ABSTRACT:
In a process for manufacturing a carbon-carbon component, in particular a brake disk, a porous substrate in the shape of a brake disk (32) is formed exclusively from carbon fibres. Holes (34), whose axes are parallel to the axis of rotation (36) of the disk, are made in the substrate and are arranged on concentric circles (38) centered on said axis of rotation. Areas (42) free of holes are provided around keyways (40) in the disk. The substrate is then compregnated by CVD. The holes in the substrate reduce the path of the gas in the substrate.
