High-Energy-Density LCA-Coupled Structural Energetic Materials for Counter WMD Applications

Abstract

The major goals of this research project are to investigate the coupling of Linear Cellular Alloys (LCAs) as casings for reactive (thermite) fillers as high-energy-density structural energetic materials. The specific objectives include performing fundamental studies to: (a) investigate mechanics of dynamic densification and reaction initiation in Ta+Fe2O3 and Ta+Bi2O3 thermite powder mixtures and to (b) design and fabricate LCAs of intent (maraging steel) and reactive (tantalum) metals with cell geometries that provide stress transfer for chemical reaction initiation in the thermite filler and allow controlled fragmentation.
