US Patent 5443883: Ballistic panel
US 5443883 · granted 1995-08-22
Abstract
A ballistic laminate structure in sheet form, which includes a first array of high performance, unidirectionally-oriented fiber bundles and a second array of high performance, unidirectionally-oriented fiber bundles cross-plied at an angle with respect to the first array of fiber bundles, and laminated to the first array of fiber bundles in the absence of adhesives or bonding agents. First and second thermoplastic films are bonded to outer surfaces of the laminated first and second arrays of unidirectional fiber bundles without penetration of the films into fiber bundles or through the laminate from one side to the other.

Claim 1
In a ballistic panel for preventing penetration of high-velocity bullets and fragments through the panel from one side to the other, the improvement comprising a plurality ofballistic laminate structure in sheet form assembled together to form the ballistic panel, said laminate structure comprising: (a) a first array of high performance, unidirectionally-oriented fiber bundles; (b) a second array of high performance, unidirectionally-oriented fiber bundles cross-plied at an angle with respect to said first array of fiber bundles, and laminated to said first array of fiber bundles in the absence of adhesives or bondingagents, said first and second arrays of high performance, unidirectionally-oriented fiber bundles comprising fibers chosen from the group consisting of aramid fiber, ultra high molecular weight polyethylene, high molecular weight polyethylene, highmodulus vinylon, and liquid crystal polymer-based fiber; and (c) first and second thermoplastic films bonded to outer surfaces of said laminated first and second arrays of unidirectional fiber bundles without penetration of said films into said fiber bundles or through the laminate structure from one sideto the other, whereby
