Abstract

The invention discloses a novel carbon fiber processing method. The method specifically includes the following operation steps of S1, mixing and gluing, wherein resin and a thermosetting adhesive areevenly stirred and mixed in a vacuum mixing tank, and then the surfaces of carbon fibers are coated with the mixed solution through a gluing machine; S2, sizing, wherein the glued carbon fibers are placed in a mold and subjected to hot pressing for 20-30 seconds at the temperature of 220-230 DEG C for forming; S3, shaping, wherein transparent resin powder is evenly scattered on the surfaces of theformed carbon fibers, and then the carbon fibers are placed in the mold for hot pressing at the high temperature of 250 DEG C; S4, secondary sizing. According to the method, a carbon fiber fabric issubjected to gluing firstly through the gluing machine, under the high-temperature condition, the carbon fiber fabric can be rapidly sized in the mold, and then the transparent resin powder is scattered on the sized carbon fiber fabric again for high-temperature shaping so that grain inclination of the carbon fiber fabric can be effectively prevented, the product quality is improved, the operationis simple and short in consumed time, and clean and attractive carbon fiber workpieces can be quickly obtained.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber processing, and in particular relates to a novel carbon fiber processing method. Background technique [0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber containing more than 95% carbon. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber, and undergoing carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside", lighter than metal aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus. It is an important material in national defense and civilian applications. It not only has the inherent intrinsic characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers. When traditional ca...
