Abstract:
The invention concerns an armoured, bullet-proof and/or anti-splintering laminated glass panel consisting of a stack whereof one part extends, over at least part of the glass panel periphery, beyond the rest of said stack, thereby forming a protuberance against which is pressed, on the inside if the impact is deemed to occur on the outside, an armour shield (C) made of highly bullet-resistant material, integral with the glass panel. Thus is formed a highly bullet-resistant peripheral system (BP) consisting of the protuberance and the shield (C), system by which the glass pane is mounted in the rebate of the structure designed to bear the glass panel; the rest of the glass pane consisting of a central bullet-proof system (BC). The invention is characterised in that the system (BC) comprises, in its peripheral region corresponding to that of the shield (C) of the system (BP), one or several reinforcing armouring layers (1f) made of highly bullet-resistant materials, made integral with the stack forming the glass panel, the single reinforcing armouring layer or at least one of the reinforcing armouring layers being integral with said shield (C).

Abstract:
The invention relates to: laminated glazing (1) including a first structural ply (4) attached to a first sheet of glass (2) of 0.5 to 1.5 mm in thickness by means of a first adhesive interlayer (3), said first sheet of glass (2) making up a first outer surface (21) of the laminated glazing (1), the surface of said first sheet of glass (2) directed toward said first adhesive interlayer (3) supporting a first conductive heating layer (11) of 2 angstroms of 500 nm in thickness, and said first conductive heating layer (11) having flow separation lines of 0.05 to 0.2 mm in thickness spaced 8 to 20 mm apart; and the application of this glazing as aircraft or helicopter cockpit glazing.
Abstract:
The invention relates to a glass panel essentially made up of a transparent polymer material sheet with a thickness of 5 to 25 mm and a glass sheet with a thickness of 0.5 to 1.5 mm that are adhered to each other by an adhesive insert, the hardness of which is less than or equal to 70 Shore A at a temperature greater than or equal to -5°C and the thickness of which decreases depending on the thickness of the glass sheet. An adhesive insert thickness of 2.0 mm is sufficient for a glass sheet thickness of 0.55 mm, and an adhesive insert thickness of 1.25 mm is sufficient for a glass sheet thickness of 1.25 mm. The invention also relates to the use of said glass panel for a ground, air, or water transport vehicle, the vehicle surface in contact with the outer atmosphere being made up of one so-called "glass sheet."
Abstract:
The invention relates to a glazing successively comprising: a first rigid substrate (S1); a second rigid substrate (S2); a third rigid substrate (S3); at least one active system (A) including at least one layer and provided between the substrates (S1, S2); the first substrate (S1) being optionally recessed relative to the other substrates (S2, S3); at least one polymer film having a chip-retaining function in case of glazing breakage, provided between the substrate (S1) and the substrate (S2) and between the substrate (S2) and the substrate (S3).
Abstract:
A transparent material in a monolithic or laminated sheet based on a methyl methacrylate homopolymer or a copolymer, the laminated material having at least one of its outer layers made of a methyl methacrylate homopolymer or copolymer, characterized in that the monolithic methyl methacrylate hompolymer or copolymer or the at least one outer methyl methacrylate homopolymer or copolymer layer of the laminated sheet exhibits an 0.1 to 1 g/cm3 increase in average density in the region of the surface for a depth of at least 50 nanometres from the surface, said average density being determined by X-ray reflectometry.
Abstract:
A multiple glazed insulating unit, wherein the glazed section comprises at least two superposed slabs (2; 3) made of a transparent substrate and which is mechanically resistant and involves the interpositioning of at least one gas lamina, whereby said slabs (2; 3) are mounted in the region of the periphery thereof (4) in a sealing joint (4) enabling the glazed unit (1) to fit into a structure which is designed to enclose a space containing equipment which can be disrupted by an electromagnetic field and which acts as an electromagnetic armour. The invention is characterized in that the glazed part comprises at least one thin transparent electroconductive continuous layer (5) and in that the joint (4) becomes at least partially conductive to ensure a link between said thin transparent electroconductive layers (5) and said structure, whereby the conductivity of said thin transparent electroconductive layers (5) and the joint (4) are chosen in such a way that the electromagnetic armour of said structure remains continuous.
