Abstract

The invention discloses a high-strength and high-toughness ceramic composite and preparation thereof. The ceramic composite is prepared from raw materials in parts by weight as follows; 35-45 parts of nano titanium carbide, 30-40 parts of nano titanium nitride, 25-35 parts of nano silicon carbide, 5-15 parts of calcite powder, 5-15 parts of modified nano illite, 8-12 parts of deionized water, 6-10 parts of mineral oil, 3-5 parts of a saline coupling agent KH560 and 2-4 parts of fumaric acid; a preparation method of the modified nano illite comprises steps as follows: 60-80 parts of nano illite by weight are placed in a glacial acetic acid solution with the mass fraction being 20%-30% to be soaked for 3-5 h, taken out, washed to be neutral and dried at 50-60 DEG C until the moisture content is 3%-5%; 4-6 parts of castor oil are added and evenly mixed, 3-5 parts of dimercaprol and 1-3 parts of nano graphite powder are added, mixing and grinding are performed, and the mixture is sieved by a 200-mesh sieve, and the ceramic composite is prepared. The ceramic composite has high hardness, strength and toughness, and the preparation method is simple.

Description

Technical field [0001] The invention belongs to the field of materials, and specifically relates to a high-strength, high-toughness ceramic composite material and preparation thereof. Background technique [0002] Composite materials usually have good comprehensive properties in which different materials complement each other's strengths. Composite materials have the characteristics of two or more materials and can improve the performance of a single material, such as increasing strength, increasing toughness, and improving dielectric properties. Ceramic composite materials used as high-temperature structural materials are mainly used in aerospace, military and other sectors. In addition, various ceramic composite materials are widely used in the fields of machinery, chemical industry, and electronic technology. [0003] Ceramic matrix composite material is a kind of composite material that is composited with various fibers with ceramic as the matrix. The ceramic substrate can b...
