Abstract: Carbon fiber enhanced thermoplastic composite (CFRTPC) has become a new generation of lightweight material following aluminium, magnesium alloy, and thermosetting composite materials due to its high damage tolerance, high impact resistance, high fatigue resistance, corrosion resistance, re-molding, repair and recyclable. One of the crucial processes in the production and assembly of CFRTPC structures for civil aircraft is connecting manufacturing. Consequently, a multitude of interrelated CFRTPC architectures is studied and developed worldwide. Among these is welding, which has a number of advantages over conventional mechanical and adhesive joining methods. It may be used to join, assemble, and repair damage to CFRTPC constructions. The technology of CFRTPC induction welding is summarized, including the equipment used, the thermal mechanism, the parameters of the welding process, numerical simulation, quality control and evaluation, and other factors. The research results on CFRTPC induction welding are systematically discussed, and common issues are looked forward to. The is study also serves as a reference for large-scale manufacturing, assembly, and damage repair applications of CFRTPC workpieces.
