Abstract
A tailorable polyimide resin system may be used to form an organic matrix composite (OMC) structure for use in high temperature applications. A thermal oxidative barrier coating on the OMC may include a bond coat comprising a tailorable polyimide resin system. The bond coat may include nano-particles such as clay platelets, graphite flakes or a polyhedral oligomeric silsesquioxane. The coating system may include a thermal barrier layer including a silsesquioxane or an inorganic polymer. The tailorable polyimide resin system includes first and second independent prepolymer components able to impart desired properties in the prepolymer blend or the crosslinked polyimide matrix.
