Densely woven quasi-unidirectional fabric for ballistic applications

摘要

A fabric including a first layer of high-performance unidirectional yarns and a second layer of high-performance unidirectional yarns disposed transversely to the first layer. The fabric also includes warp and fill encapsulating yarns woven around the unidirectional yarns to substantially stabilize the unidirectional yarns. The encapsulating yarns have tenacities and tensile moduli substantially less than the tenacities and tensile moduli of the unidirectional yarns. The fabric has a cover factor between approximately 0.75 and approximately 1.50.
