Abstract
An armor includes a face sheet, a spall liner, and a core disposed between the face sheet and the spall liner. The core includes a polymeric matrix and a plurality of ceramic rods disposed in the polymeric matrix. The armor further includes a first shock dissipation layer disposed between the face sheet and the core. The armor optionally includes a second shock dissipation layer disposed between the spall liner and the core.
