Reinforced silicon carboxide composite with boron nitride coated ceramic fibers

An improved fiber reinforced glass composite includes a boron nitride-coated refractory fiber in a matrix of a black glass ceramic having the empirical formula SiCxOy where x ranges from about 0.9 to 1.6 and y ranges from about 0.7 to 1.8. Preferably the black glass ceramic is derived from cyclosilo...

More Information
Summary:An improved fiber reinforced glass composite includes a boron nitride-coated refractory fiber in a matrix of a black glass ceramic having the empirical formula SiCxOy where x ranges from about 0.9 to 1.6 and y ranges from about 0.7 to 1.8. Preferably the black glass ceramic is derived from cyclosiloxane monomers containing a vinyl group attached to silicon and/or a hydride-silicon group. Graceful failure can be obtained after exposure of the composites to temperatures up to 600 DEG -700 DEG C. in air.
