Abstract: A high temperature polymer composite includes nanocomposite material, such as carbon nanotubes, dispersed in polymer matrix composite resin interlayer region, which may include bismaleimide or polyamide resin, between fiber containing plies. The nanocomposite material may be in an operating temperature in a range between 400-800 degrees Fahrenheit. Gas turbine engine parts or components such as airfoils, stator vanes, casings, and ducts may be made of the high temperature polymer composite.

Abstract: A tooling assembly and method for forming a flange of a composite component is provided. The tooling assembly includes a mold configured to receive a composite material. The composite material may include a plurality of fabric plies impregnated with resin. The fabric plies may be debulked as they are being laid using a plurality of debulking tools, with the radius of each debulking tool growing as additional fabric plies are laid. A gas-permeable bagging material may be placed along the edge of the composite material to restrict resin flow while allowing for outgassing. The tooling assembly may further include a flange shoe tool that is joined with the mold to form the flange of the composite material. The mold and flange shoe tool may define a chamber and venting passageways that allow gases such as volatile compounds to escape while the composite component is being cured.
