[0002] Fiber-reinforced thermoplastic resin prepreg equipment is a key piece of equipment used to manufacture fiber-reinforced thermoplastic composites. Fiber-reinforced thermoplastic composites (FRTPs) have broad application prospects in aerospace, automotive, and sporting goods fields due to their unique properties, such as high strength, high toughness, good fatigue resistance, and reproducibility.

[0003] In existing technologies, fiber thermoplastic resin pre-impregnation devices often involve multiple processes. The surface of the impregnated fibers still has undried resin, making it impossible to manufacture the Pike racket in a timely manner. Furthermore, the long transport route may cause the thermoplastic resin to slide on the fibers during transport, resulting in uneven resin distribution. This can lead to pores and internal stress in the fiber laminate of the Pike racket, which can affect the mechanical properties and durability of the racket and waste resources.
