Abstract:
The subject of the invention is the use of a transparent splinter-proof and/or bullet-proof laminate, at least part of the thickness of which is formed from a mosaic comprising at least two transparent components, in order to limit the deterioration of the laminate away from that one of said at least two components which receives an impact; such a laminate has dimensions greater than the maximum possible dimensions of a single-crystal sapphire plate, at least part of the thickness of which is formed from an at least partially transparent mosaic and at least one of the external faces of which is formed from a continuous transparent sheet; architectural glazing or automotive glazing comprising this laminate.
Abstract:
A ballistic transparency (10) includes a first ply (12) having a peripheral edge (42); a second ply (18) spaced from the first ply (12) and having a peripheral edge (46); a polymeric layer (24) located between the first ply (12) and the second ply (18); and at least one flexible mounting member (38) having a first end (52) extending within the polymeric layer (24) and a second end (54) extending beyond the peripheral edges (46,42) of the first and second plies (12,18).
Abstract:
A blast-resistant barrier comprising a plurality of units each including a panel having a thickness of greater than 20 to less than 40 millimeter is disclosed. The panel is in the form of a monolithic polycarbonate sheet or laminate that is positioned vertically between the source of a blast and the blast target, the laminate including at least two polycarbonate sheets and an optional image layer interposed therebetween. The panel is fixedly attached to a frame which is firmly embedded in concrete in a manner calculated to provide stiffness sufficient to absorb and withstand external forces resulting from said blast. In a preferred embodiment the panel includes at least two polycarbonate sheets laminated one to the other, optionally including an image layer interposed therebetween. In an additional embodiment, the frame is anchored securely to the target enabling dissipation of the blast force through the target's structure. The height of the blast-resistant barrier is preferably proportional to the height of the target.
Abstract:
A barrier that includes attack resistant pane(s) (see DEFINITIONS section). In this way, a person behind the barrier can be protected when they are outside. More specifically, the person behind the barrier is protected, at least to some extent, from both: (i) vehicular attacks; and (ii) blast (for example, bombs) and/or ballistic (for example, bullet) attacks. Also, the protected person can see what is happening across the barrier because of the attack- resistant pane(s). Also, if the barrier is unanchored then it can be moved from place to place, for example, by heavy equipment, so that the same barrier can be re-deployed at different outdoor locations (or indoor locations) on an as-needed basis. Preferably, the barrier also includes framing pieces that secure the attack-resistant pane(s) to the body of the barrier, with the framing pieces being covered on one side by an attack-resistant material (preferably, hardened steel).
Abstract:
A reinforcing fiber for reinforcing a transparent matrix composite. The fiber includes a substantially transparent fiber ribbon having an elongated cross-sectional geometry. The fiber ribbon includes edges that are substantially opaque. Light is substantially prevented from passing through the opaque edges to reduce or eliminate light distortion through the fiber. A composite utilizing the reinforcing fibers and a method for making a window assembly and a method for manufacturing a vehicle are also disclosed.

Abstract:
A laminated, optically transparent, ballistic resistant structure is described as having a first transparent layer, a second transparent layer of ceramic tiles spread across the first layer, and a third transparent layer. The first and third layers are bonded to opposite sides of the second layer, respectively, by transparent adhesive. Other embodiments are also described and claimed.
Abstract:
The invention describes a transparent glass armor having a plurality of crack arrestors. The armor may be monolithic, laminated or segmented. The crack arrestors enhance the ability of a transparent armor to absorb multiple projectile impacts without catastrophic failure or loss of optical transparency. The crack arrestors restrict propagation of cracks, and may be at non-orthogonal angles to the strike face.
Abstract:
A transparent armor laminate system is described that utilizes a glass ceramic material as the strike face material, one or a plurality of intermediate layers, and a backing material. This laminate system offers improved performance with reduced weight over conventional all glass or all-glass-ceramic transparent armor systems.
