AbstractPolyetheretherketone (PEEK) composites reinforced with carbon fibers (CFs) and nano-ZrO2 particles were prepared by incorporating nanoparticles into PEEK/CF composites via twin-screw extrusion. The effects of nanoparticles on the mechanical and wear properties of the PEEK/CF composites were studied. The results showed that the incorporation of nano-ZrO2 particles with carbon fiber could effectively enhance the tensile properties of the composites. The tensile strength and Young's modulus of the composites increased with the increasing nano-ZrO2 content. The enhancement effect of the particle was more significant in the hybrid reinforced composites. The compounding of the two fillers also remarkably improved the wear resistance of the composites under water condition especially under high pressures. It was revealed that the excellent wear resistance of the PEEK/CF/ZrO2 composites was due to a synergy effect between the nano-ZrO2 particles and CF. CF carried the majority of load during sliding process and prevented severe wear to the matrix. The incorporation of nano-ZrO2 effectively inhibited the CF failures through reducing the stress concentration on the carbon fibers interface and the shear stress between two sliding surfaces. It was also indicated that the wear rates of the hybrid composites decreased with the increasing applied load and sliding distance under water lubrication. And low friction coefficient and low wear rate could be achieved at high sliding velocity. (C) 2011 Elsevier Ltd. All rights reserved.
