Abstract: A high-performance carbon fiber reinforced polyether ether ketone(CF/PEEK) thermoplastic composite manufactured through hot-air-heated automated fiber placement has been used extensively in aerospace. However, the elevated melting temperature and high melt viscosity of CF/PEEK present considerable processing challenges when utilizing automated fiber placement manufacturing techniques. This study fabricates CF/PEEK laminates using automated fiber placement. The influence of laying pressure, laying speed, and mold temperature on processing-structure-property relationships is systematically examined, focusing on porosity, crystallinity, and flexural strength. Process parameter optimization of the automated fiber placement process uses response surface methodology. The results show that the laying pressure has a greater effect on porosity. The laying speed has a greater impact on crystallinity and flexural strength. While the mold temperature has less effect on porosity, crystallinity, and flexural strength. The optimal processing parameters combine 800 N laying pressure, 150 ℃ mold temperature, and 8 mm/s laying speed, which provides theoretical guidance for the engineering application of CF/PEEK thermoplastic composites formed by hot-air-heated automated fiber placement.
