Abstract

A radiation curable energetic composition that can be used, for example, to form pyrotechnic energetic components. The energetic composition includes a radiation curable polymer precursor and a pyrotechnic. The energetic composition may be dispersed in a liquid vehicle to facilitate deposition of the energetic composition using direct-write techniques.

Claims (43)

1 . A fluid formulation for the deposition of an energetic composition, the fluid formulation comprising:

a liquid vehicle; and

an energetic composition, the energetic composition comprising;

a radiation curable polymer precursor in an amount of at least about 0.05 wt. % and not greater than about 10 wt. % of the energetic composition, and

a pyrotechnic in an amount of at least about 75 wt. % and not greater than about 99 wt. % of the energetic composition.

2 . The fluid formulation recited in claim 1 , wherein the pyrotechnic is substantially insoluble in the liquid vehicle.

3 . The fluid formulation recited in claim 1 , wherein the liquid vehicle comprises an alcohol.

4 . The fluid formulation recited in claim 1 , wherein the liquid vehicle comprises a compound selected from isopropanol, ethanol, butanol, methanol, and mixtures thereof.

5 . The fluid composition recited in claim 1 , wherein the radiation curable polymer is an ultraviolet curable polymer precursor.

6 . The fluid formulation recited in claim 1 , wherein the energetic composition comprises at least about 0.1 wt. % of the radiation curable polymer precursor.

7 . (canceled)

8 . (canceled)

9 . The fluid formulation recited in claim 1 , wherein the energetic composition comprises not greater than about 7.5 wt. % of the radiation curable polymer precursor.

10 . (canceled)

11 . (canceled)

12 . The fluid formulation recited in claim 1 , wherein the radiation curable polymer precursor comprises an acrylate monomer.

13 . The fluid formulation recited in claim 1 , wherein the radiation curable polymer precursor comprises a monomer selected from the group consisting of tetraethylene glycol diacrylate, tripropylene glycol diacrylate, pentaerythritol triacrylate, and hexanediol diacrylate.

14 . (canceled)

15 . The fluid formulation recited in claim 1 , wherein the pyrotechnic comprises pyrotechnic particulate constituents.

16 - 21 . (canceled)

22 . The fluid formulation recited in claim 1 , wherein the pyrotechnic comprises a fuel and an oxidizer.

23 . The fluid formulation recited in claim 22 , wherein the fuel comprises boron.

24 . The fluid formulation recited in claim 22 , wherein the oxidizer comprises potassium nitrate.

25 . The fluid formulation recited in claim 22 , wherein the pyrotechnic comprises thermite.

26 - 28 . (canceled)

29 . The fluid formulation recited in claim 1 , wherein the pyrotechnic comprises an intermetallic pyrotechnic.

30 . (canceled)

31 . (canceled)

32 . The fluid formulation recited in claim 1 , wherein the fluid formulation further comprises a binder.

33 . (canceled)

34 . (canceled)

35 . The fluid composition recited in claim 1 , wherein the fluid composition comprises at least about 1 gram of the energetic composition per gram of the liquid vehicle.

36 . (canceled)

37 . The fluid composition recited in claim 1 , wherein the fluid composition has a viscosity of not greater than about 70,000 centipoise.

38 . A method for the deposition of an energetic material component, comprising the steps of:

first direct-write printing the fluid composition recited in claim 1 onto a substrate to form a first energetic material precursor layer;

first exposing the first energetic material precursor layer to a sufficient quantity of radiation to polymerize the radiation curable polymer precursor and form a first intermediate component precursor layer;

first removing the liquid vehicle from the first intermediate component precursor layer to form at least a first portion of the energetic material component.

39 - 42 . (canceled)

43 . An energetic material component comprising an energetic composition, the energetic composition comprising:

at least about 90 wt. % of a pyrotechnic; and

at least about 0.1 wt. % and not greater than about 5 wt. % of a cured UV polymer.

44 - 51 . (canceled)
