Definitions

  • the present invention relates to the production of a protective shield of the type that is incorporated into clothing to constitute a ballistic protective lining.
  • a protective shield of the type that is incorporated into clothing to constitute a ballistic protective lining.
  • Such shielding is in particular intended for the production of bullet-proof vests that the police wear during interventions which may expose them to ballistic fire.
  • the invention essentially aims to allow the manufacture of a body protection material offering sufficient protection against projectiles originating in particular from handguns and also having satisfactory comfort and freedom of use.
  • the ballistic armor produced according to the invention with this material can be inserted into compartments fitted for this purpose in different types of civilian, military, etc. clothing. It can thus be used in particular to constitute the bullet-proof plastron of a ballistic protection vest, which for the rest will be of any type known per se.
  • Polyamide fibers are used in the manufacture of protective vests. It is now industrially arylamide fibers, including more particularly the phenylphthalamides which are known in the trade under the name of Kevlar. These fibers have a high resistance to elongation and to tension. Protective structures are thus made up of one or more layers of a tightly textured fabric made of these fibers. However, it has been realized that the superposition of several layers of this fabric leads to the use of folds in which a projectile can be inserted. This in turn requires that these layers of arylamide fiber fabric be sewn together.
  • the probability of a projectile being stopped by a flexible protective material depends on the type of armor, the speed of the projectile, as well as various other parameters such as the type of ammunition, atmospheric conditions more or less dry or humid, etc.
  • body armor is generally designed to stop specific threats, falling within a specific speed range based on armor standards and the expected threat.
  • the subject of the invention is a ballistic armor for body protection, useful in particular against handgun projectiles, which is characterized in that it comprises, incorporated within it, at least one layer of a fracturable material under the effect of a deformation of its surface placed behind layers of conventional, flexible material, preferably of the polyolefin fiber type, which cover the surface of said material exposed to impacts.
  • the body shielding meets two requirements: to stop the projectile by dissipating energy translated into deformation effort, but also not to cause a deformation of the shielding itself too strong, in order to avoid any trauma linked to the shock.
  • a layer of material is used which is opposed to this deformation by fracturing immediately upon impact, thus creating an empty space in which the deformation of the deformable layers can advantageously be accommodated and thus avoid traumatic deformation of the rear of the ballistic armor.
  • Very high molecular weight polyolefin fibers are already used in body protection. They lead to materials which have a fairly high resistance to weight ratio and thus offer a high stopping power.
  • the polyolefin fibers most often made of polyethylene have a high wave propagation speed (12,300 m / s) which allows absorption and dispersion of the impact energy of a projectile over a maximum surface.
  • the ballistic protective shielding must include at least 45 sheets of polyethylene so that the deformation caused on impact is sufficiently reduced from one side to the other of the total thickness shielding. And if we want to increase the characteristics concerning the wearing comfort or the invisibility of the material inserted in civilian clothes, we run into the problem that by reducing the thickness of the shielding, we then increase the deformation of the internal face leading to the risk of shock-related trauma.
  • the ballistic armor according to the invention advantageously makes it possible to be satisfied with a thickness of material flexible type of sheets made of smaller polyethylene fibers, generally not exceeding about 30 to 35 sheets, thanks to the fact that there is incorporated a layer of a material whose walls are billable and thus allows for a lesser thickness in total, to offer the same protection against trauma that could be caused by the impact of a projectile.
  • polyolefin fibers Compared to polyamide fibers, polyolefin fibers, and more particularly those made of polyethylene, exhibit more efficient characteristics, such as toughness and elasticity, and this for a relative density lower than that of polyamide fibers such as Kevlar.
  • the toughness (PSI) is of the order of 375.10 3 to 435.10 3 while for polyamide fibers, it is of the order of 273.10 3 .
  • the elastic modulus (PSI) varies from 17.4.10 6 to 24.8.10 6 while it is 9.8.10 6 for polyamides.
