Definitions
- Aeronautical heated windshields are laminated sheets of at least three sheets (or folds) of mineral and / or organic glass, the outermost of which can support the heating function (defrosting). These sheets are bonded two by two via intermediate adhesive layers such as polyvinyl butyral (PVB), thermoplastic polyurethane (TPU), ethylene-vinyl acetate (EVA), ionomer ... Moisture can penetrate the intermediate adhesive layers , in particular that between the heating external fold and its neighboring fold and causing failures by different mechanisms:
- PVB polyvinyl butyral
- TPU thermoplastic polyurethane
- EVA ethylene-vinyl acetate
- Moisture can penetrate the intermediate adhesive layers , in particular that between the heating external fold and its neighboring fold and causing failures by different mechanisms:
- heating layers such as indium oxide doped with tin (Indium Tin Oxide - ITO -) (inducing a cracking of the layers which can be the cause of an electric arc near the layers);
- the external fold not being naturally held by the connection system to the airplane (which maintains the two structural folds), due to the deformations of the glazing subjected to the pressure of the airplane, of the tear-off mechanisms. and / or peripheral shearing of the external fold can take place, which promotes delamination phenomena.
- Moisture penetration can be managed by different strategies:
- a sealing element typically of the two-component polysulphide or polyurethane (PU) type;
- peripheral step element or Z - "zed" - metallic (stainless steel, aluminum) glued, conforming to a peripheral zone of the laminated glazing, as will be seen later; this zed is glued to the glass sheets of the laminated glazing and can be covered by an air and water seal, such as silicone or equivalent, as well as by a "drop" (external seal in polysulfide or equivalent) providing aerodynamic continuity between glazing and aircraft structure and good inertia to aeronautical fluids (cleaning products, glycol (defrosting ground)...) ; moreover the drop also makes it possible to significantly limit the problems linked to arcs and sparks, in particular the collection of electric arcs and surface discharges.
- peripheral barrier elements in tiers called “zed” in stainless steel (or sometimes aluminum) has greatly reduced the penetration of humidity and has thus been able to largely eliminate the failure modes mentioned above. .
- cables run at the level of the zed between the outer fold and the inner face of the glazing;
- the inventors therefore sought to replace the metallic zed with a zed made of polymer material which can be shaped, for example, by a thermoforming process.
- the polymer material was chosen to have sufficient water vapor permeability properties to prevent degradation of the glazing.
- specific permeability P is understood to mean the permeation rate of 1 mm of material.
- the fluxes are then expressed in g / m 2 / day.mm and express the barrier performance against the intrinsic water vapor of a material.
- the water vapor barrier performance of a given material or combination of materials (of given thickness) is its permeability p expressed in g / m 2 / day.
- the invention relates to a laminated glazing comprising at least a first sheet of glass constituting an outer face of the glazing, connected to a second sheet of glass by a first intermediate adhesive layer, in which the edge of the first sheet of glass is set back from that of the second, a peripheral part of the free surface of the first sheet of glass, the edge of the latter, the edge of the first interlayer adhesive layer and part of the surface of the second sheet of glass projecting from the first sheet of glass describing a continuous stepped outline which is covered by a stepped element with interposition of glue, characterized in that the stepped element is made of polymer material which may contain reinforcing fillers, and has a permeability to water vapor at most equal to 5, and preferably 1 g / m 2 / day.
- glass is meant here both a mineral glass such as soda-lime, aluminosilicate, etc., as well as an organic glass made up of a transparent structural polymer material, including poly (methyl methacrylate) (PMMA) and polycarbonate (PC). are common examples.
- PMMA poly (methyl methacrylate)
- PC polycarbonate
- the metallic step elements do not cause any water vapor permeation through their thickness, but a bypass path via glue (polysulfide) exists. Due to the greater flexibility of the step elements made of polymer material, it is possible to reduce the thickness of glue and to make these step elements equivalent in terms of permeability to water vapor to the bonded metallic step elements.
- thermoforming are substantially less expensive than stamping metals
- the polymeric materials have a flexibility making the sensitivity of the relative shapes of the step element and the laminated glazing more easily manageable in production and limit the bonding stresses which can cause detachment of the step element in service.
- Said adhesive comprises, for example, a polysulphide and / or a polyurethane.
- the tiered element is integral, in one part, or possibly in several parts.
- the step element has an elastic modulus at most equal to 5GPa; it should be emphasized that this excludes polymers (such as thermosetting resins of the epoxy type, unsaturated polyester) reinforced with reinforcing fibers (FRP of English “fiber reinforced polymer”), which designates a reinforcement by fibers (such as glass or carbon) relatively long, possibly woven;
- polymers such as thermosetting resins of the epoxy type, unsaturated polyester
- FRP of English “fiber reinforced polymer” which designates a reinforcement by fibers (such as glass or carbon) relatively long, possibly woven
- polymer material is chosen from polyolefins (including polyethylene (PE), polypropylene (PP) or polyisobutylene (P-IB)), polyvinyl chloride and its derivatives (for example poly (vinyl dichloride) (PVDC)), styrenic polymer (e.g.
