CERAMIC COMPOSITE MATERIAL Russian patent published in 2012 - IPC C04B35/80 C04B35/577

Abstract RU 2447039 C1

FIELD: chemistry.

SUBSTANCE: invention relates to ceramic composite materials and can be used in making heat-loaded assemblies and components of prospective gas-turbine units and engines of gas and oil pumping, transportation and energy systems operating at high thermal cyclic loads at temperatures of up to 1650°C in air and in fuel combustion products. The disclosed ceramic composite material contains carbon fibre and a matrix obtained from a composition having the following chemical composition, wt %: Si 20-35, C 25-40, SiO₂ 5.5-6.0, HfO₂ 5-8, SiC - the rest.

EFFECT: high reliability and longer service life of articles under high thermal cyclic loads at operating temperature of up to 1650°C.
