Description
"Vitrage pare-balle permettant le tir de riposte et son procédé de fabrication"
Ce vitrage est caractérisé en ce qu'il comprend, en allant de la face du vitrage permettant le tir de riposte vers la face opposée de vitrage résistant à l'impact d'un projectile, au moins une feuille d'un polymère choisi dans les groupes des polycarbonates et des méthacrylates, une couche de résine méthacrylate et au moins deux épaisseurs de verre séparées par une couche de résine méthacrylate."Bullet-proof glazing allowing retort fire and its manufacturing process"
This glazing is characterized in that it comprises, going from the face of the glazing allowing the firing of riposte towards the opposite face of glazing resistant to the impact of a projectile, at least one sheet of a polymer chosen from the groups of polycarbonates and methacrylates, a layer of methacrylate resin and at least two thicknesses of glass separated by a layer of methacrylate resin.
Suivant une autre caractéristique de l'invention, du côté de la face permettant le tir de riposte, le vitrage comporte plusieurs feuilles d'un polymère choisi dans les groupes des polycarbonates et des méthacrylates, ces feuilles étant séparées chacune par une couche de résine méthacrylate. According to another characteristic of the invention, on the side of the face allowing the retort fire, the glazing comprises several sheets of a polymer chosen from the groups of polycarbonates and methacrylates, these sheets being each separated by a layer of methacrylate resin .
Suivant une autre caractéristique, les épaisseurs de verre comportent des lignes séquentes déterminées par une modification de la structure de ces épaisseurs de verre. According to another characteristic, the glass thicknesses comprise sequential lines determined by a modification of the structure of these glass thicknesses.
Suivant une autre caractéristique, les couches de résine de méthacrylate sont obtenues par coulage de la résine dans un espace lamellaire formé entre les feuilles ou épaisseurs de matériau adjacentes, cet espace lamellaire étant délimité à sa péri phérie par un joint d'un matériau souple dont l'épaisseur correspond à l'épaisseur de la couche de résine de méthacrylate à obtenir. According to another characteristic, the layers of methacrylate resin are obtained by pouring the resin into a lamellar space formed between the sheets or thicknesses of adjacent material, this lamellar space being delimited at its periphery by a joint of a flexible material of which the thickness corresponds to the thickness of the methacrylate resin layer to be obtained.
L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints dans lesquels
- la figure 1 est une vue en coupe schématique d'un vitrage conforme à l'invention,
- la figure 2 est une vue en coupe d'un autre mode de réalisation de ce vitrage,
- la figure 3 est une vue de dessus d'une épaisseur de verre entrant dans la construction du vitrage pare-balle des figures 1 et 2.The invention is shown by way of non-limiting example in the accompanying drawings in which
FIG. 1 is a schematic sectional view of a glazing according to the invention,
FIG. 2 is a sectional view of another embodiment of this glazing,
FIG. 3 is a top view of a thickness of glass used in the construction of the bullet-proof glazing in FIGS. 1 and 2.
La présente invention a en conséquence pour but la réalisation d'un vitrage pare-balle qui de l'un de ses côtés arrête les projectiles tels que ceux provenant d'une arme de poing ou d'une arme de guerre alors que de son autre côté il se laisse traverser par les projectiles provenant de telles armes. The present invention therefore aims to achieve bulletproof glazing which on one of its sides stops projectiles such as those from a handgun or a weapon of war while its other side it lets itself be crossed by projectiles from such weapons.
Ce vitrage permet donc les tirs de riposte de façon par exemple que l'occupant d'un véhicule blindé puisse riposter et se défendre vis-à-vis d'agresseurs extérieurs au véhicule, le tir de riposte s'effectuant sans modification de la trajectoire du projectile. This glazing therefore allows retaliation shots so that, for example, the occupant of an armored vehicle can retaliate and defend themselves against aggressors outside the vehicle, the retaliation fire being carried out without modifying the trajectory. of the projectile.
En outre, le vitrage conforme à l'invention permet, du fait de sa construction, de ne pas être détérioré lorsque ses deux faces sont portées, de manière répétitive, à des températures très différentes comme cela se produit lorsque le vitrage est placé en-plein soleil. In addition, the glazing according to the invention makes it possible, by virtue of its construction, not to be damaged when its two faces are brought repeatedly to very different temperatures as happens when the glazing is placed full sun.
