ABSTRACT:
Mechanical properties of composite modified double-base propellant are improved by coating fillers for the propellant with a crosslinked, binder insoluble coating having reactive surface isocyanate groups. The reactive isocyanate groups become chemically bound to the nitrocellulose binder of the propellant during propellant cure. Failure of the propellant at the binder-filler interface under conditions of stress is substantially reduced.
