A method of using an anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier is configured to be in a compact retracted state which can be deployed to provide a protective state to protect against kinetic ballistic projectiles. The system may include an automated control system operably configured to change the state of the ballistic barrier from the retracted state to the protective deployed state, such that upon sensing a threatening event or condition triggers a transition from the retracted state to the deployed protective state such that in the protective state. The ballistic barrier in the deployed state is configured to be resistant to penetration by high-speed ballistic projectiles such as a bullet fired from a gun or a shrapnel from a bomb to protect the interior space.

Laminates and their process of manufacture, with the laminates made with anti-ballistic materials, such as woven and unwoven fabrics. The laminates are provided with different structures, materials, bondings, and other features, and example methods of manufacturing those laminates efficiently and in mass quantities. The method of production is a process of laminating individual flexible sheets including anti-ballistic material (which may be of woven or unwoven cloth or thin solid sheets or foils comprised of one or more light-weight anti-ballistic materials) into a flexible laminate for use to protect people or spaces from ballistic objects such as bullets and shrapnel from weapons and other moderate to high-kinetic energy objects. Also, an anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes the laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier is configured to be in a compact retracted state which can be deployed to provide a protective state to protect against kinetic ballistic projectiles.

Bonded polymeric film laminates comprising core polymer film layers individually coated on at least one side with a heat fusible polymer layer and fusion bonded together by the application of heat and pressure at a temperature at which each heat fusible polymer coating bonds together adjacent core polymer film layers, where the melting point or softening temperature of the heat fusible polymer is at least 3° C. below that of the core layer polymer, and the lamination temperature is at or above the melting point or softening temperature of the heat fusible coating polymer, where the heat fusible polymer coating layers are thinner than the core polymer film layers, where the coated core polymer film layers are uniaxially stretched by 2× to 40×, and the stretched coated core polymer film layers are cross-plied. Methods for forming the laminates, coated films from which the laminates are formed, and articles formed from the laminates are also disclosed.

Protective shields configured to prevent projection against projectiles, such as during excavating and/or mining operations, are provided. The protective shields include a base layer comprising one or more transparent polycarbonate layers, a sacrificial polycarbonate layer comprising a transparent polycarbonate, and an air gap positioned directly between at least a portion of the base layer and the sacrificial polycarbonate layer. The sacrificial polycarbonate layer is directly or indirectly attached to the base layer in a manner to provide the air gap positioned between the base layer and the sacrificial polycarbonate layer.

A multi-layer structure includes a glass layer having a thickness of greater than or equal to 10 μm and less than or equal to 200 μm; and a resin layer. A number of unit lamination structures in a thickness direction of the multi-layer structure is greater than or equal to 5 and less than or equal to 20,000, the unit lamination structure being a lamination structure composed of the glass layer and the resin layer.

A blast-resistant window attachment, or retrofit window insulation system, wherein panes of polymer film, such as TPU or ETFE, are held in a roll-formed stainless steel frame to form a pane assembly. One or more pane assemblies are stacked to make a multilayer unit or are mounted in a robust polymer casing that is sized to fit the window frames of an existing building window or to attach to the wall of the building surrounding the window. The polymer film or films can absorb energy of a blast without breaking provided that the collective thickness of the film(s) is at least 20 mil, and preferably 24 mil or more. The casing is, preferably made from a high strength polymer, such as Acrylonitrile Butadiene Styrene, or a metal such as stainless steel. In experiments conducted by the Army Corp of Engineers, the retrofit window insulation system of the present invention, when securely bolted to the structural components of the building around the window, demonstrates a remarkable ability of the polymer film panes to absorb blast energy and mitigate secondary debris hazards.

An entryway door is capable of withstanding direct hit hurricane loads and subsequent water surge for long periods. A door slab is formed of reaction-injected-molded aliphatic polyurethane having an outward face, and inward face, and a peripheral edge, with a window opening formed therethrough. A ballistic glass-clad polycarbonate laminate window is provided which sized larger than the window opening. The laminate window having a central light transmissive region and an outer boarder region. A primer is applied to the outer boarder region of outward and inward faces of the laminate window. The door slab is reaction-injected-molded about the laminate window with the outer boarder region extending into and is bonded to a portion of the door slab forming the window opening. The preferred door in mounted to a structure in an outwardly opening manor with a seal entrapped between the periphery of the door and a door jam.

The present invention provides a lightweight blast-mitigating polycarbonate laminate system comprising at least one polycarbonate sheet, a portion of which is laminated to a glass layer having a thickness between 0.25 times and less than 1 times the thickness of the polycarbonate sheet. The laminate system may further include fasteners to attach the system to a building, positioned to prevent the laminate system from breaking or detaching in case of a blast event.
