Composite propellant formulations containing a novel combination of bonding agent and cure catalyst together with carefully balanced HTPB binder and isocyanate curative may be mixed, cast, and cured at ambient temperature. The NCO/OH ratio is in the range from about 0.8 to about 0.9. The propellant formulations include as typical solid ingredients an oxidizer such as ammonium perchlorate and a reactive metal fuel such as aluminum. A plasticizer may optionally be included in the propellant to improve processing and low temperature properties. The bonding ...
A solid propellant formulation capable of being mixed, cast, and cured at ambient temperature comprising: hydroxy-terminated polybutadiene binder present in an amount ranging from about 8% to about 20% by weight; an isocyanate curative present in an amount ranging from about 0.7% to about 1.6% by weight, such that the NCO/OH ratio is in the range from about 0.8 to about 0.9; a cure catalyst; an oxidizer present in an amount ranging from about 50% to about 90% by weight; a fuel present in an amount ranging from about 0% to about 20% by weight; and a bond...
