Poly(phenylene-sulfide)/ Poly(ether-sulfone) polymer composites (coded as PPS/PES) reinforced by Potassium Titanate Whisker(PTW) and Polytetrafluoroethylene (PTFE) were prepared by compression molding. The effect of the filler on the mechanical and tribological properties of the PPS/PES composites was investigated, based on the evaluation of the composites’ properties and examination of the worn surfaces by means of scanning electron microscopy (SEM). Results showed that the incorporation of the PTW contributed to greatly increase the impact strength,tensile strength,and bending strength of the composites, and apparently improve its tribological performance. The composite had a best synthetical performance when the PTW content was about 20wt. %. The wear mechanism of the composites,which could be closely related to the content of PTW, gradually changed from adhesive wear to particle abrasion with the addition of PTW.
