Carbon/Carbon Composites Coated with SiC by Chemical Vapor Deposition

Oxidation-resistant carbon/carbon (C/C) composites were fabricated by chemical vapor deposition (CVD) of SiC on the surface of C/C composites; the latter were densified in preforms of carbon cloth lay-up by chemical vapor infiltration (CVI) of carbon. The mechanical properties, thermal properties, and the oxidation resistant properties in air of the material are studied.
