Definitions

  • the present invention relates to glazing resistant to bullets and / or chips and / or other projectiles of the same type.
  • the ballistic resistance is understood here for levels as high as BR 3, BR 4, BR 5, BR 6 and BR 7 of the FR EN 1063 standard.
  • the ballistic resistance depends on the glass composition (number and thickness of the glass sheets). This is defined on a case-by-case basis, depending on the level of protection required.
  • the bullet during impact impacts (angle of fire compared to the normal bullet-proof glass), the bullet always progresses in the glass by increasing the angle of incidence by ricochet effect.
  • the ricochet effect combines with the effect of the points of ballistic attraction, defining the trajectory of the bullet in the thickness of the glazing.
  • the bullet-proof glazing comprises, on the rear face, a sheet of non-fragile organic material with elasto-plastic behavior under high-speed ballistic impacts, such as polycarbonate.
  • This rear face provides optimal ballistic efficiency when it can deform isotropically and form a "dome” or "bulb".
  • the proximity of the edges of this sheet is an element that can reduce the ballistic performance of the glazing.
  • the present invention aims to significantly improve the ballistic resistance glazing.
  • This resistance is sought on the inside face of the glazing, which may consist of a polycarbonate sheet, on the offset of a part of the periphery - constituted for example by the free surface of a metal rapplique -, as well as on the edge of the ballistic block - consisting for example of a ribbon now adhering to polycarbonate and metal plates
  • the shape of the glazing in particular in its peripheral part, must be adapted to the assembly for which it is intended.
  • the thickness of the shifted can be conveniently adapted to be introduced into the rabbet of a body.
  • the invention which relates to a laminated transparent anti-bullet and / or splinter structure comprising three stacks of glass sheets all interconnected by interlayers adhesive layers, characterized in that in a part at less than the periphery of the laminated structure, the first stack is adjacent and protruding from the second stack, itself adjacent and protruding from the third stack, in that a rapplique anti-bullet material and / or anti-glare is adhered to the laminated structure on the free peripheral surface of the first stack, the edge and the free peripheral surface of the second stack and the edge of the third stack, and in that a transparent sheet of plastics material suitable for absorbing energy is stuck on the rapplique and the free face of the third stack.
  • glass essentially refers to a mineral glass such as float silicosodocalcium, but also to a rigid transparent plastics material of the acrylic type (poly (methyl methacrylate) ...), polycarbonate, ionomeric resin ... If said second stack is thicker than the rapplique, it can take a form in three parts, can be called "Z".
  • the rapplique can have a form in two parallel parts, obtained by suppression of the central branch of the Z.
  • the laminated structure is intended to be mounted so that the eventual impact occurs on the side of said first stack.
  • the region of greatest vulnerability consists of the adhesive joining the rapplique and chant said third stack.
  • this region of vulnerability is both of reduced dimensions, and the farthest possible from the impact zone, so that only less vulnerable core fragments of lower energy achieve this.
  • the invention consists in enclosing by metal rappliques - or equivalent - the edge zone offset of the glazing, to secure the ballistic attraction zone of greater fragility (more fragile material edge fold glass).
  • the invention retains an optimal efficiency of the deformed polycarbonate sheet by maintaining a protected edge area of the rapplique and not sprayed during impact, which will give a bearing surface reliable to allow the polycarbonate to deform into a bulb.
  • the ballistic steel connection must also maintain the rigidity of the glass assembly after the first impact and force the polycarbonate to work optimally and absorb the maximum energy.
  • the song of the rapplique is attached to the song of said third stack.
  • the passage in autoclave presents risks of breakage by cleavage of the fold of glass (scales) in contact with a metal rapplique by effect thermomechanical.
  • the present invention allows the use of a tackified adhesive bumper a polyurethane face of 0.38 mm. It is important for the ballistic behavior of the glazing that this bumper is the finest and most rigid possible.
  • the rapplique is secured to the free peripheral surface of said first stack in particular by the use of a double-sided adhesive foam during a passage in an autoclave, or by gluing in non-autoclave finish on the already laminated glazing. It is possible to use an acrylic adhesive, polyurethane ... provided that it provides a very good adhesion resistance during a bullet impact, the durability required under the conditions of use (automobile, %), an aptitude for compensate for differences in shape between parts thanks to its foam texture, for example.
  • the anti-bale and / or splintering material of the rapplique may be metallic (steel %), or composite plastic-reinforcing fibers (glass, aramid ).
  • the rapplique is: either integral, that is to say in one part, or in several parts secured by glue (polyurethane, acrylic ).
  • At least one glass sheet of said second stack is in protrusion with respect to at least one other sheet of glass of said second stack, and the rapplique is penetrating relative to the edges of said at least one glass sheet protruding from said second stack. It is also not excluded in this case that the rapplique is also penetrating with respect to said third stack.
  • Said at least part of the periphery of the laminated structure preferably comprises the upper edge and the two lateral edges.
  • three of the four sides of a quadrilateral are ballistic reinforced according to the invention.
  • the free faces of the laminated structure are flush (or flush). The advantages are related to ease of assembly, aerodynamics, and the possibility of sliding in the case of movable windows (sliding).
  • the adhesion of the rapplique and said plastic sheet is maintained by a tape that covers the free edges of the assembly.
  • This tape consists for example of the combination of thermoplastic polyurethane adhesive and an encapsulating polyurethane, not softening at assembly temperatures in an autoclave, but at a temperature of the order of 180 ° C.
  • Hardness The encapsulation PU is, for example, of the order of 85 ⁇ 5 Shore A.
  • the combination of the two PUs thus combines at the same time a rigidity in order to correct the misalignment of the constituents of the laminated structure and a flexibility for adapt to this misalignment.
  • the thermoplastic PU ensures the bonding of the encapsulating PU with the contact on the one hand, with the edge of the plastic sheet on the other hand.
  • the ribbon is on the other hand shear-resistant to which the subjacent constituents submit it, in particular in case of impact. It also performs an anti-flash function.
  • An equivalent ribbon may be glued to the edge of said first stack and the rapplique.
  • the invention furthermore relates to a method of manufacturing a laminated structure described above, characterized in that it comprises - the assembly of the glass block, then its autoclaving at 140.degree.
  • a building glazing or transport vehicle particularly an automobile such as windshield, fixed or mobile side glazing, or rear window, comprising a laminated structure described above; the application of such a laminated structure to stop three shots of perforating bullets of 7.62 x 51 P80 type, defined by - points of impact aligned and distant two by two 120 mm, in the area of said at least a portion of the periphery of the laminated structure, the point of the first impact being in the middle of the other two, - bale speeds 820 ⁇ 10 m / s, and by
  • PC varnished polycarbonate coated with a scratch-resistant varnish
  • the method of manufacturing this laminated structure is now described.
  • the glass block a, b, c, d, e, g, h, i, j, k is assembled and then introduced in an autoclave at 145 ° C.
  • the laminated structure obtained resists all shots made in the following manner: laminated structure: 500 x 200 mm test specimen; - three rounds of perforating bullets 7.62 x 51 P80; points of impact aligned and distant two by two 120 mm, in the peripheral zone according to the invention of the glazing; the point of the first impact being in the middle of the other two; speed 820 ⁇ 10 m / s; - shooting angles located in a cone of 20 ° compared to normal to the laminated structure.
  • a glazing unit differing from that of the invention in that the rapplique q is penetrating, and the absence of rappliques s and u, is crossed at the second impact in more than 50% of cases.
