Abstract
A flexible armor system includes a rigid panel of a stiffness calculated to resist penetration by a known ballistic object, made from multiple layers of Ultra High Molecular Weight Poly-Ethylene fibers or other high tenacity fibers, which is then pre-flexed beyond its elastic bending limit to create a distributed pattern of surface buckling, with localized areas of interior delamination, which together function as bending or hinge lines to provide flexibility to the otherwise rigid panel and thereby lower its overall stiffness to less than that calculated for the rigid panel to resist the ballistic object. The areas of delamination have a width of less than one half the diameter of the ballistic object.
