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.
