PEEK as a special engineering plastic has been widely used in many engineering fields. To improve the thermal properties and mechanical properties and tribological performance and processing properties of the composites by various means benefit reducing its cost and farther expanding its applications. Recent research achievements of PEEK

chemical modification and physical modification including fibre reinforcing

inorganic fillers

surface modification

blending

have been reviewed in this article. The wide applications in the field of industry

electronics

aviation

automobile and medicine

were summarized briefly. In the end

the paper also provided a prospect for the questions and solutions in the terms of PEEK modification.
