Definitions
- the invention relates to the field of glazing for land, air and water vehicles subjected to stresses which may be of mechanical origin (pressure, impact, etc.), thermal or thermomechanical.
- stresses which may be of mechanical origin (pressure, impact, etc.), thermal or thermomechanical.
- the vision zone allowing the pilots or passengers to have a view of the exterior of the vehicle is interspersed with structural zones belonging to the vehicles and forming support zones for fixing the glazing.
- the vision zone is cut off by several parts incorporating structural uprights thus limiting the vision zone.
- window frames incorporating fasteners.
- a first drawback is the reduction in the area of vision: the occupants of the device have a relatively small area of vision due to the size of the structural elements. The areas are all the more reduced when the glazing is framed, which must include the fixing elements (screws, rivets, etc.) between the glazed areas.
- a second drawback is the increase in mass: from a mechanical stress point of view, we have changes in sections, materials and neutral fiber position (zero stress zone), making it necessary to size the glazing and the structure with a considerable thickness so that the whole can withstand the different stresses.
- the mass of the sub-assembly is strongly impacted.
- a third drawback is the increase in assembly/disassembly times: the operation times are lengthened because each glazing must be mounted in its housing. The more glazing, the longer the operations. [0006]There is therefore a need to provide a single assembly process for producing the structure and the glazing, the whole being integrated during the laminating/autoclaving operation of the entire transparency.
- a laminated glazing comprising at least a first and a second elementary transparent laminated panels juxtaposed by their edges, the respective glass sheets of which are distinct and separated from each other, characterized in that the glass sheets of the first panel on the one hand, the glass sheets of the second panel on the other hand, are bonded two by two by an intermediate adhesive layer which is integral to the surface of the assembly of the first and second panels, and in that in a juxtaposition zone of the first and second panels, a structuring element is inserted into the intermediate adhesive layer.
- Laminated glazing is made in several parts (panels).
- a structuring element is integrated into the glazing during its lamination, so as to be superimposed on at least one zone of edges or adjoining edges of two neighboring panels (juxtaposed), over a certain width on either side of these adjoining edges .
- the material and the dimensions of the structuring element are chosen so as to enable the laminated glazing to withstand the various loading cases to which it is subjected.
- the structuring element may break without however giving rise to a safety problem, the various panes of the glazing also being linked by one or more layers or sheets of polymer material, in particular spacer adhesives.
- the structuring element provides the rigidity of the connection of the sub-assembly, the elements in polymer material the resistance of the assembly in the event of failure of the structuring element.

- PC polycarbonate
- PET poly(ethylene terephthalate)
- PU polyurethane
- the (each) intermediate adhesive layer is made of polyvinyl butyral (PVB), thermoplastic polyurethane (TPU), ethylene-vinyl acetate copolymer (EVA) or ionomer resin such as poly(acrylic acid) partially neutralized with a polyamine.
- PVB polyvinyl butyral
- TPU thermoplastic polyurethane
- EVA ethylene-vinyl acetate copolymer
- ionomer resin such as poly(acrylic acid) partially neutralized with a polyamine.
- At least the first and the second transparent elementary laminated panels each consist of at least three sheets of glass bonded two by two by an intermediate adhesive layer which is integral to the surface of all of the first and second panels, and in a zone of juxtaposition of the first and second panels, a structuring element is inserted in at least two intermediate adhesive layers (at two levels of thickness of the laminated structure), in all or not of these at least least two intermediate adhesive layers.
- the structuring element extends over the entire juxtaposition zone of the first and second panels. These terms designate a continuous zone extending over the entire length of juxtaposition of the edges of the two panels, for example in accordance with a band.
- the structuring element extends over a part or several separate parts of the zone of juxtaposition of the first and second panels.
- the structuring elements When several structuring elements are inserted in this juxtaposition zone in intermediate adhesive layers at different levels of thickness of the laminated structure, they can extend independently of each other over the entire zone (length) of juxtaposition of the edges of the two panels, on only one part or on several separate parts of this juxtaposition zone.