Sur la figure 1 on a représenté en coupe un vitrage conforme à l'invention constituant un vitrage pare-balle classe 1 permettant de résister, par l'une de ses faces, à l'impact des projectiles provenant d'armes de poing alors que, de sa face opposée, il peut être traversé par des projectiles émanant de ce même genre d'armes. In Figure 1 is shown in section a glazing according to the invention constituting a bullet-proof glazing class 1 to resist, by one of its faces, the impact of projectiles from handguns while , on its opposite side, it can be crossed by projectiles emanating from this same kind of weapon.
Ce vitrage se compose tout d'abord, sur sa face 1 permettant le tir de riposte, d'une feuille 2 d'un polymère choisi dans les groupes des polycarbonates et des méthacrylates, cette feuille étant suivie d'une couche de résine méthacrylate 3 puis de deux épaisseurs de verre 4 et 5 séparées d'une couche de résine de méthacrylate 6. This glazing consists first of all, on its face 1 allowing the retaliation, of a sheet 2 of a polymer chosen from the groups of polycarbonates and methacrylates, this sheet being followed by a layer of methacrylate resin 3 then two thicknesses of glass 4 and 5 separated by a layer of methacrylate resin 6.
Les couches de résine de méthacrylate 3 et 6 qui assurent un assemblage par collage, sont réalisées par coulage de la résine dans les espaces lamellaires formés entre la feuille 2 et/ou les épaisseurs 4 et 5 de verre. Pour cette opération de coulage, les espaces lamellaires sont délimités à leur périphérie par un joint en matériau souple 7 tel qu'en butyral. Ce joint, d'épaisseur déterminée, constitue une entretoise définissant l'épaisseur de la couche de résine méthacrylate qui est coulée dans l'enceinte ainsi formée par un orifice périphérique formé à hauteur du joint 7. The methacrylate resin layers 3 and 6 which ensure assembly by gluing, are produced by pouring the resin into the lamellar spaces formed between the sheet 2 and / or the thicknesses 4 and 5 of glass. For this casting operation, the lamellar spaces are delimited at their periphery by a seal made of flexible material 7 such as butyral. This joint, of determined thickness, constitutes a spacer defining the thickness of the layer of methacrylate resin which is poured into the enclosure thus formed by a peripheral orifice formed at the height of the joint 7.
Cette résine méthacrylate présente la propriété de rester souple même après séchage ce qui, combiné avec la feuille de méthacrylate ou de polycarbonate 2 et les épaisseurs de verre 4 et 5, aboutit à la réalisation d'un vitrage pare-balle permettant le tir de riposte. This methacrylate resin has the property of remaining flexible even after drying, which, combined with the methacrylate or polycarbonate sheet 2 and the thicknesses of glass 4 and 5, results in the production of bullet-proof glazing allowing the retort to be fired. .
En effet, lorsqu'un projectile vient frapper la face 8 de l'épaisseur de verre 5, l'impact est amorti par la couche de résine 6 et le projectile est au pire arrêté par la seconde épaisseur de verre 4 contre laquelle l'impact du projectile est également amorti par la couche de résine 3 située sur la face opposée. Par contre, lorsqu'un projectile est tiré d'une arme de poing vers la face opposée 1 du vitrage, ce projectile transperce aisément la feuille de polycarbonate ou de méthacrylate ainsi que la couche de résine 3 et ce projectile se trouve "graissé" par cette résine méthacrylate ce qui lui permet de transpercer successivement les deux épaisseurs de verre 4 et 5. Indeed, when a projectile strikes the face 8 of the glass thickness 5, the impact is absorbed by the resin layer 6 and the projectile is at worst stopped by the second glass thickness 4 against which the impact of the projectile is also absorbed by the resin layer 3 located on the opposite face. On the other hand, when a projectile is fired from a handgun towards the opposite face 1 of the glazing, this projectile easily pierces the polycarbonate or methacrylate sheet as well as the resin layer 3 and this projectile is "greased" by this methacrylate resin which allows it to pierce successively the two thicknesses of glass 4 and 5.
Des essais ont montré que le projectile n'est dans ce cas pas dévié de manière essentielle de sa trajectoire. Tests have shown that the projectile is not in this case deviated essentially from its trajectory.
