ABSTRACT:
A brake disc of carbon-carbon composite material comprising a substrate of a mixture of carbon fibres of two very different ranges of length and embedded in a carbon matrix. The longer fibres are oriented and distributed randomly in planes approximately parallel to the friction surfaces of the disc, and the shorter fibres are oriented and distributed randomly in the volume of the disc. The brake discs according to the invention are useful in particular in the aviation field. They can be made by ultrasonically molding a mixture of the fibres and a suitable liquid, followed by heat treatment; or by chemical deposition of carbon from the vapor phase.
