MCMB-based laser 3D printing Cf/SiC composite material and preparation method thereof
The invention relates to a laser 3D printing Cf/SiC composite material based on MCMB and a preparation method thereof. The preparation method of the Cf/SiC composite material comprises the following steps: carrying out dry ball milling on short carbon fibers, silicon carbide, an organic binder and mesocarbon microbeads MCMB to obtain Cf/SiC/MCMB composite powder, carrying out laser 3D printing molding to obtain a porous Cf/SiC printed body, and finally carrying out degreasing and siliconizing sintering to obtain the Cf/SiC composite material. Wherein in terms of 100 vol% of the total volume of the Cf/SiC/MCMB composite powder, the volume ratio of the short carbon fibers is 5-65 vol%, the volume ratio of the silicon carbide is 15-75 vol%, the volume ratio of the organic binder is 15-30 vol%, and the volume ratio of the mesocarbon microbeads is 5-40 vol%.
本发明涉及一种基于MCMB的激光3D打印Cf/SiC复合材料及其制备方法。所述Cf/SiC复合材料的制备方法包括：将短切碳纤维、碳化硅、有机粘结剂和中间相碳微球MCMB干法球磨得到Cf/SiC/MCMB复合粉体，再经激光3D打印成型得到多孔Cf/SiC打印体，最后经脱脂和渗硅烧结，得到所述Cf/SiC复合材料；其中，以所述Cf/SiC/MCMB复合粉体总体积为100vol％计，短切碳纤维体积占比为5～65vol％，碳化硅体积占比为15～75vol％，有机粘结剂体积占比为15～30vol％，中间相碳微球体积占比为5～40vol％。
