ABSTRACT:
An oxygen resistant high temperature composite structure comprises a carbonous matrix and reinforcing high temperature fibers disposed within said matrix, an outer refractory coating covering said matrix, boron, in elemental form and/or as a moiety of a compound dispersed throughout said structure, silicon, in elemental form and/or as a moiety of a compound dispersed throughout said structure, and titanium, in elemental form and/or as a moiety of a compound dispersed throughout said structure, said silicon and said boron oxidizing when exposed to a high temperature, oxidizing environment to form silicon oxide and boron oxide, and said titanium forming titanium oxide which stabilizes the molten phase of the boron oxide. Microcracks which form in the refractory coating are sealed by a molten glass which forms from oxidation of the boron, silicon and titanium, thereby preventing oxidation degradation of the underlying matrix.
