  • Patent number: 3953630
    Abstract: A laminated transparent assembly suitable for use as a windscreen for a high speed vehicle, e.g. an aircraft or railway locomotive, comprises a load bearing sheet of toughened glass having a second sheet of glass laminated thereto by means of an impact resistant interlayer of plastics material, e.g. polyvinylbutyral, and an insert of high tensile strength flexible material which extends around the periphery of the interlayer and which has an inner part embedded in the outer marginal portion of the interlayer in a plane parallel to the surfaces of the interlayer, and an outer part extending outwardly beyond the edges of the interlayer to provide for attachment of the assembly to the structure of the vehicle. The insert is preferably a sheet of fabric material, e.g. a fabric woven from rubber-impregnated glass fibre cords and nylon, with the glass fibre cords substantially perpendicular to the adjacent edges of the assembly, embedded between layers of soft polyvinylbutyral.
