Inorganic oxide resins for internal oxidation inhibition of carbon-carbon composites

摘要

Disclosed is a liquid, boron-containing, inorganic oxide resin containing unsaturated organic groups. The resin can additionally comprise the units &Brketopenst;M-O&Brketclosest;, where M can vary from one unit to the next and is selected from Si, Ti, Al, Ba, Zr, Li and Hf. Also disclosed is a process for inhibiting the oxidation of carbon- carbon composites by impregnating the composite with such resins, cross- linking the resin and pyrolyzing to convert the resin to a ceramic material.
