The high-quality connection between carbon fiber reinforced thermoplastic composites (CFRTP) and titanium alloy composite structure is the key to realize aircraft lightweight and high-strength manufacturing. In this paper, the laser high-speed rotary welding technology is used to connect the composite structure of CFRTP titanium alloy. By preparing grid micro textures with different sizes on the surface of titanium alloy, the effect of interface state on the strength of CFRTP titanium alloy joint is studied. The results show that the preparation of micro texture on the surface of titanium alloy can significantly improve the strength of the joint, and the micro texture under different wire spacing has a direct impact on the strength of the joint. The smaller the wire spacing, the higher the strength of the joint; Adding PA resin layer between the micro texture of CFRTP and titanium alloy is conducive to the production of high-strength joints.
