Ultrasonic welding of fiber-reinforced thermoplastic composites: a review

Ultrasonic welding is a special joining process with high joining speed and good joint strength. Compared with conventional mechanical and adhesive bonding, ultrasonic welding has many advantages for joining thermoplastic composite. In this paper, the latest advances in ultrasonic welding technology for fiber-reinforced thermoplastic composites were reviewed. This paper not only compares the advantages and disadvantages of the ultrasonic welding process with other welding methods but also discusses the influence of ultrasonic welding parameters on the welding quality. The ultrasonic welding of dissimilar materials was summarized. In addition, the quality inspection and repair of ultrasonic composite welding were also discussed. Finally, the research status and development prospect of ultrasonic welding for thermoplastic composites were analyzed.
