차량구조부재의 경량화소재 적용을 위한 Hybrid 부재의 흡수에너지 특성 연구
A Study on Absorption Energy Characteristic of Hybrid Member for Lightweight Material Application of Vehicle Structural Part
In this study, the square members which were composed of the aluminum. And the hat- shaped members composed of CFRP and hybrid were used as the specimens. On the lightweight design aspect, the collapse characteristic and energy absorption capability of the each member were analyzed and compared. As the result of this study, the collapse mode of square aluminum member was mixed as axially symmetric and asymmetric mode. The energy was absorbed as the stable collapse mode. The energy was absorbed as the stable collapse mode. The square CFRP and the hat- shaped member became unstable due to the brittle failure with the folding mode. The square hybrid member was stably collapsed with compound folding mode combined two modes. The hat-shaped hybrid member was collapsed with compound mode combined outer CFRP hat-shaped member was collapsed stably by entering the fiber in the folding of square aluminum member and fragmentation mode of CFRP.
