Abstract
A disk brake disk comprises a braking band for cooperating with brake calipers in order to exert a braking effect on a vehicle. The braking band of one embodiment comprises a shaped body which extends about an axis of symmetry and is defined laterally by braking surfaces, and the shaped body is made of a composite material which, according to one embodiment, is produced by causing a mixture comprising bundles of filaments constituted substantially by carbon, arranged randomly and having dimensions no greater than 30 mm, to interact with silicon at a temperature high enough to bring about fusion of the silicon. According to this embodiment, the shaped body has a plurality of reinforcing fibers incorporated in the shaped body and extend around the shape fo the shaped body in a manner such as to deter the propagation of cracks.
