Abstract

Graphical abstract: Highlights: The high speed rotational laser welding technology is introduced to join the CFRTP and the aluminum alloy. The numerical model of CFRTP/Al alloy high speed rotational laser welding was established. The CFRTP/Al alloy joint strength can be predicted by using the numerical simulation method. Abstract: To reduce the defects in laser welding of carbon fiber reinforced polymer (CFRTP) and aluminum (Al) alloy and improve the mechanical properties of the joint, a high speed rotational laser welding (HSRLW) technology was introduced. The mathematical model of CFRTP-Al alloy laser joining was established and the temperature was simulated. The weld depth of aluminum alloy and the penetration depth of CFRTP/aluminum alloy joint were calculated and compared with the experimental result. It was found that the pore defects can be significantly reduced, and a high strength joint could be obtained. The simulation results agree well with the experimental results, and the strength of the CFRTP/aluminum alloy joint can be predicted by using the numerical simulation method.
