    摘要: 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.

    摘要: Tailorable polyimide resin systems suitable for processing by resin transfer molding (RTM) and resin infusion (RI) methods. An exemplary resin system includes first and second prepolymer components present in respective amounts to provide the desired processibility. The cured polyimide system exhibits high glass transition temperature and other properties required for gas turbine engine applications. The first and second prepolymer components independently comprise a monomeric mixture or a reaction product of a diamine component, a dianhydride component, and an end group component.

    摘要: Method includes forming a preform utilizing a polyimide resin-impregnated fiber-reinforced layers; removing solvent from the system at initial vacuum, pressure, and temperature conditions for an initial time interval sufficient to remove substantially all the solvent; imidizing the polyimide resin system under second vacuum, pressure, and temperature conditions for a second time interval sufficient to substantially completely imidize the polyimide resin; consolidating the preform following imidization under third vacuum, pressure, and temperature conditions and including applying pressure to the preform when the preform is at a predetermined temperature; and solidifying the preform under fourth vacuum, pressure, and temperature conditions to provide a cured laminate structure having a shape of a turbine engine component. A method is provided for designing the polyimide resin overall cure cycle dependent on the desired outcome at the solvent removal stage, the imidization stage, the consolidation stage, and the solidification stage.
