Abstract: Objective The aim is to investigate effects of laser texturing process parameters on micro-texture morphology of aluminum alloy surfaces and to explore their role in regulating mechanical performance of laser bonded joints between aluminum (Al) and carbon fiber reinforced thermoplastic composites (CFRTP). Methods A grid-like micro-texture was prefabricated on the surface of 6061-T6 aluminum alloy by laser texturing technology, combined with laser bonding process to prepare Al-CFRTP lap joints. Influence of laser power, texturing speed, and texturing times on micro-texture morphology was systematically analyzed. The correlation mechanism between texturing parameters and performance of joints was revealed through tensile shear tests and fracture morphology observations. Results When laser texturing power was 50 W and texturing speed was 2 000 mm/s, a uniform micro-texture could be formed on the surface of aluminum alloy. The maximum tensile shear strength of joints reached 5 307.6 N when texture spacing was 0.2 mm and depth was 83.6 μm, achieving a 129% increase compared to the untreated joints. The interfacial bonding primarily relied on mechanical interlocking effect, and fracture modes included CFRTP pull-out, shear fracture, and sub-surface tearing. Conclusion Laser texturing significantly enhances strength of joints by increasing interfacial contact area and mechanical interlocking effect. However, excessive texture depth and spacing may result in insufficient filling or reduced contact area, it is necessary to optimize parameters to achieve optimal performance.
