경량화용 Hybrid 사각 복합구조부재의 충돌 거동 평가

In this study, the Hybrid square composite structural members were manufactured using aluminum and Carbon Fiber Reinforced Plastics (CFRP) which are representative lightweight materials. The disadvantages of aluminum and CFRP members were considered to be mutually complimentary while the advantages of each member were combined to exhibit collapse characteristics of effective structural members. Impact axial collapse tests were carried out for the compound members, which comprised an aluminum member externally reinforced by stacking CFRP.
