Abstract
A composite ballistics protective textile structure comprises at least a textile element and one or more textile or thermoplastic matrix elements. The first textile element comprises unidirectional yarn fibers or flat strips. The second textile element comprises flat strip elements consisting of unidirectional yarns or thermoplastic films. Additional elements comprise thermoplastic matrix arrangements, based on rubber, elastomeric polymers or being laminated with thermoplastic films, for stabilizing the structure and reducing bullet trauma impacts.
Claims13
A ballistics protective bullet-resistant textile structure providing a quick dissipation of an energy of a penetrating bullet, comprising:
- a first warp textile element comprising unidirectional matrix yarns or flat strips;
- a second weft textile element consisting of unidirectional flat strips of a thermoplastic material;
- said unidirectional yarns or flat strips of said first warp textile element being interleaved in a warp arrangement with said second weft textile element;
- said thermoplastic material of second weft textile element being partially softened or melted to rigidly bind said unidirectional matrix yarns or flat strips of said first warp textile element;
- and
- a third non-textile stabilizing element impregnated in said first warp textile element and said second weft textile element for stabilizing and reducing bullet impact traumas, said third non-textile stabilizing element comprising rubber or elastomeric polymer materials or a combination thereof laminated with thermoplastic films;
- said first warp textile element comprising para-aramid matrix yarns or flat strips, or yarns or flat strips of an ultra-high-molecular-weight polyethylene (UHMWPE) matrix;
- said second weft textile element consisting of flat strips of a para-aramid matrix, processed by glue, adhesive or thermoplastics matrix materials, or UHMWPE matrix flat strips, or thermoplastics films such as polyethylene (PE), polyurethane (PU), polypropylene (PP), polyamide (PA), ethylene-vinyl acetate (EVA), or any thermoplastics materials adapted to be extruded to a film form;
- and
- said weft flat strips having a height less than or equal to 2 cm.
