High-performance thermoplastic composites have great potential for structural weight reduction because of their excellent performance in impact resistance and damage tolerance. Due to its weldability in processing, thermoplastic composites are recyclable and reusable, which is an important way to achieve the green development of aviation structure and contribute to the reduction of aviation carbon emissions. This work summarized the key technologies in the application of high performance thermoplastic composites such as prepregs technology, molding technology, welding technology as well as automation equipment and processing. The development status of thermoplastic composite structure researches for civil aircraft were reviewed. The main influencing factors, development trend and application prospective of these key technologies were analyzed. According to the characteristics of manufacturing process of thermoplastic composites, the applicable objects of different manufacturing processes were analyzed, and the suggestions for the process selections of thermoplastic composite main structures of civil aircraft was proposed.
