ABSTRACT:
A flexible spike and ballistics panel having a strike surface and a rear surface. The panel contains a strike face grouping and a rear face grouping, where the normalized stiffness of each strike face layer is about 3 to 50 times greater than the normalized stiffness of each textile layer. The strike face grouping contains at least two strike face layers, each strike face layer having resin and high tenacity yarns, where the high tenacity yarns are in an amount of at least 50% by weight in each layer, where the high tenacity yarns have a tenacity of at least 5 grams per denier, and where the strike face grouping forms the strike surface of the panel. The rear face grouping contains at least ten layers of a spike resistant textile layer, each textile layer having a plurality of interwoven yarns or fibers having a tenacity of about 5 or more grams per denier, where at least one of the surfaces of the spike resistant textile layer contains 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.
