An oxidation resistant fiber-reinforced composite is made by impregnating a fibrous material with a resin containing a linear polymer having a repeating unit with at least one carboranyl group, at least one silyl or siloxyl group and at least one acetylenic group. The linear polymer may then be cured to form a fiber-reinforced thermoset or may be pyrolyzed to form a fiber-reinforced ceramic. For additional protection of the fibrous material against oxidation, the fibrous material may be prewetted or coated, also with a linear polymer containing a linear polymer having a repeating unit with at least one carboranyl group, at least one silyl or siloxyl group and at least one acetylenic group, prior to being impregnated. The coating on the fibrous material may be cured to form a thermoset coating on the fibers or may be pyrolyzed to form a ceramic coating on the fibers.
