Abstract
The design of car body structural member aimed to develop members with the optimum impact characteristics to ensure a protected space for passengers in the case of automobile collisions. Accordingly, these members were fabricated to provide sufficient rigidity and safety to the passenger room structure and to absorb large amounts of energy during collision. CFRP(Carbon Fiber Reinforced Plastics) of the advanced composite materials as structure materials for vehicles, has a widely application in lightweight structural materials of air planes, ships and automobiles because of high strength and stiffness. In this study, impact collapse characteristics and collapse modes were quantitatively analyzed according to the changes in section shape(square, single and double-hat shaped section) and stacking angles([+15°/-15°]4,[+45°/-45°]4, and [90°/0°]4). This analysis was performed to obtain design data that can be applied in the development of optimum lightweight members for automobiles.
