US Patent 5443882: Armored garment
US 5443882 · 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 an armored garment including at least one ballistic panel contained within a supporting structure of the garment for being worn on a body part, the improvement comprising aplurality of ballistic 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
