Abstract:
1. A carbon-ceramic brake disc, comprising: a first frictional surface formed at one side of the brake disc on which a brake pad can be pressed on; a second frictional surface formed at the other side of the brake disc on which a brake pad can be pressed on, wherein the first frictional surface and the second frictional surface are in parallel with each other; a plurality of heat dissipation holes formed penetrating between the first frictional surface and the second frictional surface, wherein each of the heat dissipation holes has an inner surface; and an inclined curved surface formed between an inner surface and the first frictional surface or the second frictional surface in each of the heat dissipation holes, wherein the inclined and curved surface includes an inclined convex-curved surface formed adjacent to the first frictional surface or the second frictional surface and an inclined concave-curved surface formed adjacent to the inner surface, and the inclined convex-curved surface and the inclined concave-curved surface have a predetermined radius of curvature, respectively.
