摘要

Polyetheretherketone(PEEK) is a high-performance engineering thermoplastic polymer that is ideal for customized and replaceable parts due to its good mechanical and thermal properties. Fused filament fabrication (FFF) technology has the advantages of low cost, high efficiency, safety, and controllability. However, specimens produced by FFF often have weak mechanical properties. Reinforcing PEEK with carbon fibers (CF) is a solution to improve its mechanical properties. Additionally, CF can improve and modulate the electrical and thermal properties of PEEK. Nevertheless, the FFF manufacturing process for CF/PEEK composite parts encounters many difficulties and challenges. These issues have hindered the application and development of 3D-printed CF/PEEK composites. This review summarizes the FFF forming mechanisms for carbon fiber-reinforced PEEK composites. It focuses on the interfacial properties and performance tests of CF/PEEK composites. Finally, the challenges and remaining issues in FFF technology for carbon fiber-reinforced PEEK composites are summarized. This review provides a reference for researchers to further develop CF/PEEK composite parts with excellent properties.
