  • Publication number: 20110168005
    Abstract: The subject of the invention is: the use for a transparent bullet-proof and/or splinter-proof laminate, of which at least part of the thickness consists of a mosaic comprising at least two transparent constituent elements, in order to limit deterioration of the laminate beyond one of said at least two constituent elements that receive an impact; such a laminate with dimensions greater than those that are the maximum possible for a plate of monocrystalline sapphire, of which at least part of the thickness consists of an at least partly transparent mosaic, and of which at least one of its outer faces consists of a continuous transparent sheet; glazing for a building or transport vehicle comprising this laminate.

  • Patent number: 7908958
    Abstract: The invention relates to a ballistic resistant laminated structure comprising at least three glass sheets (1, 3, 5) a polycarbonate sheet (11) which are bound by adhesive layers (2, 4, 10) and a shielding insert (20), wherein a space delimited by said insert (20), the end face of the sheet (5) and the edge of the sheet (11) are provided with a material (30, 31) for absorbing the energy of a projectile. Said materials (30, 31) are embodied in the form of an yielding material (30) for degassing during assembling said stricture and an encapsulating material (31). A highly ballistic resistant glazing for a building or a transport vehicle comprising the inventive structure is also disclosed.

  • Patent number: 5637363
    Abstract: A laminated glass pane having at least one rigid glass sheet and one flexible plastic material sheet is described, which has a peripheral strip disposed over at least a part of the edge of the pane over at least one edge of a flexible plastic sheet. The peripheral strip has two layers of respectively different materials, a first layer designated the "internal layer", is comprised of a material having a softening temperature which is less than or equal to the temperature employed in autoclaving the sheets which are components of the pane, and a second layer designated the "external layer", is comprised of a material having a softening temperature which is greater than the temperature employed in autoclaving the sheets.
