Abstract
A structure for ballistic protections is described. The structure includes at least two distinct textile elements which co-operate to stop an incident bullet along a direction, taking advantage of the dissipation of the energy associated to the bullet impact. The first textile element includes fibers capable of dissipating a part of the energy connected to the incident bullet impact owing to a crystalline phase change. The second textile element includes fibers capable of dissipating a part of energy associated to the incident bullet impact by fibrillation.

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.
