Research Topics


Metafex (for metal-fueled explosive replacement) combines the technologies of explosive reaction thermochemistry and pulsed electrical power. The technology will make systems formerly requiring hazardous explosives not only safer and more energetic but also less environmentally disruptive and lower in cost. Analysis shows that Metafex energy densities are more than twice as great as those of conventional explosives. Because the energy density is greater, weapon components can be made smaller and/or more effective, yet safer, if they use Metafex in place of explosives. There are many US Navy applications, including linear shaped charges (LSC's) for salvage and obstacle clearance operations. By replacing the high explosive with Metafex, LSC's will be safer. Because they will be safer, they will be less costly to manufacture, to ship, and to use. Also, disposal of obsolete ordnance will be non-hazardous. In contrast to conventional ones, the proposed LSC's require no explosives. They are environmentally benign, can be safely shipped anywhere; and need no special handling. They will be inert until activated by energetic electrical pulses. In Phase I of the proposed project, Metafex test samples will be built and tested, and the technology will be adapted for use in LSC's.
