Abstract
A review of the research progress on composite materials in automotive components,using the bumper anti-colli-sion beam as an example,was conducted to promote their application.The material and structural design of composite anti-collision beams,as well as the research progress on the connection of internal parts of bumpers,were summarized.Progress in research on carbon fiber,glass fiber,natural fiber,and other composite materials in automotive anti-collision beams were briefly described.The influence of different structural composite anti-collision beams on crashworthiness performance was introduced,and the advantages and disadvantages of different connection methods for internal parts of bumpers were analyzed.Finally,future directions for the development of automotive composite anti-collision beams were proposed,including the development of new types of composite materials,optimization of anti-collision beam structures,and research on new connection methods.
