However, many carbon fiber products will crack after high-temperature molding, and if all of them are scrapped, the production cost will be greatly increased
If the method of soil filling is adopted, the impact strength of carbon fiber products after soil filling cannot be guaranteed
In addition, the soil filling process is relatively complicated, which will increase additional labor intensity and cause low production efficiency

Abstract
The invention provides a polymer film for processing a carbon fiber. The polymer film consists of the following components in parts by weight: 30-40 parts of epoxy resin, 15-25 parts of phenolic epoxy resin, 5-10 parts of nitrile rubber, 20-30 parts of butanone, 5-10 parts of dicyandiamide. 1-3 parts of accelerant, 3-5 parts of white carbon black, 2-3 parts of carbon black and 3-6 parts of amine room-temperature curing agents. According to the polymer film produced by the invention, the strength and the toughness of carbon fiber products can be improved. The polymer film comprises various high-strength polymer composite materials and has the advantages of excellent impact resistance and favorable compatibility and combining performance with an epoxy resin system. When the polymer film is in use, the change of original processing conditions is avoided and the surface of carbon fiber cloth is coated with a layer of film. The polymer film is simple and convenient in use and has a wide application prospect.
Description
technical field [0001] The invention relates to the field of processing carbon fiber products in sporting goods, in particular to a polymeric film for carbon fiber processing. Background technique [0002] Carbon fiber products are widely used as processing raw materials in sporting goods. At present, in the field of processing carbon fiber products in sporting goods, there is generally a problem of uneven fluidity of the resin during the molding process of carbon fiber products, which causes the surface of the formed carbon fiber products to crack, and causes surface defects and pinholes. These problems have seriously reduced the impact strength of carbon fiber products. [0003] Many enterprises adopt the method of scrapping severely cracked products, and use the method of filling soil and polishing for products with surface defects. However, many carbon fiber products will break after high-temperature molding, and if all of them are scrapped, the production cost will be...
