In recent years

thermoplastic composite materials have been applied more and more in foreign engineering. Compared with thermosetting composites

thermoplastic composites have the following application advantages: High toughness and damage tolerance

processing features similar to metal

unrestricted shelf life of raw materials

short processing cycle. Especially it has good recycled

recyclable

reusable features

and not environmental pollute features

well adapted to environmental requirements of the proposed material industry in the modern world. This paper introduces the characteristics of matrix and reinforcement materials of thermoplastic composite

common molding methods of thermoplastic composite materials

welding technology

and engineering applications in foreign aerospace and other field

and analyzes the problems encountered in the process of the application of thermoplastic composites and the development direction.
