A disc brake for a vehicle comprising a disc and pads, the disc being rotatable integrally with wheels and the pads capable of being brought into friction engagement with the disc. The disc comprises a baked carbon fiber reinforced carbon composite comprising dispersed bundles of short carbon fibers impregnated with a reinforcing material of primarily a pitch. The pads comprise a baked carbon fiber reinforced carbon composite comprising dispersed bundles of short carbon fibers impregnated with a reinforcing material of primarily a pyrolytic carbon and a thermosetting resin.

Pitch-reinforced carbon fiber brake disc and pyrolytic

The present invention discloses a disc brake for a vehicle having a disc which is rotatable integrally with the wheels and pads which are brought into friction engagement with the disc. The disc is prepared by impregnating a reinforcing material into a carbon fiber reinforced carbon composite obtained by dispersing bundles of multiple single short carbon fibers with primarily a pitch, a combination of a pyrolytic carbon and a pitch or a combination of a pyrolytic carbon and a thermosetting resin, followed by baking; whereas the pads are prepared by impregnating a reinforcing material into a carbon fiber reinforced carbon composite obtained by dispersing bundles of multiple single short carbon fibers with primarily a combination of a pyrolytic carbon and a thermosetting resin or a combination of a pitch and a thermosetting resin, followed by baking.
