The utilization of lightweight materials like aluminum alloys and carbon fiber-reinforced plastic is an effective approach to achieving weight reduction in aerospace applications. Fiber metal laminates (FMLs) are superhybrid composite materials characterized by heterogeneous interfaces such as metal-resin and fiber-resin. Significant variations in the physical and chemical properties among different materials result in poor interfacial mechanical properties. An advanced method of ultrasonic vibration assisted hot press forming (UAHPF) of FMLs is proposed to improve the mechanical properties. FMLs were fabricated by UAHPF using the specially designed and manufactured forming tool. Mechanical properties were tested, and optimal process parameters were determined using the Criteria Importance Through Intercrieria Correlation method. The mechanism underlying the strengthening behavior of UAHPF was elucidated. The results demonstrated that the optimal parameters increased the tensile strength, bending strength, and shear strength of the FMLs by 13.09%, 11.97%, and 49.51%, respectively. Appropriate utilization of ultrasonic vibration during hot pressing could mitigate prepreg bubbles, lower the surface contact angle, and enhance fiber density. In comparison to autoclave forming, UAHPF markedly diminished internal defects in FMLs, augmented the metal-fiber contact area, and narrowed the width of the fiber-resin gap. This novel process is a convenient and effective way to enhance the interfacial properties, which can provide potential an idea for the performance enhancement of aerospace critical FMLs components.

Aiming at the defects such as delamination and tearing that are prone to occur in the drilling process of Carbon Fiber Reinforced Plastic (CFRP), the finite element simulation and experimentation researches on drilling were carried out by using the Ultrasonic Vibration-Assisted Drilling (UVAD). In this paper, the kinematics characteristics of drill cutting edge during UVAD were analyzed to reveal the basic principle of UVAD. Then the most representative 0° and 90° angle lay-up CFRP of UVAD finite element simulation drilling model was established based on Hashin failure criterion and kinematics characteristics of UVAD. Finally, combined with drilling experiments, the accuracy of the finite element model was checked and the influence of process parameters on the cutting force was explored, and the removal mechanism of UVAD was revealed. The simulation results show that, compared with the Conventional Drilling (CD), the cutting force was reduced and removal modes was changed with the high-frequency impact cutting capability by UVAD. The experimental results also further demonstrate that UVAD effectively reduced the axial force and the delamination ratio. Specifically, the axial force during drilling was reduced by 5.1%~18.2%, the delamination factor at the hole outlet was decreased by 3.1%~8.2%, the drilling defects at the outlet were effectively suppressed, and the quality of the holes was significantly improved.
