　　Processing method: Injection molding

　　The commonly used fiber materials for fiber-reinforced modified PEEK are carbon fiber (CF) and glass fiber (GF), but with the development of material technology, a large number of other fiber materials have emerged, such as PTFE fiber, steel fiber, etc.

　　Adding fiber-reinforced materials to polymers can effectively improve the wear resistance of PEEK composites and reduce production costs. However, there are certain limitations in the production process of fiber-reinforced PEEK composite materials. For example, in the hot pressing process, the fiber and PEEK mixing process is prone to fiber solidarity, resulting in poor uniformity of the mixture.

　　The main problems with PEEK in practical applications are:

　　(1) Poor surface adhesion, weak interface bonding with fillers, poor thermal conductivity, and susceptibility to thermal expansion, deformation, and fatigue;

　　(2) The wear resistance still cannot meet the needs of engineering, such as support materials, sealing rings, valves, etc;

　　(3) Forming and processing are relatively difficult. PEEK has a melting temperature of 334 ℃, high melting viscosity, high processing temperature, and unstable processing technology.

　　With the development of technology in various fields, there is an increasing demand for the performance of materials. Therefore, research on modifying PEEK and expanding its application scope has become a hot topic in the industry.
