| 摘要 |
The invention relates to a component such as a brake disc formed of a carbon-based composite with a protective outer layer on the friction surface. The protective outer layer is preferably formed from a ceramic and is selected to provide a friction co-efficient and/or high wear resistance appropriate to the service conditions. The invention allows a wide range of carbon-based substrates to be used in brakes allowing cost and technical efficiency to be optimised. |
