It is a carbon fiber composite material with excellent mechanical strength and high thermal dimensional stability. Materials are commonly used in the field of trauma, such as internal fixation systems (aiming arms), external fixation systems, and other structural components.

PEEK, as a typical high-performance thermoplastic resin and the leader of special engineering plastics, has outstanding performance in various aspects. When combined with continuous carbon fibers, it effectively combines the performance of the two materials, resulting in even better overall performance. Continuous carbon fiber CF/PEEK thermoplastic composites have been widely used in aerospace, military, medical, automotive and other fields due to their excellent performance, and are currently the focus of research and attention in major universities, research institutions, and enterprise units.
