Abstract
A carbon-carbon composite material formed from a fibrous substrate and a matrix. The fibrous substrate has a carbon fiber base which acts as a reinforcement, a coarse texture and large sized cavities. The matrix includes pyrocarbon layers coating the fibrous substrate and a carbon based cellular structure dividing the large sized cavities of the substrate into small cavities having open porosity.
