알루미늄/CFRP 복합재의 접착강도 향상을 위한 경화방법에 관한 연구

Abstract

This study investigates the effect of curing method on the bonding strength of aluminum/CFRP composites. The surface of aluminum panel was treated by DC plasma. Lap shear tests and T-peel tests were performed based on the procedure of ASTM 906-94a and ASTM D 1876-95, respectively. Test samples were fabricated by using the co-curing method and the secondary curing method. The results showed that the shear strength of test sam­ples made by the co-curing method was 2.5 times greater than that of test samples made by the secondary curing method. The T -peel strength of the co-curing method case was almost 2 times greater than that of the secondary curing method case.
