Abstract: The present invention relates to a structure for producing ballistic protection which combines high levels of performance in terms of stopping bullets and reducing trauma with great flexibility and breathability. A ballistic laminate comprising joined together unidirectional layers is produced. The ballistic laminate provided by the present invention is preferably produced by superposing at least two layers of ballistic yarns 101 and 103, arranged unidirectionally according to directions inclined relative to one another by approximately 90° (+/?10°). Each layer comprises a plurality of fibres arranged unidirectionally according to a substantially mutually parallel direction (+/?10°).

Abstract: The present invention relates to a structure for the construction of ballistic protection that combines high projectile-stopping and trauma-reduction performance with high flexibility. A ballistic laminate comprising at least two pairs of unidirectional layers, with fibers parallel to each other, separated by a connecting layer, is produced. In a preferred embodiment, the ballistic structure includes a plurality of unidirectional ballistic yarn sublaminates Each sublaminate comprises at least two unidirectional ballistic layers whose fibers are substantially parallel, i.e. oriented in the same direction; the two ballistic layers with parallel fibers are not in direct contact with each other but are separated (and held together) by a layer consisting, for example, of a film which is also adhesive. The sublaminates are then coupled together so that the unidirectional fibers of each sublaminate are substantially perpendicular to those of the adjacent sublaminate.

Abstract: The ballistic structure for personal protection according to the present invention includes a plurality of rigid structures, separated from one another, in which at least one rigid element is formed by layering of leaves made of high molecular weight polyethylene tapes arranged in parallel and unidirectional fashion wherein these leaves are cross-plied and pressed at high temperature, with adhesive polymers being laid down on at least one face of the single leaves, and in which at least another rigid element is formed by a layering of unidirectional resin-impregnated yarns, wherein each layer of unidirectional yarn is crossed with the subsequent one. Such layering is pressed at high pressure and at high temperature. In a preferred embodiment, the rigid structure, which is the first to be impacted by the bullet, is made of a rigid element composed of ultra high molecular weight polyethylene yarn.

Abstract: A ballistic protection is described. The ballistic protection includes a rigid structure and a flexible structure, co-operating to dissipate energy associated to an incident bullet impact, the rigid structure and the flexible structure being separated by at least a first discontinuity layer. The rigid structure includes at least a first rigid layer, at least a second rigid layer, and at least a third layer interposed between the first and the second rigid layer. The material of the first discontinuity layer and of the third layer of the rigid structure are selected so that a speed of propagation of a sound wave through the first discontinuity layer and the third layer of the rigid structure is less than 50% of the speed of propagation of a sound wave through fibers of the first rigid layer. The third layer can have a frame shape extending along the edges of the ballistic rigid protections, so that protection is increased along the borders.
