Abstract
Composite material with matrix and reinforcing fibres of carbon and its production process. The composite material according to the invention comprises a substrate (2) of carbon fibres covered with a fine silicon carbide coating (6) and embedded in a carbon matrix (4) containing 2 to 10% by weight silicon carbide, an outer silicon carbide covering (10), followed by a first filling of the cracks with silica (14) and a second filling with borosilicate glass (16) (SiO.sub.2 -B.sub.2 O.sub.3). This unoxidizable material can in particular be used as a heat shield for a spacecraft.
