Abstract:
According to one aspect, a fabric for use in structural applications, having a first layer of structural yarns comprising first structural yarns aligned in a first direction, a second layer of structural yarns comprising second structural yarns aligned in a second direction at an angle relative to the first direction, the second layer of structural yarns disposed on top of the first layer of structural yarns, first encapsulating yarns disposed on the second layer of structural yarns, the first encapsulating yarns being aligned with the first structural yarns, and second encapsulating yarns being aligned with the second structural yarns, the second encapsulating yarns being alternatively woven above one of the first encapsulating yarns and below one of the first structural yarns such that the first encapsulating yarns and second encapsulating yarns cooperate to secure the first layer of structural yarns to the second layer of structural yarn. The first and second encapsulating yarns may have tenacities and tensile moduli substantially less than tenacities and tensile moduli of the first and second structural yarns.

Abstract:
A multi-layer fabric, having a first woven portion having warp yarns and weft yarns interwoven together to form a first woven layer, a unidirectional portion that includes a first unidirectional layer having first unidirectional yarns, the first unidirectional layer being adjacent the first woven layer, and at least one securing yarn interwoven with the first woven layer and the first unidirectional layer to secure the first unidirectional portion to the first woven portion. The fabric may have encapsulating yarns interwoven with the first unidirectional yarns to secure the first unidirectional yarns together to form the first unidirectional layer.
