Reactive Shaped-Charge Liners for Penetrating Concrete Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-028 Topic Title: Reactive Shaped-Charge Liners for Penetrating Concrete Proposal No.: N081-028-1097 Firm: DE Technologies Inc. 3620 Horizon Drive King of Prussia, Pennsylvania 19406 Contact: William Flis Phone: (610) 270-9700 Web Site: www.detk.com Abstract: We propose to develop reactive composite materials for use as shaped-charge liners, with greater effectiveness in penetrating concrete and rock targets than conventional liner materials. The composites will consist of two materials that react with each other, in either oxidation-reduction (such as in a thermite) or intermetallic reactions. The component materials will initially be in the form of powders and will be assembled by conventional powder-metallurgy techniques. It is anticipated that the high-velocity jet projected by such a charge will not only effectively penetrate a concrete or rock target but react with it, greatly increasing the crater volume and the damage to the target. Such a charge will serve as a superior precursor charge for a follow-through warhead. Various material systems, morphologies, and fabrication techniques will be investigated. Benefits: The developed materials will enhance the effectiveness and reduce the size and weight of penetrators and other munitions. Commercial applications include shaped charges for oil well completion and mining. Return
