Abstract

The invention relates to a carbon fiber treatment method and a product thereof. The method comprises the following steps: (1) stacking carbon fiber prepreg into a carbon fiber layer structure which comprises an external surface and an internal surface; (2) cutting out a resin film which is matched with the carbon fiber layer structure in size and thickness; (3) stacking the resin film on the internal surface of the carbon fiber layer structure; (4) laminating the carbon fiber layer structure and the resin film stacked on the carbon fiber layer structure; (5) after lamination, placing the carbon fiber layer structure and the resin film in a hot pressing die for hot-press forming; (6) after hot-press forming, opening the die and taking out the carbon fiber product. The product is produced after being treated by the carbon fiber treatment method. The carbon fiber treatment method and the product thereof, provided by the invention, can correct deformation of a carbon fiber product during hot-press forming.

Description

【Technical field】 [0001] The invention relates to a processing method of carbon fiber, in particular to a processing method and a product thereof for correcting deformation of carbon fiber during hot pressing. 【Background technique】 [0002] Due to the advantages of light weight, high strength, and good rigidity, carbon fiber is widely used in many industrial and consumer product fields such as aerospace industry, automobile industry, and 3C electronics industry. [0003] Generally, carbon fiber is impregnated with epoxy resin in the carbon fiber layer to make the surface slightly viscous, and then molded into the desired product shape through a mold with high pressure and high temperature in one or several layers, so as to obtain a product with excellent rigidity. carbon fiber products. However, carbon fibers are easily deformed by the lamination direction, hot-pressing conditions, and curing conditions during the hot-press forming process. see figure 1 as shown, figure...