- These different structuring elements can be made of identical or different materials, identical or different dimensions in the thickness of the laminate or in the plane of its two main surfaces, so as to be more or less superimposable, or on the contrary. distinct. Mechanical strength as well as aesthetic effects can result from these different modes.
- the laminated glazing comprises at least a first, a second and a third transparent elementary laminated panels, up to seven in particular. At least two juxtaposition zones are then defined between two adjacent elementary panels, at least one structuring element being inserted in all these juxtaposition zones, or only in some or only one of them.
- the invention also relates to the application of a laminated glazing defined above as glazing fixed by gluing, bolting or pinching, particularly as glazing for an air vehicle, in particular drone, airplane, in particular business aircraft (in English “business jet”) or tourism, or helicopter, land vehicle, in particular road or rail, or aquatic.
- FIG. 1 is a schematic cross-sectional representation of a laminated glazing according to the invention.
- FIG. 2 is an enlarged view of the cross-section of FIG. 1 in the zone of juxtaposition of the first and the second panels.
- FIG. 3 is a front view of a double windshield intended to occupy the surface of two windshields of the prior art, separated by a vertical structural upright forming part of the cabin of an aircraft.
- a laminated glazing according to the invention comprises a first and a second transparent elementary laminated panels.
- the first elementary laminated panel consists of a first sheet of glass 1 bonded to a second sheet of glass 4 by means of an intermediate adhesive layer 7.
- the second elementary panel consists of a first sheet of glass 2 bonded to a second sheet of glass 5 by the intermediate adhesive layer 7 which is made in one piece over the entire extent of the first and the second panel.
- the first sheets of glass 1, 2 of the first and second panels are made of the same material, for example aluminosilicate glass chemically reinforced with a thickness suitable for the use of the glazing, in particular between 2 and 8 mm.
- the second sheets of glass 4, 5 of the first and second panels are also made of the same material, for example chemically reinforced aluminosilicate glass or heat-tempered soda-lime glass with a thickness of between 2 and 8 mm, or poly(methyl methacrylate) (PMMA ), polyurethane (PU) or polycarbonate (PC) thickness between 3 and 16 mm.
- PMMA poly(methyl methacrylate)
- PU polyurethane
- PC polycarbonate
- the intermediate adhesive layer 7 is made of polyvinyl butyral (PVB) with a thickness of between 0.38 and 8 mm, if they are made of polymer material, the intermediate adhesive layer is made of thermoplastic polyurethane ( TPU) thickness between 0.5 and 10 mm.
- edges or edges of the first and second elementary panels define corresponding profiles allowing them to be joined perfectly as shown.
- a structuring element 8 is embedded in the intermediate adhesive layer 7 only in the juxtaposition zone of the two panels, in accordance with a band on either side of their juxtaposition profile (delimitation between the two panels).
- the structuring element 8 is transparent in chemically reinforced glass, for example 1 to 2.5 mm thick, or metal 0.5 to 4 mm thick, or in thermosetting resin reinforced with glass or aramid reinforcing fibers , 0.7 to 3 mm thick.
- the first, respectively second sheets of glass 1, 2, respectively 4, 5 of the first and second panels are connected in a sealed manner by a seal 3, respectively 6 in optionally transparent deformable, compressible polymer material, such as polyurethane , silicone or polysulfide.
- FIG 3 we see a windshield of relatively large area, the complete outline of the first glass sheets 1, 2 outer first and second panels constituting the entire laminated windshield, as well as the joint 3 connecting these first sheets of glass 1, 2.
- the joint is very thin and discreet with respect to the entire surface of the windshield.
- the invention thus makes it possible to increase the field of vision of the user, pilot, passenger, by eliminating or reducing the use of structural uprights forming part of the bodywork/cabin of the vehicle, or of mounting frames separating glazed surfaces in a partial and fractional way.
- the invention on the contrary, provides relatively large and fully transparent surfaces, free of intermediate structural support uprights for fixing the glazing. The assembly and disassembly of these is simplified and faster.