  • polyethylene fibers are used either as a woven or as a non-woven material.
  • the latter is presented as a sheet consisting of a layer of polyethylene fibers placed in one direction and another layer of fibers placed in another direction.
  • the two layers of fibers are linked by resin in orientations of 0 ° and 90 ° in particular.
  • the layers of polyethylene fibers are most often covered with a film of a flexible thermoplastic resin.
  • Said sheets thus formed have the advantage of overcoming the pleating to which the woven fabrics are subjected and which reduces the system's capacity to remain under tension and to immediately absorb the energy of the projectile.
  • said sheets allow a uniform distribution of the stresses along the directions of the fibers unlike woven systems where the stresses are absorbed locally.
  • the fiber layer structure also allows many more fibers to come into contact with a projectile upon initial impact.
  • the resin which binds the fibers keeps them under the shock wave of the projectile which tries to push them out of its path.
  • the absorption and dispersion capacity of the impact energy of a projectile is given by the flexibility of the polyolefin fiber sheets, their elongation power and by the better distribution of the stresses obtained by the fiber layer structure. of said sheets.
  • the layer of fracturable material has a honeycomb structure, in particular of the honeycomb type, the walls of which are preferably made of organic material, so that the assembly has good mechanical strength while remaining fragile in dynamics.
  • This fragility to dynamic forces advantageously allows said material to fracture immediately and thus free up an empty space which allows the deformation of the deformable layers to become lodged and thus particularly advantageously opposes the pursuit of said deformation and thus avoids any risk of trauma which would no longer be linked to the projectile itself but to the deformation it causes when it penetrates and stops in the flexible homogeneous layers.
  • the layer of fracturable material can be formed by a honeycomb structure with non-metallic fracturable walls, which forms generally hexagonal cells opening on the surface of the layer, but as a variant, equivalent materials can be used, as can be for example a set of several thicknesses of a plastic film enclosing air bubbles, which under the pressure exerted by the deformation of said film thicknesses will burst and thus generate a vacuum.
  • such a non-metallic honeycomb layer is made from polyamide resin paper, in particular phenylphthalamide such as that commonly known in the trade under the name Nomex, which is impregnated with phenolic resin, according to aeronautical specification MIL-R-9299.
  • This material due to the bond produced between the arylamide fibers and the phenolic resin, has a high mechanical resistance to compression, shock, vibration and fatigue.
  • honeycombs with a hexagonal cell diameter of 3.2 or 4.0 mm are used for a density of the order of 24 to 29 kg / m 3 .
  • the preferred honeycombs have a thickness of the order of 3 to 4 mm.
  • Ballistic tests conducted using a protective armor according to the invention were carried out and showed that it was destroyed over about 1 cm in diameter, while for arylamide fibers for example, the destruction of the shielding occurs on a surface of 2 to 4 cm in diameter.
  • the deformation cone is advantageously reduced thanks to the invention.
  • the sheets of fiber layers will play in flexibility while the woven structures will oppose a certain resistance because of their greater rigidity, the material with fracturable walls always playing the same role.
  • a honeycomb layer and a plastic film with air bubbles can advantageously be used as fracturable material.
  • the vest of FIG. 1 has a plastron, within its lining, a ballistic protection armor 1 against handguns, which consists of several layers which appear in the exploded view of FIG. 2.
  • the extreme polyethylene layers 5 and 6 are joined together all around the faceplate, either by sewing, or preferably by heat sealing, in order to maintain the assembly.
  • the first layer of polyethylene on the outer surface, ie 5 is extended to flexibly wrap the assembly, including the fracturable layer which is relatively rigid, until it reaches the opposite extreme layer 6 which slightly overflows from the intermediate layers. which remain free inside the envelope thus formed.
  • the sheets of polyethylene fibers are sewn so as to avoid any spacing between the sheets in the thickness at the time of impact, spacing which would then generate a reduction in the efficiency of the system insofar as only the surface sheets would work.
