Oxidation resistant carbon composites with improved friction performance and methods for making and using them

摘要

An oxidation resistant carbon composite material comprises nanocrystalline silicon carbide regions distributed throughout a carbon matrix. The composite is prepared by intermixing in a solvent a silicon carbide precursor and a carbon precursor and forming a solution that is free of solids. After removing the solvent from the mixture, the remaining material is pyrolyzed and forms the characteristic nanocrystalline silicon carbide in a carbon matrix. A composite made by the subject method and a part made from the composite are also provided.
