Abstract
Explosives using thermally expandable microspheres (TEMs) in a solid matrix are disclosed that facilitate tunable changes in local density, porosity, and ultimately, shock sensitivity. Solid high explosive systems with 'on demand' shock sensitivity may be created. A relatively small fraction (e.g., 1% or less) of TEMs may incorporated during the manufacturing process of the solid matrix explosive (e.g., polymer-bonded explosives (PBX), trinitrotoluene (TNT), etc.). The fraction of TEMs used to achieve the desired explosive properties will depend on the base explosive material to achieve the desired initiation sensitivity.
