It is an important subject that the tribological properties are investigated for the combination of the polymer composites from the standpoint of the lighter weight, the miniaturization and the low cost of the machine elements. In this study, the friction and wear properties are investigated for the combination state of pitch carbon fiber reinforced PPS (Polyphenylene Sulfide) composite materials. This tribological test under the rolling-sliding and the light load condition is carried out for the pure PPS resin and three types of PPS matrix composites, which short pitch carbon fibers are varied to 15, 30, 45 wt.%. It becomes clear that the transfer film is formed on various combination conditions of PPS composites and the decrease of frictional coefficient is caused by this transfer film. Also, this transfer film is formed on the surface of the test piece of higher fiber content for all test conditions except the condition of the no filler test piece. And, in the case of the combination conditions of CF/PPS composites, the friction and wear properties are not improved by increasing the higher carbon fiber content. As a result, the better tribological properties are showed on the case of the combination of 15% carbon fiber filled PPS composite and 45% one.
