  • Patent number: 9982981
    Abstract: A munition, such as a projectile formed of at least one reactive material. In one embodiment, the projectile includes a body portion formed of at least one reactive material composition wherein the at least one reactive material composition defines at least a portion of an exterior surface of the projectile. In other words, a portion of the reactive material may be left “unbuffered” or exposed to the barrel of a gun or weapon from which it is launched and similarly exposed to a target with which the projectile subsequently impacts. In one embodiment, the projectile may be formed with a jacket surrounding a portion of the reactive material to provide additional structural integrity. The projectile may be formed by casting or pressing the reactive material into a desired shape, or the reactive material may be extruded into a near-net shape and then machined into the desired shape.

  • Publication number: 20150203415
    Abstract: A reactive material that includes at least one of a fuel, an oxidizer, and a class 1.1 explosive and is formulated for use in a reactive material projectile. The reactive material is formulated to provide at least one of an overpressure of greater than approximately 9 pounds per square inch at a radial measurement of 12 inches from a point of impact on a target, a hole greater than approximately 2 square inches at an optimum penetration level in a target, and pressure, damage, and a flame when the reactive material bullet impacts a target. The fuel may be a metal, a fusible metal alloy, an organic fuel, or mixtures thereof. The oxidizer may be an inorganic oxidizer, sulfur, a fluoropolymer, or mixtures thereof. A reactive material projectile having the reactive material disposed therein is also disclosed.

  • Patent number: RE45899
    Abstract: A reactive material for use as a reactive liner in penetrating (shape-charge) warheads and for use in reactive fragments in fragmenting warheads is disclosed. The reactive material comprises an oxidizing agent and a metal filler or metal/metal oxide filler. The oxidizing agent comprises a fluoropolymer having high fluorine content, a low melt temperature, and a high mechanical strength. Preferably, the fluoropolymer is a thermoplastic fluoropolymer, such as a polymer of tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride. The metal filler comprises a high density, reactive metal. Preferably, the metal filler is hafnium or tantalum.
