ABSTRACT:
A solid rocket fuel formed by mixing a liquid hydroxyl terminated prepolymer such as polybutadiene, with hexamethylenetetramine, and adding a cross-linking agent, particularly a multifunctional isocyanate. The mixture is poured or cast into a mold, cartrige, or insulated motor case and cured, preferably at ambient temperature. The hexamethylenetetramine is employed as the major fuel component in an amount in the range of about 60 to about 83% based on the total weight of the fuel. The preferred curing or cross-linking agent is a liquid multifunctional isocyanate. Processing aids and/or mechanical property modifiers can be added in minor amounts.
