Abstract
Described is a ballistic resistant article, such as a helmet, having a double curved shell in turn has a stack of layers of an oriented anti-ballistic material, the layers having one or more plies and having a plurality of cuts, the ends of which define a central polygon and lobes extending from the polygon. The stack has at least 10 rotationally staggered layers and, for most successive layers, the orientation of the material in the or at least one of the plies is rotationally staggered relative to the orientation of the material in the or at least one of the plies of a successive layer over an angle of 90°±30°.
