhesion between epoxy and steel surface and increase the hardness of test specimens. The wear resistance can be increase for epoxy composite by increasing aluminum oxide nano-particles up to 6% and 0.5% oil. The increase of oil content decrease the friction coefficient.
