Progress of tribology investigation of polyether-ether-ketone composites

The recent study progress in the tribological investigation of polyether ether ketone (PEEK) composites is evaluated in detail. PEEK is a high performance thermoplastic polymer, but its friction and wear properties will deteriorate at high temperature. The approach to overcome the detrimental effects of high temperature on the tribological performance of PEEK has been made. The load bearing capacity, strength, and low friction characteristics of PEEK can be enhanced by addition of polytetrafluoroethylene (PTFE), polyetherimide (PEI) and thermotropic liquid crystalline polymer (TLCP) fillers, as well as inorganic fillers including inorganic nanoparticle. The friction and wear behaviors of the filled PEEK composites are summarized. The different structures and component affecting the tribological properties are discussed. The ways for improving PEEK's properties are reviewed and prospected.
