Method for preparing composite carbon fiber material, composite carbon fiber material and application
The invention relates to the technical field of carbon fiber composite materials, and discloses a method for preparing a composite carbon fiber material, the composite carbon fiber material and application. The method comprises the following steps: impregnating carbon fibers with an organic silicon dispersion liquid, curing the carbon fibers, and carrying out heat treatment to obtain a composite carbon fiber material; wherein the organic silicon dispersion liquid contains an organic silicon polymer and reinforcing particles; the reinforced particles are selected from at least one of silicon dioxide, silicon carbide, boron carbide, graphite and boron nitride. According to the method, the organic silicon dispersion liquid containing reinforced particles is used for dipping the carbon fibers, the film-forming property of the organic silicon dispersion liquid on the surfaces of the carbon fibers can be improved, and meanwhile, the organic silicon dispersion liquid and an organic silicon polymer are subjected to high-temperature co-melting synergistic interaction during heat treatment, so that the prepared composite carbon fiber material is not prone to cracking, and a surface coating is not prone to falling off; and the material has relatively strong oxidation resistance and relatively high tensile strength.
