Abstract
The friction and wear properties are investigated in the combination state of pitch carbon fiber reinforced PPS (Polyphenelene Sulfide) composite materials and SUJ2. The tribological tests under the rolling-sliding condition are carried out for the pure PPS resin and three types of PPS matrix composites, which short carbon fiber diameters are varied to 18, 13, 9μm. And, these composites varied to the fiber weight content 15, 30, 45wt% are used as the same test specimens. As a result, it became clear that the different worn patterns on the surface of test specimen were appeared and these patterns changed due to the pitch carbon fiber diameters and the fiber weight content. It was also found that both the coefficient of friction and the specific wear rate decreased and the rolling distance became longer with the increase of the fiber weight content and the decrease of the fiber diameter. Moreover, it was showed that the ratio of interfacial area was an effective parameter in the case of evaluating the rolling distance and the specific wear rate on various composites.
