Resin based Carbon fiber reinforced plastics (CFRP), as the cutting-edge light-weight composite material, are widely used in the aerospace parts. The main technologies to bond CFRPs and metals are namely adhesive bonding and mechanical bonding, which includes limitation in some area . However, laser welding technology possesses the advantages of low heat input and small deformation after welding, therefore, it can be applied to the bonding of composites and metals. This paper reviewed the bonding mechanisms and the joint defects of the joints between the CFRP materials and the common used metal like aluminum alloys, titanium alloys and carbon steels by laser welding process, and analyzed the effect of welding process, structural optimal and pre-surface treatment on the property of joint, Finally, the prospect of the CFRP/metal joint formed by laser welding are presented in this paper.
