Research on High-performance PEEK Composites

Abstract Polyetheretherketone (PEEK) has excellent comprehensive properties, but compared with traditional materials, it has many disadvantages, such as small modulus of Elasticity, small impact force, high melting point and so on. In order to improve the properties of PEEK composites, this paper summarized the improvement schemes of the mechanical properties, electrical conductivity, friction resistance, high temperature resistance and other properties of PEEK and its composites. The properties of PEEK composites filled with carbon nano-materials, fibers and whiskers were reviewed, and the research progress of modified PEEK composites in recent years was introduced, the aim is to improve the comprehensive properties of composite materials by adding a small amount of materials. And the development situation and the law were summarized from some certain degree. In the end, the development direction and trend of PEEK composites were prospected.