- polystyrene PS
- ABS acrylostyrene butadiene
- SAN styrene acrylonitrile
- PAN polyacrylonitrile
- PMMA poly (methyl methacrylate)
- PET poly (ethylene terephthalate)
- PBT poly (butylene terephthalate)
- POM polyoxymethylene
- PA fluoropolymer
- PCTFE polychlorotrifluoroethylene
- PCTFE polycarbonate
- PC aromatic polysulfone including polysulfone (PSU), polyphenylene ether ( PPE), polyurethane and polyurea (PU), epoxy (EP) alone or as a mixture and / or copolymer of several of them;
- the step element is composed of several layers of identical or different polymeric materials, which can be obtained by coextrusion for example;
- Said polymer material contains oriented lamellar reinforcing fillers and / or short fibers; these charges are such as to promote a sufficiently low permeability to water vapor; mention may be made of short glass or carbon fibers;
- the step element has a thickness at most equal to 800, preferably 300 ⁇ m;
- said polymeric material has at least one surface treatment providing ⁇ better barrier performance against water vapor: dense oxide (s) deposited by chemical vapor deposition CVD such as S1O2, AI2O3;
- - Said adhesive has a thickness at most equal to 350, preferably 200 ⁇ m;
- the tiered element is covered by an air and water seal, and protection against solar radiation and fluids; this seal is advantageously made of silicone or equivalent;
- the tiered element is covered by a drop which provides the laminated glazing with aerodynamic continuity between glazing and mounting structure such as aircraft structure and good inertia to processing fluids such as aeronautical fluids, cleaning products, degreaser, glycol for ground defrosting and the like; this drop may be made of polysulfide or equivalent;
- the laminated glazing comprises at least a third glass sheet connected to the second glass sheet by a second intermediate adhesive layer; in this configuration in particular, the step element can extend beyond said continuous step contour defined above, so as to cover the entire thickness of the laminated glazing, including the edges of the second sheet of glass, the second intermediate adhesive layer and the third glass sheet;
- the first glass sheet is made of mineral glass with a thickness of between 0.5 and 5, preferably between 2 and 4 mm, or of a polymer material such as poly (methyl methacrylate) (PMMA) with a thickness of between 0 , 5 and 5 mm;
- PMMA poly (methyl methacrylate)
- the second glass sheet, and where appropriate the third glass sheet, or even the following sheets, are made of mineral glass with a thickness of between 4 and 10 mm, or of a polymer material such as poly (methyl methacrylate) (PMMA) d 'thickness between 5 and 30, preferably at most 20 mm;
- PMMA poly (methyl methacrylate)
- said intermediate adhesive layers are made of polyurethane (PU),
- the thickness of the first intermediate adhesive layer is between 3 and 10, preferably 4 and 8 mm, and the thickness of the second intermediate adhesive layer and where appropriate, the following is between 0.5 and 4, preferably at most equal to 2 mm.
- Another object of the invention consists in a method of manufacturing the laminated glazing described above, characterized in that the step element is produced separately from its mounting structure by thermoforming, injection, injection molding and RIM reaction ( reaction injection molding), extrusion or coextrusion, blowing, compression-transfer.
- the composite tiered elements (resin reinforced with fiberglass) formed directly on the laminated glazing are designed for good evacuation of gases during the curing stage of the resins (reticulation in an autoclave or vacuum bag). This good ability to drain gases is antagonistic with good moisture barrier performance (porosity effect).
- the step element is made in one or in several parts.
- Another object of the invention consists in the application of the laminated glazing described above as glazing for buildings, land, air or water vehicles, or for street furniture, in particular as cockpit glazing for air vehicles.

- the edge of the first sheet of glass 1 is set back relative to that of the second 3, a peripheral part of the free surface of the first sheet of glass 1, the edge of the latter 1, the edge of the first adhesive layer interlayer 2 and part of the surface of the second glass sheet 3 projecting from the first glass sheet 1 describing a continuous step contour which is covered by a step element 7 of polyethylene terephthalate (PET) of 355 pm d 'thickness.
- PET polyethylene terephthalate
- step element 7 Said continuous step contour is covered by the step element 7 with the interposition of a thickness of 100 ⁇ m of glue 6 made of polysulphide.
- step element 7 is covered by a seal 8 for air and water sealing, in silicone, and by a drop 9 in polysulphide which provides the laminated glazing with aerodynamic continuity between glazing. and mounting structure such as aircraft structure and good inertia to the processing fluids as already explained.
- the step element 7 may be more extended than shown, so as to cover for example the entire peripheral edge of the laminated glazing, in particular also the edges of the second sheet of glass 3, of the second interlayer adhesive layer 4, and the third glass sheet 5.
- equivalent barrier corresponding to a fictitious material covering exactly the thickness of interlayer on the periphery of the glazing.
- the water vapor permeation properties of the equivalent barrier are then defined by
- the replacement of a step element 7 made of metal by a step element 7 made of PET is capable of giving a permeability p lowered by 0.87 to 0.67 g / m 2 / day on the one hand, from 0.91 to 0.68 g / m 2 / day on the other hand.
- the deformable polymer material more easily follows the shape of the glazing without mounting constraints. Its use makes it possible to reduce the thicknesses of glue from 500 ⁇ m or 1 mm to 100 ⁇ m, hence the possibility of reducing the value of the permeability p relative to the metallic zed (step element) 7.
- the non-metallic zed eliminates all the drawbacks linked to the electroconductivity of metals, as expected.
- the manufacturing costs are lower for the polymer material, in particular by thermoforming, than for metals, especially with regard to tooling.
