Abstract

In this study, the effect of surface treatment of CFRP (Carbon Fiber Reinforced Composites) on the shear strength of CFRP/metal composites was investigated. The surface of 14 plied unidirectional (0-dog ) CFRP was treated by an $Ar^{/}$ + ion beam under an oxygen environment. Shear strength tests were performed using SLS (Single Lap Shear) specimens based on the ASTM D906-94a procedure. The shear strength of the surface-treated CFRP/metal composites was compared with that of the untreated CFRP/metal composites. The results showed that the shear strength of surface-treated CFRP/metal composites was 36% greater than that of untreated CFRP/metal composites.
