Abstract:
1. A structure for rigid ballistic protections, comprising a first textile element, a second textile element, co-operating to dissipate energy associated to an incident bullet impact, and a third element placed between said first textile element and said second textile element wherein: said first textile element includes first fibers capable of dissipating a part of said energy associated to the incident bullet impact by modifying the crystalline phase; said second textile element includes second fibers capable of dissipating a part of energy associated to the incident bullet impact by fibrillation; said first textile element and said second textile element are not directly or indirectly adhered to each other; said third element provides a discontinuity between the first textile element and said second textile element; and said first textile element, second textile element, and third element are each made of different materials, wherein the first fibers include UHMW polyethylene fibers, the second fibers are aramidic fibers and the third element is made of materials selected from the group consisting of: elastomeric based foams, plastomeric polymers, thermosetting silicones or mixtures thereof, felts, honeycomb structures, siliconized paper, and rubber, and wherein the structure comprises 60% to 85% by weight of the first element, 36% to 15% of the second element, and greater than 0% and up to 4% of the third element.
