Continuous carbon fiber reinforced thermoplastic composites exhibit excellent performance and are a typical representative of the new generation of high-end composite materials. European and American countries have mastered the manufacturing technology of high-performance carbon fiber thermoplastic prepregs to varying degrees and established corresponding standardized quality evaluation systems for thermoplastic prepregs. However, due to equipment restrictions and the dual blockade of raw materials and technology imposed by European and American countries on China, the manufacturing technology of continuous carbon fiber thermoplastic prepregs in China has not been improved.

In order to break the technological blockade imposed by Western countries, catch up with advanced international manufacturing levels, and meet the application needs of high-end carbon fiber products in China, the R&D personnel of Hansu New Materials spent 6 years combining theory with practice, fully understanding the viscosity and crystallinity changes of prepreg at various stages, and finding a method to improve the melting between carbon fiber tow and thermoplastic resin, By improving the equipment and controlling the porosity, dimensional stability, and adhesive content of the prepreg, a continuous carbon fiber reinforced thermoplastic unidirectional prepreg product was successfully prepared to meet different needs. From a preliminary 300mm width to 600mm width, then the first appearance of the 1000mm wide PEEK substrate unidirectional tape today, the amount of thermoplastic resin contained is controllable and accurate. The resin can fully penetrate carbon fiber bundles and is evenly distributed, with stable quality and a wide variety. The 1000mm unidirectional tape is also the widest product on the market at present, It can be cut into various widths as needed to produce various types of carbon fiber thermoplastic components, which is a milestone in the development history of the carbon fiber composite industry.
