Carbon-fiber-reinforced silicon-carbide-based composite material
A braking material using a carbon-fiber-reinforced silicon-carbide-based composite material which has better strength and toughness is provided. By using the carbon-fiber-reinforced silicon-carbide-based composite material including a bundle of fibers having chopped carbon fibers arranged in parallel and the other carbon component, carbon, silicon, and silicon carbide, in which the fiber bundle is flat, its cross-section perpendicular to its longitudinal direction has a larger diameter of 1 mm or more, a ratio of the larger diameter to a smaller diameter is from 1.5 to 5, and a plurality of the fiber bundles are randomly oriented substantially along a two-dimensional plane, in a surface layer between at least 500 µm and maximum 4000 µm in depth from the surface, a total content of said silicon carbide and the silicon carbide resulting from silicifying the chopped carbon fibers and the other carbon component is from 50% by weight to 80% by weight, and a two-dimensional side serves as a braking side to thereby constitute the braking material.
