Carbon fiber-reinforced thermoplastic composites (CFRTP) has emerged as a new generation lightweight structural material, renowned for its exceptional strength-to-weight and stiffness-to-weight ratios, as well as its fatigue resistance. It has become a strategic material in the aerospace industry, replacing traditional metallic mponents. However, due to significant differences in their physical and chemical properties, integrating multiple lightweight materials in production remains a substantial challenge. Recent studies have comprehensively reviewed the advancements in jointing technologies between metals and CFRTP, encompassing jointing processes, mechanisms, and interface control methods. First, the primary jointing processes and recent advancements in metals and CFRTP were introduced. The principles of thermal interface modification were further elaborated, followed by detailed discussions on mechanical and chemical, interface control methods. Finally, the current state of research and key challenges in jointing between metals and CFRTP have been systematically reviewed and summarized. Future directions have been proposed, offering theoretical and technical support for the lightweight design of next-generation aerospace equipment.
