| 摘要 |
The present invention relates to a disc for disc brakes, comprising a support and a braking band suitable to cooperate with brake calipers in order to exert a braking action on a vehicle, said braking band comprising a shaped body extending around a symmetry axis and being laterally defined by braking surfaces, said braking band 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, characterized in that it comprises at least one strengthening ring in carbon-carbon material located near or at the cracking point.
