  • Low temperature, extrudable, high density reactive materials
    Patent number: 6962634
    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. The reactive material is safely processed at temperatures significantly below the thermal autoignition point of the reactive material.
