Abstract
A PBAN-based solid rocket motor propellant which includes more than 85% or more solids is provided. Propellants of this nature are possible using the combination of diepoxide curing agents and PBAN as a binder. The curing agents include diepoxides having 4 to about 10 carbon atoms. It has been observed that when a diepoxide curing agent is substituted for conventional curing agents, viscosities are significantly reduced, thus enabling the addition of higher percentages of solids in the propellant formulation. Total solids loading of over 85% are achievable while maintaining end-of-mix viscosities within acceptable ranges.
