Abstract

A method of protecting carbon/carbon composites against oxidation at high temperatures is disclosed. This comprises coating the composite with a hybrid metal alkoxide/organosilicon polymer. The hybrid polymer is prepared by a method comprising mixing an organosilicon polymer having a plurality of Si-H functional groups with a sufficient quantity to undergo a hydrosilylation reaction of a metal alkenoxide, wherein the metal alkenoxide comprises a metal, metalloid or silicon alkoxide containing at least one alkenoxy group; and initiating the hydrosilylation reaction to form the hybrid polymer.
