A high strength engineered reactive matrix composite that includes a core material and a reactive binder matrix combined in high volumes and with controlled spacing and distribution to produce both high strength and controlled reactivity. The engineered reactive matrix composite includes a repeating metal, ceramic, or composite particle core material and a reactive binder/matrix, and wherein the reactive/matrix binder is distributed relatively homogeneously around the core particles, and wherein the reactivity of the reactive binder/matrix is engineered by controlling the relative chemistry and interfacial surface area of the reactive components. These reactive materials are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties.

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.

The conformable pyrolant includes a fluorocarbon liquid, a fluorocarbon powder, and a micron size powdered aluminum bound together with a binder system that includes polyisobutylene and colloidal silicon dioxide. The conformable pyrolant is capable of achieving temperatures on the order 10,000 F., which will breach an ordnance item and thermally decompose an insensitive explosive fill. The conformable pyrolant also includes tungsten, wherein tungsten and silicon dioxide oxidize into fluorinated compounds, therein extending the burn and gasifying, therein enhancing ebullition and volume in general. The versatile conformable format is capable of being shaped into geometries for inclusion in ordnance items or molded into configurations for disposal of insensitive munitions.
