    摘要: This invention relates to a black glass fiber which is resistant to oxidation at a temperature of about 1350.degree. C. and has the empirical formula SiC.sub.x O.sub.y 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.

    摘要: A fiber reinforced glass composite capable of absorbing or transmitting microwave radiation includes refractory fiber in a matrix of a black glass ceramic having the empirical formula SiCxOy where x is greater than zero and up to about 2.0, and y is greater than zero and up to about 2.2. Preferably, the black glass ceramic is made by pyrolyzing precursor polymers derived from cyclosiloxane monomers containing a vinyl group attached to silicon and/or a hydride-silicon group in a controlled atmosphere, thereby adjusting the dielectric properties.
