Abstract
This invention relates to a black glass fiber which is resistant to oxidation at a temperature of about 1350° C. and has the empirical formula SiCx Oy where x ranges from about 0.5 to about 2.0 and y ranges from about 0.5 to about 2.0. This invention also relates to a process for preparing a black glass fiber comprising reacting a silicon hydride group with a silicon olefinic group in the presence of a hydrosilylation catalyst to give a cyclosiloxane polymer. The polymer is then spun into fiber, hardened and then pyrolyzed to give a black glass fiber.
