Carbon fiber reinforced thermoplastic (CFRTP) has high performance properties such as high productivity, recyclability and impact resistance compared to thermosetting composites. Therefore, CFRTP has a wide range of applications in aerospace, automotive and industrial products. The joining process is a necessary step to manufacture complex geometry parts and large-scaled structures using CFRTP. The joining of thermoplastic composites can be divided into several methods such as mechanical fastening, adhesive bonding and fusion joining or welding. The mechanical fastening method has some disadvantages such as stress concentrations, gain of weight and so on. Adhesive bonding method is also difficult to bond chemically between thermoplastic polymers. Therefore, some welding methods has been proposed so far for thermoplastic composites. This study aims to development of the dissimilar material resistance welding process of thermoplastic CFRP and CFRTP using phenoxy polymer for welding layer.
