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.

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: A compound for protection of an object from a blast or shock wave. The compound include a matrix material and at least a first and second sets of inclusions in the matrix material that differ in size, quantity, shape and/or composition in a direction through the impact-absorbing material, the combination of which contributes to the ability of the material to exhibit at least one property that changes as the inclusions are deformed in response to a blast or shock wave.

Abstract: An igniter system and method for igniting a propellant by an optical energy source. The igniter system including an igniter composite and a propellant. The igniter composite including a reactive component and a fluoropolymer. The propellant is coupled to the igniter composite. The igniter composite has a composition including nano-aluminum at ideal stoichiometry in polyvinylidene fluoride. The igniter composite is configured to achieve a sustained ignition from a wavelength emitted from the optical energy source. The wavelength is between around 250 nanometers to around 1100 nanometers.
