Abstract:
1. A flexible spike and ballistics panel having a strike surface and a rear surface, wherein the panel comprises: a strike face grouping comprising at least two strike face layers, each strike face layer comprising resin and high tenacity yarns, wherein the high tenacity yarns are in an amount of at least 50% by weight in each layer, wherein the high tenacity yarns have a tenacity of at least 5 grams per denier, and wherein the strike face grouping forms the strike surface of the panel; and, a rear face grouping comprising at least ten spike resistant textile layer, each textile layer comprising a plurality of interwoven yarns or fibers having a tenacity of about 5 or more grams per denier, wherein at least one of the surfaces of the spike resistant textile layer comprises about 10 wt. % or less, based on the total weight of the textile layer, of a coating comprising a plurality of particles having a diameter of about 20 μm or less, wherein the normalized stiffness of each strike face layer is about 3 to 50 times greater than the normalized stiffness of each textile layer.
