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.
