DEVELOPMENT OF FLEXIBLE POLYMERS AS THERMAL INSULATION IN SOLID-PROPELLANT ROCKET MOTORS

Abstract

Flexible epoxy, phenolic, and melamine resins have been prepared. Tensile strength and per cent elongation have been determined on some of these asbestos-filled and unfilled materials. Many of the epoxy formulations have been evaluated as insulators by the oxyacetylene torchAND BY ACTUAL MOTOR FIRING, WHILE SEVERAL OF THE PHENOLIC MODIFICATIONS HAVE BEEN EVALUATED IN THE ARC-IMAGE FURNACE AND ARE CURRENTLY UNDERGOING OXYACETYLENE TORCH AND MOTOR FIRING TESTING. Three epoxies with the best performances are Epon 828-Nadic methyl anhydride modified with 30% OF CASTOR OIL, Epon 828 modified with EM-206, and Epon 815 modified with XR 2000. Test results from the arc-image furnace indicate that some phenolic-Syl Kem formulations are very promising. (Author)
