✦ Synopsis


Carbon-carbon composites made from ex-acrylic fibres and pyrocarbon matrices have been gasified in air in order to investigate their resistance to oxidation. The carbon fibres and the surrounding pyrocarbon layers are preferentially oxidized due to a catalytic process. The importance of the catalytic phenomenon depends primarly on the heat treatment of the composites. Lowest oxidation rates are obtained after heat treatment at 2900K. Oxidation tests allow a simple evaluation of the carbon-carbon composites performance at the laboratory scale.
