The work aims to study the impact of selected materials and structural design of automobile collision avoidance beam on automobile safety. The concept and characteristics of automobile collision avoidance beams were summarized and the impact of different materials and structures of collision avoidance beams on automobile safety was compared. The collision performance of different materials was explored through simulation. Under the optimal structural conditions, the reinforced bamboo fiber composite collision avoidance beam exhibited low displacement and strong repair performance during its collision testing process. The conclusion indicates that reinforced bamboo fiber composite materials have good protection properties. Compared to other traditional materials, reinforced bamboo fiber composite materials have excellent degradable properties and good recyclability, providing good reference suggestions for modern automotive design, which is conducive to the healthy development of the automobile industry and further improvement of the safety performance of the finished automobile.
