Resistance welding technology of fiber reinforced polymer composites: a review

Recently resistance welding (RW) technique have emerged as a viable alternative method for the joining of fiber reinforced polymer (FRP) composites. It is more cost-efficient as opposed to the conventional adhesive, mechanical and other joining methods. The objective of this paper is to provide a deeper insight into the recent development of the resistance welding technique for FRP composites. The main focus is set on the parameters that govern the welding process and the principal phenomena that affect the joints of the thermoplastic composite. The evaluation methods, the comprehensive failure modes, welding interface behavior and microscopic evaluation of interface are also looked at in detail. And this technology has been further extended to the connection of thermoset composites. In addition, several alternative fresh implants that involve micro-nano carbon materials and offer possibilities for future applications are systematically compared. Continuous resistance welding (CRW) is briefly introduced as one of the most promising methods in the end.
