Abstract
Methods for forming thermal oxidative barrier coatings for organic matrix composites include applying a bond coat having nano-particles dispersed in a polyimide matrix to a hot side surface of a component and overlying the bond coat with a thermal barrier layer comprising a silsesquioxane or an inorganic polymer. The nano-particles may include clay platelets, graphite flakes or a polyhedral oligomeric silsesquioxane. The bond coat may be applied as a liquid. The thermal barrier layer may be applied as a liquid, film, prepreg, molding compound, or a spray.
