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.
