Abstract:
A process for forming a high temperature oxidation resistant coating on a carbon-carbon composite is disclosed and claimed. The process comprises applying a cyclosiloxane monomer blend containing a filler such as silicon carbide to a carbon-carbon composite, polymerizing and pyrolyzing said blend to form a filled black glass protective coating on the carbon-carbon composite.
Abstract:
Carbon-containing black glass compositions of matter having the empirical formula SiCxOy in which x ranges from about 0.5 to about 2.0, and y ranges from about 0.5 to about 3.0, wherein the carbon content of the black glass ranges from about 10 % to 40 % by weight, are prepared by pyrolysis of a cyclosiloxane polymer in a non-oxidizing atmosphere at a temperature from about 750 DEG C to about 1400 DEG C.
