Abstract

Provided is a solid rocket motor (SRM) insulation, wherein carbon nano fibers (CNF) are blended into a polyurethane matrix so as to disperse the CNF in the polymer. The so blended material is then extruded, injection molded or sprayed on or into the desired shape. Such SRM insulation has reduced ablation over prior art insulations, resulting in reduction in weight of the insulation needed in such rockets, permitting increase of payload therein.
