Tribological Research on Polyetheretherketone Self-lubricating Composites and Applications

A review of updating the state of friction and wear studies of polyetheretherketone(PEEK) composites was presented.PEEK is a semicrystalline,high performance engineering thermoplastic with a very good combination of thermal,mechanical and tribological properties for a wide spectrum of engineering applications where self-lubricating,thermal,and chemical properties are critical to performance.The improvement of tribological properties of PEEK by fabricating composites with fillers such as fibers of glass or carbon,some inorganic fillers and some polymers was summarized.The effects of temperature,counterface surface and self-lubricant on the wear and friction of PEEK matrix composites were discussed.The biocompatibility of PEEK for orthopaedic implants and tribological application were introduced.The further investigation of the PEEK self-lubricating composites was prospected.
