Abstract:
1. A mosaic armor system for protection against a stabbing threat having a threat thickness at a failing penetration depth, the armor system comprising: a top layer of solid elements and a middle layer of solid elements, the solid elements in both layers being arranged in substantially space-filling X-Y arrays in which the solid elements are separated from each other by gaps that intersect at apexes, the gaps having a uniform gap width that is between 5% and 20% of the threat thickness at the failing penetration depth, the middle layer being offset from the top layer in the Z direction by an offset that is at least three times larger than the gap width, a front face of the middle layer being adhered to a back face of the top layer; and fibrous top and bottom covering layers arranged so as to sandwich the two layers of solid elements there between.
