US 5635288 · granted 1997-06-03

Abstract
A ballistic resistant composite for hard-armor application is provided. The composite includes a rigid plate, and a ballistic laminate structure supported by the plate. The laminate structure includes first and second arrays of high performance, unidirectionally-oriented fiber bundles. The second array of high performance, unidirectionally-oriented fiber bundles is cross-plied at an angle with respect to the first array of fiber bundles, and is laminated to the first array of fiber bundles in the absence of adhesives or bonding agents. First and second polymeric films are bonded to outer surfaces of the laminated first and second arrays of unidirectional fiber bundles without penetration of the films into the fiber bundles or through the laminate from one side to the other. Thus, a sufficient amount of film resides between the laminated first and second arrays of unidirectional fiber bundles to adhere the first and second arrays of fiber bundles together to form the ballistic laminate structure.

Claim 1
A ballistic resistant composite for hard-armor application, comprising: (a) rigid plate means; (b) a ballistic laminate structure supported by said plate means, said laminate structure comprising: i. a first array of high performance, unidirectionally-oriented fiber bundles; ii. 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; and iii. first and second polymeric 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 from one side to theother, whereby a sufficient amount of film resides between the laminated first and second arrays of unidirectional fiber bundles to adhere the first and second arrays of fiber bundles together to form the ballistic laminate structure.
Claims
33 totalA ballistic resistant composite for hard-armor application, comprising: (a) rigid plate means; (b) a ballistic laminate structure supported by said plate means, said laminate structure comprising: i. a first array of high performance, unidirectionally-oriented fiber bundles; ii. 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; and iii. first and second polymeric 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 from one side to theother, whereby a sufficient amount of film resides between the laminated first and second arrays of unidirectional fiber bundles to adhere the first and second arrays of fiber bundles together to form the ballistic laminate structure.
