Abstract
The invention is directed to a radiation curable energetic composition, to a method of forming a three-dimensional energetic object, to a three-dimensional energetic object, and to uses of the radiation curable energetic composition. The radiation curable energetic composition of the invention comprises (a) one or more polymerisable components, (b) one or more polymerisation initiators, and (c) one or more energetic components.
Claims27
A method of forming a three-dimensional propellant charge having linear burn rate gradients in multiple directions, the method comprising:
- (a) forming a layer of a radiation curable energetic composition comprising:
- (i) one or more polymerisable components,
- (ii) one or more polymerisation photoinitiators, and
- (iii) one or more energetic components,
- (b) selectively curing said layer with actinic radiation, and
- (c) repeating the steps (a) and (b) a plurality of times to form said three-dimensional propellent charge, wherein said three-dimensional propellent charge has a linear burn rate gradients in multiple directions.
