Abstract

The structural vehicles are steel members of square or circle tube with definite shape. These members support various components and absorb impact energy to protect passengers during accidentswhen crash happen. Structural members need to be lightweight and stable. In this study, we do an impact simulation of a CFRP square member using finite element analysis program Ls-Dyna in order to predict fracture shape and energy absorb feature of CFRP member. Also, we make square member shape of CFRP and do an impact experiment. We compare the analytical and experimental results and consider the fracture shape and energy features of CFRP members.
