Abstract

Abstract : The global demand for reduction in the weight of automobiles has led many countries to focus on the development of hybrid, eco-friendly and electric cars. A reduction in the weight of materials can both increase fuel efficiency and maximise automobile performance. In this study, carbon fibre reinforced plastic members with double-hat cross-sections were manufactured. Impact crushing tests were performed with changes in the stacking conditions such as variations of stacking angles and interface numbers. The impact crushing mode and absorbed energy were quantitatively analysed according to the changes in the stacking conditions. This analysis was performed to obtain design data that can be applied in the development of optimum lightweight members for automobiles.
