A method for making a pyrotechnic composition in accordance with an embodiment of the present technology includes flowing metal powder, polytetrafluoroethylene powder, and binder powder in separate respective feed streams toward an extruder. The binder powder includes adhesive material and polytetrafluoroethylene anticaking material coating the adhesive material. The method further includes interspersing the metal powder, the binder powder, and the fluoropolymer powder to form a mixture. This mixture is then subjected to an extrusion process during which the anticaking material coating the adhesive material is disrupted. This releases the adhesive material to bind together the metal powder and the polytetrafluoroethylene powder in the extrudate. The powder mixture includes no solvent at any time between being formed and being extruded, yet the extrudate is well-mixed and cohesive.

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.
