AI Technical Summary
In existing technologies, laser welding joints between metal plates and fiber composite materials have low bonding strength, long processing time, and complex processes, making it difficult to achieve efficient and reliable connections.
Defect structures are constructed on the surface of a metal plate by laser pretreatment under oxygen-containing conditions, and laser welding is performed under oxygen-free and pressure conditions to form a high-strength super-hybrid joint. A two-stage interlocking structure is used to enhance the interfacial bonding.
It significantly improves the load-bearing capacity of metal-fiber composite material joints, simplifies the process, improves processing efficiency, and eliminates the need for additional resin intermediate layers or chemical modification treatments.
