Definitions

  • the present invention relates to a protective screen, and in particular a ballistic screen, intended in particular, but not exclusively, to allow the shielding of bodies, envelopes, protective screens, and in particular the shielding of so-called thin sheets such as those which are used in the civil industry for the lining of doors or the realization of automobile bodies.
  • sintered industrial ceramics which can be based on alumina or silica which breaks the core, so that the latter, immediately after penetration, is no longer pointed, but chipped, or even disintegrated into several pieces. It is then possible to stop such a core by a layer of composite shielding like Antigun (Trademark) or any other light shielding.
  • the problem which arises and which is resolved by the present invention is that of the cohesion of composite panels comprising ceramic and either stainless steel, or aluminum, or a panel of the Antigun type.
  • Adhesives are known which allow different layers to be brought together with suitable adhesion.
  • a violent shock such as a shot
  • the shock wave produced reaches a speed of the order of 9000 m / sec, when the speed of the projectile is 800 m / sec.
  • There is a correlative variation in volume which, independently of any mechanical effect, causes the adhesive layer to burst when it is hard, which leads to delamination of the layers and, possibly, the fall of the outer layer when it this consists of ceramic tiles.
  • the ceramic tiles adjacent to the tile having received the projectile fall or are cracked, which leads to the use of an external retaining or protective layer, the tiles being held after a projectile impact only by the retaining layer.
  • FR-A-2,565,162 describes a low temperature laminable polyurethane intended to bond two transparent layers such as glass and polycarbonate.
  • DE-A-2 344 277 relates to a bullet-proof vest comprising multilayer plates comprising a metallic layer and a layer of mineral material joined by an elastomeric layer of the rubber, polyurethane, PVC, etc. type.
  • this layer is only to distribute the energy and not to bond the layers, the elastomer layer and the metal layer of the bottom being linked, for example by bonding.
  • the structure of the materials used for the shielding makes them difficult to stick and very often does not hold on their support, in particular on aluminum, on stainless steel, or on composite materials, only by a suction cup effect.
  • the object of the present invention is to remedy this drawback and to allow the construction of panels resistant to very close intensive fire.
  • the multilayer protection panel is characterized in that the different layers are bonded using an aliphatic polyurethane whose Shore A hardness is 75, and whose softening point is 125 °.
  • the adhesive layer or layers should be relatively flexible to avoid any detachment after impact.
  • the polyurethane is chosen from the class of polyethers.
  • the present invention also relates to a method of manufacturing panels, characterized in that it consists in heating, inside an oven, the different layers of the panel, for a period of the order of 45 minutes, at a temperature between 150 and 200 ° until the edges of the polyether take on an amber color, then pass the assembly under press with a pressure of 2 to 10 bars, and allow the assembly to cool with outdoors.
  • the temperature increase is carried out gradually.
  • the existence of air bubbles in the polyether layer does not preclude obtaining a good bonding, so that it is not necessary to work under vacuum.
  • the adhesive used is included against the layers to be joined, in the form of a plastic film of between 0.38 m / m and 1.2 m / m which, during the heating operation, will melt and spread over the entire surface and possibly in the interstices formed in particular by ceramic tiles. Pressing ensures the final cohesion of the different layers.
  • This panel is formed from bottom to top by a layer 1 of aluminum, joined by a layer 2 of adhesive on a panel 3 of composite material known under the registered trademark "ANTIGUN", as described in patent FR-A-2 459 956, and composed of a light core surrounded by fibrous layers, for example based on aramides embedded in a polyester resin.
  • the Antigun panel supports, via a layer of glue 4 of polyether resin, ceramic tiles 5. As indicated in the figure, the tiles 5 can be surmounted by a light layer 6 of camouflage. Contrary to what happened in the prior art, this layer is not necessary mechanically for resistance to projectiles, but simply has the purpose of concealing the structure of the material.
