摘要

碳纤维增强热塑性复合材料（CFRTP）与钛合金复合结构的高质量连接是实现飞机轻量化以及高强度制造的关键。采用激光高速旋转焊接技术进行CFRTP/钛合金复合结构的连接，通过在钛合金表面制备不同尺寸网格型微织构研究了界面状态对CFRTP/钛合金接头强度的影响规律。结果表明，钛合金表面微织构的制备可以显著提升接头强度，且不同线间距下的微织构对接头的强度有直接影响，线间距越小，接头强度越高；在CFRTP与钛合金微织构中间添加PA树脂层，有利于提高接头强度。

Abstract

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.
