적층구성이 CFRP 사이드부재의 압궤특성에 미치는 영향

This study is to investigate the collapse characteristics of CFRP(Carbon-Fiber Reinforced Plastics) side member on static tests. Currently, stacking condition related to the collapse characteristics of composite materials is being considered as an issue for the structural efficiency and safety of automobiles, aerospace vehicles, trains, ships even elevators during collision. In particular, CFRP composite materials have found wide applicability because of their inherent design flexibility and improved materials properties. The most important objective in designing automobiles is Currently to focus on environment-friendly aspect and safety performance aspect. In this study, CFRP side members with single-hat-section shaped were manufactured. The axial static collapse tests were performed for the members using universal testing machine, and the collapse mode and energy absorption capability were analyzed according to stacking condition.
