Toughened High-Temperature Thermoset Composites
Abstract
Laminated composites of carbon fibers and either PMR-15 or LARC(TM)RP-46 polyimides toughened selectively by incorporating thin layers of Matrimid(TM) 5218 thermoplastic polyimide at interfaces between plies to form gradient semi-interpenetrating microstuctures. Toughening of composites accompanied by acceptably small decreases in strength and stiffness. Thick laminates of toughened composites fabricated easily at 500 psi. Materials useful in components of aircraft engines, where exposed to high temperatures for short times.
