Review on Joining Process of Carbon Fiber-reinforced Polymer and Metal: Applications and Outlook

Abstract:

The hybrid structure of composite material such as carbon fiber-reinforced polymer (CFRP) and metal such as steel, aluminum alloy or titanium alloy is an effective structure to realize lightweight with reliable structural strength. The CFRP-metal hybrid structure is widely used in aircraft, automobile and watercraft. The CFRP-metal joints joined by plastic deformation are characterized by lightweight and high-strength, which are suitable for various working environments. Thus, the advanced joining method based on plastic deformation has a good application prospect. The application of various joining techniques between CFRP and metal, as well as the strength of hybrid joints, was reviewed. Some future researches and developments of CFRP-metal hybrid joints with high-performance, light-weight and high-reliability were highlighted.
