Textured silicon carbide whisker reinforced ceramic matrix composite material based on 3D printing technology and preparation method of textured silicon carbide whisker reinforced ceramic matrix composite material
The invention relates to a textured silicon carbide whisker reinforced ceramic matrix composite based on a 3D printing technology and a preparation method of the textured silicon carbide whisker reinforced ceramic matrix composite, and belongs to the technical field of composite ceramic additive manufacturing. Silicon carbide whiskers are added into 3D printing ceramic slurry, and the step of scraping by a scraper in a photocuring process is applied to a directional arrangement template, so that the silicon carbide whiskers are directionally arranged in ceramic, internal texturing of the whiskers is realized, and a pearl layer bionic structure is obtained. The silicon carbide crystal whiskers and the bionic layered structure have the effects of crystal whisker pulling out, crack deflection, bridging and the like, the excellent performance of the silicon carbide crystal whiskers is promoted to be brought into full play, obvious performance preferred orientation of strength and toughness is kept, and the comprehensive mechanical performance of the material is improved. The preparation process is simple and efficient, the method is suitable for printing forming of precise and complex parts, preparation of high-precision and complex-structure large-size ceramic parts is facilitated, and the formed parts have the mechanical property advantages of high strength and high toughness.
