| 摘要 |
<p>The present invention relates to a disc (20) for disc brakes, comprising a support (15) and a braking band (5) suitable to cooperate with brake calipers in order to exert a braking action on a vehicle, said braking band (5) comprising a shaped body (6) extending around a symmetry axis and being laterally defined by braking surfaces (3,4), said braking band (5) being made of composite material which can be obtained by the interaction of a mixture, comprising filament rovings, essentially consisting of carbon, which are randomly arranged and have sizes which are not greater than 30 mm, with silicon at a temperature sufficient to cause the melting of said silicon, and further comprising at least one strengthening ring (2a,2b) in carbon-carbon material located near or at the cracking point.
