Patent ID: 7288307

Claim:
A ballistic laminate comprising: a first non-woven layer comprising a plurality of two or more types of unidirectional fibers of different composition in a matrix, said fibers extending in a first fiber direction, said fibers of said first layer being arranged in a side by side relationship, said side by side relationship extending in a second direction which is transverse to said first fiber direction, said fibers of said first layer being selected from the group consisting of high molecular weight polyethylene, aramid, PBO, PBT, polyamide, polyester, and ceramic fibers, said fibers of different composition extending in an essentially periodic array in said second direction, the periodic distance between fibers of the same composition being from about the diameter of a single fiber to not greater than about 9 millimeters; a second non-woven layer comprising a plurality of two or more types of unidirectional fibers of different composition in a matrix, said fibers of said second layer extending in a second fiber direction, said fibers of said second layer being arranged in a side by side relationship, said side by side relationship extending in a second direction which is transverse to said second fiber direction, said fibers of said second layer being selected from the group consisting of high molecular weight polyethylene, aramid, PBO, PBT, polyamide, polyester, and ceramic fibers, said fibers of different composition extending in an essentially periodic array in said second direction, the periodic distance between fibers of the same composition being from about the diameter of a single fiber to not greater than about 9 millimeters said second fiber direction being at an angle relative to said first fiber direction; said first and second layers being bonded together in a stacked array.
