Zusammenfassung:	An integrally woven three-dimensional preform with stiffeners in two or more directions constructed from a woven fabric having a first, second and optional third woven fabric layer. A plurality of yarns are interwoven over a region between the first and second fabric layers such that the first fabric layer is foldable relative to the second fabric layer. An additional plurality of yarns are interwoven over a region between the second and third fabric layers such that the third fabric layer is foldable relative to the second fabric layer. Upon folding of the woven fabric layers, the integrally woven three-dimensional preform with stiffeners in two or more directions is formed.
