Abstract

The invention makes it possible to obtain a new generation of thin and high-performance bullet-proof and explosion-proof glazing. The innovation in this four-component glazing, glass 1, elastomer 2, polycarbonate 3 and methacrylate 4, consists in the use of an elastomer having a high elastic modulus as a damper, distributor and brake of the shock waves. Of innovating use of a methyl methacrylate 4, as a surface finish, as it is superior to polycarbonates because of its optical qualities. The methacrylate makes it possible to avoid the use of anti-abrasion treated polycarbonates which are unsuitable for ballistic applications as they are embrittled by their surface treatment.

Description

Les performances des vitrages oare balles son- limitées par le poids et la perte de transparence dus à l'augmentation d'épaisseur.Il est nécéssaire d'élever les performances du vitrage tout en conservant un bon coefficient de transmission lumineuse. The performance of bullet glass is limited by the weight and the loss of transparency due to the increase in thickness. It is necessary to increase the performance of the glazing while maintaining a good coefficient of light transmission.

Le vitrage innovant associe les qualités des differents matériaux transparents(l),(2),(3),(4),et l'expérimentation confirme les gains de performances. The innovative glazing combines the qualities of different transparent materials (l), (2), (3), (4), and experimentation confirms the performance gains.

Le marché traditionnel des vitrages pare balles est constitué par deux familles:
I/ Glaces assemblées par des films de butyral de polyvinile,dont les inconvénients sont: a) le poids élevé,dangereux dés oue l'on dépasse le point de déchaussement en cas d'explosion.The traditional bulletproof glazing market is made up of two families:
I / Glass assembled by polyvinile butyral films, the drawbacks of which are: a) the high weight, dangerous as soon as one exceeds the heaving point in the event of an explosion.

b) la fragilisation de ces vitrages en dehors d'une piage de température de 10 à 450 centigrade.b) the embrittlement of these glazings outside a temperature range from 10 to 450 centigrade.

c) les projections vulnérantes en partie arriére
II/ Vitrages verre-polycarbonate,assemblés par differents moyens,mais les inconvénients communs sont: a) dégradations en extérieur,créees par les différences de dilatation entre le verre et le polycarbonate.c) the annoying projections in the rear part
II / Glass-polycarbonate glazing, assembled by different means, but the common drawbacks are: a) degradations outdoors, created by the differences in expansion between glass and polycarbonate.

b) les plaques de polycarbonate traitées anti abrasion sont fragilisées par le traitement de surface et sont détruites au premier impact.b) the anti-abrasion treated polycarbonate sheets are weakened by the surface treatment and are destroyed at the first impact.

c) les plaques oe polycarbonate non traitées anti abrasion sont sensibles au frottement et s'opacifient rapidement.c) the non-abrasion-resistant polycarbonate sheets are sensitive to friction and quickly become cloudy.

d) les plaqus de polycarbonate sont extrudées et présentent des déformations optiques importantes.d) the polycarbonate sheets are extruded and have significant optical deformations.

Les dessins annexés FIG. 1 et FIG. 2 présentent en coupe,face aux tireurs les constituants du vitrage innovant dans sa formulation minimum: 1) Un produit verrier feuilleté,symétrique ou non,chargé d'absorbe le flash de température crée par l'impact du projectile,d'éroder le projectile,. The accompanying drawings FIG. 1 and FIG. 2 present in section, facing the shooters, the constituents of innovative glazing in its minimum formulation: 1) A laminated glass product, symmetrical or not, responsible for absorbing the temperature flash created by the impact of the projectile, for eroding the projectile ,.

2) Un élastomére de + 5mm ,à grand module d'élasticité,répartissant les pre ssionsfreinant les ondes de choc,en gardant ses performances vis à vis des effets thermiques,compensant les differences de dilatation entre le verre et polycarbonate 3) Une plaque de polycarbonate non traitée anti abrasion,absorbant le choc et l'énergie de l'impact par sa souplesse et sa résistance mécanique.2) An elastomer of + 5mm, with a large modulus of elasticity, distributing the pres ssionsfringing the shock waves, keeping its performance with respect to thermal effects, compensating for the differences in expansion between the glass and polycarbonate 3) A plate of non-abrasion-resistant polycarbonate, absorbing shock and impact energy through its flexibility and mechanical resistance.

4) Une plaque de méthacrylate de méthyle de t lmm,ccilée sur le dernier polycarbonate avec le même type d'éiastomére (silicone bi-composant).4) A plate of methyl methacrylate of t lmm, eyelashed on the last polycarbonate with the same type of elastomer (two-component silicone).

Les méthacrylates de méthyle coulés a) offrent une qualité optique parfaite b) Protégent contre le frottement et éventuellement peuvent se rénover. Cast methyl methacrylates a) offer perfect optical quality b) Protect against friction and possibly can be renovated.

c).A l'impact,sa rupture en forme d'étoile,crée par la déformation du poly carbonate,limite les projections,et dans cetteéventualité un éclat de +lmm d'epaisseur et d'une densité de 1,2,ne présente pc de danger pour l'épiderme * Apurés expérimentation mesurée,le vitrage innovant aprés tir se présente comme suit.En face avant le verre feuilleté(1) est étoilé et creusé à l'em- placement de l'impact.En face arriére le polycarbonate (3) est bosselé. Sous cette poussée le méthacrylate de méthyle s'est étoilé sans perte de matiére sensible.c) .At impact, its star-shaped rupture, created by the deformation of the poly carbonate, limits projections, and in this eventuality a luster of + 1mm thick and a density of 1.2, does not poses danger to the epidermis * Cleared from measured experimentation, the innovative glazing after firing looks as follows. On the front face the laminated glass (1) is star-shaped and hollowed out at the location of the impact. the polycarbonate (3) is dented. Under this pressure, methyl methacrylate starred without loss of sensitive matter.

Les grandes diversités des cahiers oes charges ballistique font moduler les performances et l'équilibre des proportions des différents composants en fonction de la vitesse du projectile,sa masse,son profil,sa constitution,sa vitesse de rotation,sa stabilité,la densité des impacts.Vis à vis de l'explo- sion,il est nécessaire de tenir compte des pressions,de la durée de l'explosion. The great diversity of ballistics specifications modulates the performance and balance of the proportions of the different components as a function of the speed of the projectile, its mass, its profile, its constitution, its speed of rotation, its stability, the density of impacts .With regard to the explosion, it is necessary to take into account the pressures and the duration of the explosion.

Dans ces conditions,la conception sur mesure du vitrage permet de s'adapter à tous les niveaux de sécurité réclamés.La technique de fabrication du vitrage innovant est inhabituelle,mais permet d'utiliser l'équipement des fabricant/Sde double vitraqe
