  • This type of stack offers great resistance to bullets and other impacts, but is heavy and rigid to wear, and we would like to have available a stack of this kind to use including a bulletproof vest that has the same benefits in term protection against bullets and / or knives, but is more comfortable to wear, especially less heavy and more flexible.
  • an article resistant to bullets and / or knives in particular a garment, for example a bulletproof vest, comprising a stack of fiber-based panels, comprising at least one first panel and at least one second panel, the or each second panel comprising a fabric, in particular a woven, in particular of aramid fibers, and a respective sheet of thermoplastic material fixed on one side of the fabric, is characterized in that the first panel or each first panel is constituted a plurality of sheets, each comprising a woven, in particular aramid, fixed to each other, in particular by being sewn together by one or more sewing threads along their peripheral edge.
  • each sheet is reinforced by a series of associated reinforcing threads, each thread of the series of threads associated with a sheet alternately passing from one side of the woven fabric to the other, without passing through another of the sheets of the of each first panel.
  • the son are parallel to each other, in particular by being spaced apart from each other in a regular manner, in particular by extending vertically, as defined when the vest is worn.
  • the or each first panel comprises at least 3 sheets, in particular between 5 and 9, still more preferably between 6 and 8 sheets, in particular 7 sheets.
  • each sheet of the first panel or first panel is laminated.
  • each woven sheet of the first panel or first panel has two folds or layers interwoven (-45 ° / + 45 °) of aramid fibers, preferably unidirectional.
  • each woven fabric of the or each first panel are consolidated together to form a sheet.
  • each sheet has a thickness of between 0.43 and 0.49 mm and a weight of between 490 and 530 g / m 2 .
  • a plurality of second panels in particular three second panels, separated from one another by one or more third panels, in particular two third panels between two successive second panels and two third panels. at the end of the stack on the side of the body.
  • each third panel consists of four folds of unidirectional aramid fibers crisscrossed at 0 ° / 90 ° / 0 ° / 90 ° bound.
  • a matrix is understood to mean a material which, in particular, binds the fibers, for example aramid or polyethylene fibers, of each of the aramid fiber plies, in particular aligned in one-way directions, and thus stabilizes the fibers inside them. of each or each of the folds of fibers and, after possible interleaving of the folds of fibers, binds them to one another.
  • cross or crisscross folds are understood to mean an arrangement of at least two monodirectional aligned fiber plies, wherein the at least two one-way aligned fiber plies are bonded to one another so that the fibers aligned of the two folds make an angle, preferably 90 °.
  • consolidated fold is understood to mean that the fibers of the fold or folds, in particular monodirectional aligned, are held together, in particular linked to each other by adding of a matrix material, by their overlap by two films, by a surface treatment, for example enzymage, or by a combination of two or more of these techniques.
  • fibers means an oblong body whose length dimension is much larger than a transverse dimension in width and thickness. Accordingly, fibers include fibers or monofilaments, multifilament fibers, ribbons, tapes, staple fibers, and yarns made from one or more of the foregoing examples, for example, multifilament yarns or yarns. short fiber base. Particularly preferably, fibers mean multifilament yarns.
  • the cross sections of the fibers to be used in the present invention can vary to a very large extent. They can be circular, flat, oblong in cross section. They may also be of regular or irregular shape, have a plurality of regular or irregular lobes protruding from the longitudinal axis, for example a filament. Preferably, the fibers have a substantially circular cross section.
  • aramid fibers are understood to mean fibers produced from an aromatic polyamide as the polymer forming the fiber.
  • aromatic polyamides P-aramid.
  • poly (p-phenyleneterephthalamide) is the most preferred.
  • Poly (p-phenyleneterephthalamide) results from polarization mole to mole of p-phenylenediamine and terephthalic acid dichloride.
  • Fibers, consisting for example of multifilament yarns made from poly (p-phenyleneterephthalamide), can be obtained under the trademark TWARON.
  • aramid fibers useful for forming the fabrics or plies of fibers in the panels of the bullet resistant articles of the present invention are those formed from the aromatic copolymer as the polymer forming the fiber.
  • a p-phenylene diamine and / or a terephthalic acid dichloride are partially or completely substituted by other aromatic diamines and / or dicarboxylic acid chlorides.
  • the bulletproof vest comprises a stack of panels, namely a first panel 1, (third) second panels 2 and third panels 3 which are arranged between each second panel and at the end of the panel. stacking on the side of the body or inside, while the first panel is on the side of the threat or outside. It is arranged two third panels 3 between two successive second panels 2.
  • the first panel 1 consists of seven (7) sheets 4 laminated and secured together by a peripheral seam. Instead of a seam 5, there could be adhesive fixation, thermal fusion, ultrasonic welding or the like.
  • Each sheet 4 consists of a woven formed of two folds or interlocking layers (-45 ° / + 45 °) of aramid fibers, preferably unidirectional.
  • each sheet can be provided a resin matrix ensuring the consolidation of the sheet, the woven fabric and the resin being sandwiched between two thermoplastic films, films which are adhered to the two surfaces of each layer, such as polyolefin films, linear low density polyethylene (LLDPE) films and ultra high molecular weight polyethylene (UHMWPE) films, as well as polyester films, nylon films, polycarbonate films and the like.
  • films can have any desired thickness, typically between 2 and 20 microns.
