ceramic matrix composites (rus. композиты с керамической матрицей) — composites with oxide, carbide, nitride or other inorganic non-metallic heat-resistant matrix.

Description

Ceramics are materials with high elastic modulus, high melting point and high hardness. Because of the inherent brittleness of these materials the main problem to be solved while forming composite structures on their basis is to ensure crack resistance. In such composites, including fibre-reinforced, this is usually achieved through the introduction of transitional intermediate layers into the composite structure. In the so-called hard alloys for cutting tools, which have been known for many decades, the role of such an intermediate layer between the ceramic particles is played by a metal "band", which provides the crack resistance of the composite.

Reinforced ceramic matrix composites are used as heat-resistant materials and components of armor elements. Composites filled with micro- and nanoparticles of special additives are used in cutting tools, as wear-resistant materials and dental filling materials. This category does not include composites with polymer, carbon and metal matrices.
