Abstract
A polyimide composition and polyimide composite are provided. The composition has a polyimide resin, a reactive plasticizer and a phosphate. The composition is crosslinked and exhibits desired levels of processability and improved thermooxidative stability. The composites have a polyimide resin, a phosphate and reinforcing fibers, and exhibit reduced wear and friction. The compositions and composites are useful for making aircraft engine hardware such as bushings.
