High Density, High Strength, Highly Energetic Structural Materials for Enhanced Lethality Army Munition

Physical Sciences Inc., in collaboration with ATK Space Systems, proposes to develop unique reactive structural material (RSM) concepts and processing techniques that will simultaneously realize high mass density (> 7 g/cm3), high energy density (> 2 kcal/g or 8.36 kJ/g), and superior mechanical properties (tensile/compressive strength > 50 ksi). Our technique allows the RSM composition and process parameters to be tailored for specific applications by proper choice of constituent materials. In Phase I, we will demonstrate the feasibility of formulating and processing the RSM, and measure their mechanical, energetic, sensitivity, and thermal stability properties. We will produce RSM flat panels in the Phase I baseline program and cylindrical tubes in the Phase I Option program. In Phase II, we will optimize and refine the RSM formulations and process parameters, produce prototype munition components, and conduct energy release and lethality testing. Upon successful technology demonstration, we will work with the Army and ATK to transition the technology into operational munition systems.
