Abstract: A composite penetrator has a plurality of dispersed high aspect ratio bodies of refractory heavy metal such as tungsten wires. A matrix of metal surrounds and wets the dispersed bodies for forming an integral penetrator. The matrix metal is characterized by having localized shear band deformation when strained.
