18 Claims

1. Ballistic laminate for ballistic protection comprising at least one first unidirectional textile element and at least one second unidirectional textile element, the first textile element comprising a first plurality of ballistic fibers arranged substantially according to a first direction, the second textile element comprising a second plurality of ballistic fibers arranged substantially according to a second direction, the first and the second direction forming a relative angle of 90°+/−10°, the laminate being covered by a first protective layer external to the first unidirectional textile element and by a second protective layer external to the second unidirectional textile element, the laminate being characterized in that it comprises a plurality of through holes having a diameter comprised between 0.02 mm and 3 mm, the plurality of through holes passing through the first and second protective layer and the at least first and the at least second unidirectional textile element, wherein the density of the through holes is between 0.1 and 10 per cm²and at least some of the plurality of through holes are stitching holes wherein a stitching thread passing through a given through hole of the plurality of through holes has a maximum diameter corresponding to 90 percent of the diameter of the given through hole.
