Abstract
Refill friction stir spot welding (RFSSW) is applied in various industrial areas. Herein, we developed a hot-pressing post-treatment method for improving the shear strength of an Al 1060–carbon fiber–reinforced plastic joint by >40%. The strengthening effect of the hot-pressing treatment was based on the reinforced micro-mechanical interlocking mechanism and the infiltration of melted thermoplastic epoxy into the Al layer. Exploring such a high-strength joint made of dissimilar materials would open a novel route for RFSSW process design.
