COMPOSITE LAMINATE AUTOMOTIVE STRUCTURES

摘要

A side impact beam (100) for an automotive body construction has an outer structural portion (102) of mild steel or nonheat-treated high-strength steel, and an inner reinforcement stamping (104) of ultrahigh-strength steel separated by a thin layer of structural foam (106) of thermally expandable resin-based material including hollow microspheres. The inner reinforcement (104) is localized at the midpoint of the side impact beam (100). A vehicle bumper (200) for a motor vehicle has an outer structural portion (202) of mild steel or nonheat-treated high-strength steel, and an inner reinforcement stamping (206) of ultrahigh-strength steel separated by a thin layer of structural foam (208) of thermally expandable resin-based material including hollow microspheres. The inner reinforcement (206) is localized at the midpoint of the vehicle bumper (200).