Afin d'éviter que la détérioration du verre de l'épaisseur 5 et éventuellement de l'épaisseur 4, à hauteur de l'impact d'un projectile, ne se propage sur toute la surface du verre, il est prévu, conformément à l'invention, de diviser ce verre par des lignes séquentes à hauteur desquelles la structure du verre est modifiée. In order to prevent the deterioration of the glass of thickness 5 and possibly of thickness 4, at the height of the impact of a projectile, from spreading over the entire surface of the glass, provision is made, in accordance with l invention, to divide this glass by sequential lines at the height of which the structure of the glass is modified.
Cette structure modifiée du verre pourra être obtenue de manière simple en effectuant un rainage de l'une de ses faces à l'aide d'un diamant, le verre ainsi rainé subissant ensuite de préférence une opération de trempage. This modified structure of the glass can be obtained in a simple manner by performing a creasing of one of its faces using a diamond, the glass thus creased then preferably undergoing a tempering operation.
Suivant la figure 2, on a représenté un vitrage pare-balle conforme à l'invention, du type classe 4, c'est-à-dire permettant, par l'une de ses faces, de résister au tir de projectiles provenant d'un fusil de guerre. According to Figure 2, there is shown a bullet-proof glazing according to the invention, of the class 4 type, that is to say allowing, by one of its faces, to resist the firing of projectiles from a war rifle.
Dans ce cas, la feuille de polycarbonate ou de méthacrylate 2 est remplacée par plusieurs feuilles de ce genre 21 22, 23 et 24, ces feuilles étant séparées chacune par une couche de résine méthacrylate 3 32, et 33. In this case, the polycarbonate or methacrylate sheet 2 is replaced by several sheets of this kind 21 22, 23 and 24, these sheets each being separated by a layer of methacrylate resin 3 32, and 33.
Egalement, la dernière feuille de polycarbonate ou de méthacrylate 24 est séparée de la première épaisseur de verre 4 d'une couche de résine 34 légère ment plus épaisse que la couche 3 de l'exemple de la figure 1. Also, the last sheet of polycarbonate or methacrylate 24 is separated from the first thickness of glass 4 by a layer of resin 34 slightly thicker than layer 3 of the example in FIG. 1.
A titre d'exemple, les couches 3, 31, 32, 33 et 6 pourront être de l'ordre de 1 mm alors que la couche 34 présentera, de préférence, une épaisseur de l'ordre de 3 mm. By way of example, the layers 3, 31, 32, 33 and 6 may be of the order of 1 mm while the layer 34 will preferably have a thickness of the order of 3 mm.
Egalement, les épaisseurs de verre 4 et 5 seront chacune de l'ordre de 5 mm alors que les épaisseurs des feuilles de polycarbonate ou de méthacrylate seront respectivement les suivantes - feuilles 2, 4, 21 et 24 : 5 mm - feuilles 22 et 23 : 8 mm
Les deux épaisseurs de verre 4 et 5 seront également pourvues d'un rainage 8 formant des lignes séquentes définissant par exemple des carrés de façon que les fissures du verre résultant de l'impact d'un projectile dans l'un de ces carrés ne se propagent pas au-delà de ce carré.Also, the thicknesses of glass 4 and 5 will each be of the order of 5 mm while the thicknesses of the polycarbonate or methacrylate sheets will be respectively as follows - sheets 2, 4, 21 and 24: 5 mm - sheets 22 and 23 : 8 mm
The two thicknesses of glass 4 and 5 will also be provided with a groove 8 forming sequential lines defining for example squares so that the cracks in the glass resulting from the impact of a projectile in one of these squares not propagate beyond this square.
Bien entendu, dans ce cas, les rainages des épaisseurs de verre 4 et 5 sont de préférence superposes. Of course, in this case, the grooves of the glass thicknesses 4 and 5 are preferably superimposed.
La bonne fiabilité de ce verre réside également de la mise en oeuvre des couches de résine de méthacrylate disposées entre chaque épaisseur de polycarbonate, de méthacrylate et de verre afin de tenir compte des coefficients de dilatation très différents du verre, d'une part, et du méthacrylate, et du polycarbonate, d'autre part. The good reliability of this glass also lies in the use of the methacrylate resin layers placed between each thickness of polycarbonate, methacrylate and glass in order to take account of the very different coefficients of expansion of the glass, on the one hand, and methacrylate, and polycarbonate, on the other hand.
