차체 경량화용 CFRP 박육부재의 충돌압궤특성

Abstract

Important issues in the design of the vehicles could be represented such as reducing CO2 emissions and improving the fuel economy. However, vehicle safety is ensured in a state in which the design is to reduce the weight of vehicle weight reduction for the wings to be made. In this study, a representative of lightweight material CFRPs (carbon fiber reinforced plastic), thin-walled members using the CFRPs were studied after the collapse crash. Also, experimental investigations are carried out for the CFRP thin-wall member and in order to study the effect of various stacking condition. Static and impact collapse tests were performed with change of the interface numbers, such as fiber orientation angle. Collapse modes and energy absorption characteristics had been analyzed.
