Silicon carboxide composite reinforced with ceramic fibers having a surface enriched in boron nitride |
| abstract |
An improved fiber reinforced glass composite includes a boron-containing refractory fiber having its surface enriched with boron nitride in a matrix of a black glass ceramic having the empirical formula SiCxOy where x ranges from about 0.5 to about 2.0, preferably 0.9 to 1.6 and y ranges from about 0.5 to 3.0, preferably 0.7 to 1.8. Preferably the black glass ceramic is derived from cyclosiloxane or non-cyclic siloxane monomers containing a vinyl group attached to silicon and/or a hydride-silicon group. The boron nitride-containing fiber is the product of treating the boron-containing fiber with ammonia at a temperature between about 1125 °C and 1250 °C. Fibrous failure rather than brittle fracture under stress can be obtained. In one embodiment, composites may be oxidized in air at temperatures of up to 800 °C for 5 to 200 hours to improve the stress-strain properties. |
