Abstract: A method for improving the translation efficiency of fiber strength into composite strength is provided. A single unidirectional tape, single unidirectional fiber web or a stack of unidirectional web/unidirectional tape plies formed from partially oriented fibers/tapes is primed under mild conditions followed by subjecting the primed plies to an axial extension stress in the axial fiber direction of each fiber ply by passage through a compression apparatus.

Abstract: This invention relates to the use of an open, plain Leno Aramid fiber weave wrapped around the armor base plate in such a fashion that the wrap on the strike face surface is bonded with a thermoset resin while the continuous fibers around the back are left resin-free and able to distort, allowing localized deformation while keeping the remainder of the “wrap” holding tight. This wrap technique keeps the composite backing tight to the strike surface while allowing all of the benefits of localized fiber movement and tensile failure on the backside of the target. Other high performance fibers, such as fiberglass, also woven in a Leno weave and applied in the same method will yield similar results. This invention also relates to the placement of a “slip layer” between the fiber surface and the polymer coating of an armor system.
