[0002] Fiber reinforced thermoplastic resin (FRTP) is a composite material that combines fiber material with thermoplastic resin. This material is widely used in aerospace, automobile, construction and other fields due to its excellent physical and mechanical properties. Fiber reinforced thermoplastic resin is becoming an important material choice in many industrial fields due to its excellent performance and processing convenience. With the advancement of technology and the improvement of processing technology, the application prospects of FRTP will be even broader.

[0003] In the existing fiber-reinforced thermoplastic resin prepreg process, a single-sided impregnation method is often used to treat the fibers to achieve the fiber reinforcement effect. However, this method may not only lead to uneven fiber coating, thereby reducing the overall quality of the prepreg, but also has high requirements for controlling the resin viscosity, which makes it difficult for the liquid resin to fully penetrate into the interior of the fiber, thereby affecting the efficiency and quality of the prepreg. To this end, we propose a fiber-reinforced thermoplastic resin prepreg impregnation device. Utility Model Content
