Abstract: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.
