Abstract
The present invention concerns a shaped composite material and a method for producing it. More specifically, the invention concerns a disc for a disc brake made from ceramic composite materials, usually known as “CMC”, i.e. “Carbon Material Ceramic” or “CCM”, i.e. “Carbon Ceramic Material”. These materials consist of carbon matrices containing carbon fibres usually infiltrated with silicon and a product of reaction between C and Si, silicon carbide (SiC). More specifically, the invention concerns a shaped composite material comprising a inner layer (3; 103) of CCM C/SiC/Si material comprising disorderly short filaments consisting mainly of carbon and respective outer layers (2, 2′; 102, 102′) of C/SiC/Si material and having an orderly fabric structure of mainly carbon fibres.
