Abstract: A brake disc manufactured by a method of manufacturing a brake disc according to the present invention includes a carbon fiber Cf, silicon Si, silicon carbide Sic, and a silicon-copper alloy SixCuy. The carbon fiber Cf, silicon Si, carbon C, and silicon carbide SiC make a disc light and provide high thermal shock resistance, anti-oxidation, wear resistance, strength, and friction coefficient. The copper Cu and silicon-copper alloy SixCuy increase heat capacity at constant volume of a disc, so a large increase in temperature of the disc is prevented and a changing range of the friction coefficient is reduced in braking. Accordingly, the brake disc according to the present invention has all of the advantage of a brake disc made of a carbon fiber-reinforced ceramic composites without thermal deformation and deterioration of a pad, a hat part, and a caliper.

Abstract: A carbon ceramic brake disc according to the present invention includes: a support body having cooling channels at the center portion; and friction layers directly attached to the top and the bottom of the support body without a bonding layer and having components different from the components of the support body, in which the support body is composed of a plurality of layers having components similar to the friction layers, gradually toward the friction layers from the cooling channels as the center. Accordingly, the support body can perform thermomechanical shock absorbing that is an original function and the friction layers and the support body can be prevented from separating while the carbon ceramic brake disc is manufactured.
