A ballistic-resistant molded article includes a compressed stack of sheets made up of reinforcing tapes having a tensile strength of at least 1.0 GPa, a tensile modulus of at least 40 GPa, and a tensile energy-to-break of at least 15 J/g, the direction of the tapes within the compressed stack being not unidirectional. The stack includes a first layer of sheets including reinforcing tapes and a high-density polyethylene (HDPE) as matrix material and a further layer of sheets including reinforcing tapes and a thermoplastic elastomer as matrix material, wherein the further layer includes 0.2-8 wt. % matrix material.

Ballistic resistant articles comprising tapes

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&#xb0;&#xb1;30&#xb0;.
