In this paper, polyphenylene sulfide/ polytetrafluoroethylene (PPS/PTFE) composites reinforced with short carbon fibers (CF) were prepared by extrusion and subsequently injection-molding. The mechanical and tribological properties of PPS/PTFE were improved by the incorporation of CF. At the CF loading of 15vol%, the average frictional coefficient and specific wear rate of PPS/PTFE/CF composite under loading of 500N reached to 0.09 and 5.52•10-6 mm3/N•M respectively. The SEM photographs of worn surface confirmed that the direct contacted area between steel ring and the matrix PPS was decreased due to the existence of CF. Meanwhile, CF might be helpful to the formation of strong transfer film under high loading, thus improved the wear resistance of PPS/PTFE.
