Composite laminate automotive structures

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