    Abstract:

    The hybrid structures of metal-composites have been widely used in the field of aerospace, marine and vehicle industry due to the advantages of high specific modulus and high specific strength of aluminum alloy and resin matrix composites. Therefore, the joining technology between metal and composites as one of the crucial problems in these industries has been paid more attention. In this paper, the connection mechanism and influencing factors of the joining processes of resin matrix composites and aluminum alloy are reviewed. At present, bolt connection, rivet connection, adhesive bonding, injection molded direct joining and welding are studied for the connecting between aluminum alloy and resin matrix composites. The processes of bolt connection and rivet connection are simple, however, the stress concentration is easy to produce around the hole. The cost of adhesive bonding is low, but the anti-impact and anti-stripping strength of the interface is low. The production cycle in the process of injection molding direct joining is short, but the strength of the joint is also low. The degree of automation in the welding technology is high, however, the required equipment is expensive. Finally, the development direction of joining technology between aluminum alloy and resin matrix composites that can obtain the joints with high performance and high reliability is pointed out according to the current research results.
