Abstract
A thermal oxidative barrier coating for organic matrix composites includes a bond coat having nano-particles dispersed in a polyimide matrix and 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 coated article may be utilized in gas turbine engine applications, particularly for a flow path duct adapted for exposure to high temperature, oxygen-containing environments.
