摘要：

This paper presents an investigation into Automated Fibre Placement process parameters for a novel carbon fibre-reinforced thermoplastic material based on a low-melt polyaryl ether ketone polymer matrix (CF/LMPAEK). The primary focus of this investigation is in-situ consolidation, with parameter sets for sample manufacturing selected based on a Design of Experiment method and analysed by means of mechanical and thermal testing. For in-situ consolidation, a maximum shear strength of 33.6 MPa and a crystallinity of 27.3% is achieved. Subsequent tempering increases shear strength up to 46.5 MPa and crystallinity up to 32%. The material was found to be insensitive to layup speed within the tested parameter range (1-15 m/min), achieving similar results for high layup speeds.
