Abstract

The invention relates to a ballistic resistant article, such as a helmet (1), comprising a double curved shell (2) in turn comprising a stack (5) of layers (6) of an oriented anti-ballistic material, the layers (6) comprising one or more plies and having a plurality of cuts (7), the ends of which define a central polygon (8) and lobes (10) extending from the polygon (8). The stack (5) comprises at least rotationally staggered layers (6) and, for most successive layers (6), 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 (6) over an angle of 90° ± 30°.
