“…Lightweight materials such as aluminum alloys and carbon fiber reinforced plastic (CFRP) are extensively utilized in the aerospace industries [1,2]. Given the growing demand for lightweight and structurally integrated aerospace equipment, single CFRP and aluminum alloys face challenges in meeting these requirements [3,4]. Fiber metal laminates (FMLs) are superhybrid materials obtained by alternating layers of fiber composites and metal plates, providing unique structural properties [5].…”

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.
