The friction and wear behaviors of glass fiber and carbon fiber reinforced MC nylon composites (GF/MCPA and CF/MCPA) under water lubrication were investigated by a MM-200 friction and wear tester. The worn surfaces and wear debris were observed by scanning electron microscope and surface profilometer. The results show that the fiber reinforced MC nylon composite sliding against AISI 1045 steel registers lower friction coefficient under water lubrication than under dry sliding and the wear resistance of the reinforced composites is better than that of MC nylon matrix. CF/MCPA has smaller friction coefficient and higher wear resistance than GF/MCPA. This is attributed to the formation of a uniform and continuous transfer film on the counterpart steel surface of sliding against CF/MCPA. CF/MCPA is characterized by adhesion and transfer, accompanied by slight plowing in sliding against steel, while GF/MCPA is characterized by microcutting.
