Abstract

Scanning electron microscopy is used to study the structure and failure process of “carbon—carbon” composites under the action of flows of gas containing oxygen. Failure is shown to be caused by the successive oxidation of the carbon matrix and the reinforcing fibers, giving rise to the collapse of the bond between the matrix and the fibers and, thus, to a weakening of the composite. Ways of increasing the heat resistance of the composites by building up an additional heat-resistant coating on the surface of articles made of the composites is proposed.
