ABSTRACT:
Carbon-carbon composites are prepared to receive a subsequent protective coating by having a thin layer (1 to 5 mils) of pyrolytic graphite applied to its surface. The graphite layer improves the performance of subsequent protective coatings and is especially useful on carbon-carbon composites having a positive coefficient of thermal expansion.
