Abstract: This invention discloses woven materials in which the constructed woven materials have a myriad of desired two- and three-dimensional shapes. The invention specifically discloses woven materials that are constructed by continuously varying the density and/or direction of the warp and/or weft fibers or yarns, as well as their angle of contact, at will during the mechanical weaving process. These two- and three-dimensional woven materials can also be used as reinforcers of variously shaped flexible or rigid composite materials.

Abstract: A continuously woven web includes a first woven region interwoven with a plurality of yarns to define a first weave pattern and a second woven region forming a continuous weave with the first woven region and having a continuation of the yarns. The yarns are attached to the second woven region at a distal end thereof. The second woven region has a length defined by a length between a first end positioned adjacent a termination of the first weave pattern and the distal end. In the second woven region, the yarns have a greater elasticity in aggregate and a shorter length than the second woven region. Upon application of a tensile force to the webbing, the yarns in the second woven region may elongate to a length limited by the length of the second woven region.
