Abstract
A thermobaric explosive composition is provided that includes coated fuel particle, a nitramine, and binder. The coated fuel particles preferably have a magnesium core and an aluminum coating. Upon detonation, the nitramine disperses the coated fuel particles over a blast area during a first overpressure stage. The aluminum coating of the fuel particles has a thickness selected to provide an amount of aluminum that is stoichiometrically less than an amount of ambient-air oxygen available in the blast area for aerobic combustion with the aluminum during the first overpressure stage. Once exposed, the magnesium cores may combust to increase the impulse generated in the first overpressure stage. Also provided are articles of manufacture and related methods.
