ABSTRACT:
A multi-layer ballistic or armor panel system includes a hard component strike layer that is a continuous planar assembly of tile elements, the planar assembly having a strike surface and a rear surface. Seams between the tile elements are substantially non-perpendicular to the strike surface, thereby tending to deflect incoming projectiles. Grooves may be formed in one or more of the strike surface and the rear surface of the tile elements to provide a preferential weakness. The armor panel system may also include a reinforcing layer on at least one of the strike surface and the rear surface. A backing layer may be provided after the rear surface.
