The application of composite materials in automobile door anti-collision beams is gradually becoming a key technology to improve vehicle safety. As an important part of the automobile collision safety system, the performance of door anti-collision beams is directly related to the lives of drivers and passengers. Traditional metal materials are gradually being replaced by lightweight and high-strength composite materials due to problems such as heavy weight and insufficient impact resistance. This paper focuses on the advantages and challenges of composite materials in the design of door anti-collision beams, including material selection, structural optimization, and production processes. By comparing and analyzing the mechanical properties of different types of composite materials, the actual application effects in door anti-collision beams are studied, and corresponding design suggestions are put forward. Composite materials can not only effectively reduce the weight of the door but also provide better energy absorption effect during collisions, thereby enhancing safety performance.
