A blast-resistant escape window for an armored combat ground vehicle has a cassette which fits within, and closes, a though-opening in a frame of a windscreen. Two releasable lever-operated locking mechanisms for releasably locking the cassette in the through-opening are mounted on the windscreen at opposite sides of the through-opening. The cassette can to be pushed out of the through-opening when the locking mechanisms have been operated to release the cassette from being locked to the windscreen, thereby providing an alternative exit for personnel in the vehicle.

A panel assembly that includes inside and outside core layers, an armor layer sandwiched between the inside and outside core layers, and an armor member that includes at least an outside portion and a transverse portion. The outside core layer includes a cut out portion defined therein. The armor layer has opposing first and second major surfaces. The outside portion of the armor member is positioned in the cut out portion of the outside core layer and the outer surface of the transverse portion is generally perpendicular to the first and second major surfaces of the armor layer.

Novel multilayer laminates and lamination methods useful for the production of safety glass are disclosed in which an interlayer is provided between substrates and a porous sealant material is provided in a strip around the perimeter of the interlayer and at least partially in-between the substrates adjacent the interlayer. The space between the substrates is evacuated or de-aired through the porous sealant. The porous sealant is then made into a non-porous, continuous perimeter seal by pressing at or near room temperature or at a moderately elevated temperature to remove pores or gaps. The laminate is further processed at higher elevated temperatures either at or near atmospheric pressure or at elevated pressure to increase the bonding between the interlayer and the substrates and to eliminate most or all of the initial texture on the surfaces of the interlayer.

A ballistic resistant material and structure and methods for allowing and preventing projectiles from passing through the ballistic resistant defense structure. The ballistic resistant defense structure involves a ballistic multilayer arrangement comprised of V-Profiles 100 which are further comprised of V-shaped wedges arranged adjacent to each other, spaced slightly apart, with gaps. The gaps between the V-shaped wedges expand or contract depending on which side of the V-Profile a projectile strikes.

The present invention relates to a (meth)acrylic polymer composition. In particular the present invention it relates to polymeric composition suitable for security glazing. The invention also relates to a process for manufacturing such a polymeric composition suitable for security glazing. More particularly the present invention relates to a bullet resistant (meth)acrylic polymer composition and relates also to a process for preparing such a bullet resistant (meth)acrylic polymer composition and its use in glazing.

Novel transparent composites have been developed that have relatively lower areal densities of conventional transparent composites, where the composites are tested for the same threat levels as specified in the NIT or STANAG standards. Particular transparent composites can withstand projectiles having relatively high kinetic energy, for example, using STANAG 4 testing conditions. Further, the novel transparent composites can withstand multiple hits using Multiple Hit Testing at a STANAG 2 threat level.

An optically detectable antiballistic plate, and a method of producing it are disclosed. The antiballistic plate includes a core of a ceramic plate, coated with a transparent fibre-reinforced surface composite layer of plastic matrix and reinforcement fibre. Cracks visible to the human eye in daylight will occur, in the event of damage to the ceramic plate.

Unidirectional ballistic glasses and methods for manufacturing the same are described herein. The unidirectional ballistic glasses, among other things, may be less susceptible to delamination resulting in greater overall life cycle and may be lighter than conventional unidirectional ballistic glasses. A unidirectional ballistic glass may include, among other things, a plurality of glass sheets that are attached to each other by one or more adhesive intermediate layers where the unidirectional ballistic glass has an exterior side and an interior side opposite from the exterior side, and the plurality of glass sheets includes an exterior glass sheet that is, among the plurality of glass sheets, nearest to or at the exterior side of the unidirectional ballistic glass, and an interior glass sheet that is, among the plurality of glass sheets, nearest to the interior side of the unidirectional ballistic glass. The unidirectional ballistic glass may further include a hydrophobic polymer layer disposed between a polycarbonate layer and the interior glass sheet, and a polyurethane layer and a polyvinyl chloride (PVC) layer that are disposed on peripheral edges of at least the interior glass sheet and the polycarbonate layer.

An kinetic object protection system for protecting a space in a building or vehicle comprising a protective barrier including one or more sheets of a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets, nets, or mesh which are secured together using a glue, heat weld, or stitching. The system may include an automated control system operably configured to cause a change in state of the barrier from a retracted state to a protective deployed state, which may include a sensing system operably configured to detect a threatening event, wherein the sensing system upon sensing the threatening event triggers the barrier to transition from the retracted state to the deployed protective state such that in the protective state, the barriers are adapted to be resistant to penetration by the kinetic objects such as vehicles.
