Fragment Warhead with Reactive Composite Materials

We propose to develop and demonstrate a fragmentation warhead incorporating high-strength, high-density reactive composite materials as the warhead fragments. The materials will be com-posed of an active metal in the form of wire, wire-mesh, or powder, within a bonding matrix of an oxidizer-rich polymer. High strength and stiffness will be achieved by reinforcement with wire, fibers, and nanofibers. Material strength and density enable the fragment to survive explosive launch and increase its penetrating power. The reactivity of the material delivers significant thermal energy release in impacts and explosions. This energy provides increased lethality, especially in neutralizing explosive-containing munitions, such as rockets, artillery, and mortars. BENEFITS: The developed materials will enhance the lethality and reduce the size and weight of fragment and penetrating warheads for attacking various targets.
