Abstract: A reactive burning rate accelerator is provided that is configured to be at least partially embedded in a solid energetic material and comprises at least one metallic component and at least one non-metallic component. The reactive burning rate accelerator is configured to ignite and combust to increase the mass burning rate of the solid energetic material. Also provided are solid energetic materials comprising the reactive burning accelerator and methods of manufacturing and using the same.

Abstract: Three-dimensional (3D) printed fluoropolymer-based energetic compositions are made using 3D printing methods. The 3D printed fluoropolymer-based energetic compositions comprise a fluoropolymer and a reactive metal or metal oxide. The total weight percentage of the fluoropolymer and the reactive metal or metal oxide is 70-100% of the 3D printed fluoropolymer-based energetic composition, and the weight percentage of the reactive metal or metal oxide is 5-85 wt % of the total weight of the 3D printed fluoropolymer-based energetic material. The 3D printed fluoropolymer-based energetic material has a thickness of at least 200 μm.
