최적의 압궤특성을 갖는 경량화 구조부재의 개발

The most important objective in designing automobile is currently focus on environment-friendly, safety performance aspect. As for the environment-friendly and economical aspect, the issues are the overall movements toward lightweight automobile production. In this paper, based on the characteristics of square section member, the collapse characteristics and energy absorption capability of hat-shaped section members were analyzed. The axial static collapse tests were performed for each section members. The collapse modes and the energy absorption capability of the each section member were analyzed. The square sectional members which were composed of the aluminum, CFRP and hybrid were used and hat-shaped sectional members which were composed of the CFRP, hybrid were used by the specimens. In the collapse characteristics and energy absorption capability of the each member compared and they were analyzed.
