A method for making a composite structure or a portion of structure of a braking band (2) of a brake disc (1), unusually capable of obtaining a structure with an especially long life, comprising at least the following steps: - making a composite ceramic structure, comprising carbon fibre filaments, silicon and silicon carbides, obtaining a body of a braking band (3) comprising at least one braking surface (4); - processing said braking surface removing a surface layer so as to have carbon not bonded with silicon on the surface ; - removing at least partly the carbon not bonded with silicon from the surface; - depositing a protective coating on said braking surface. |
