Abstract
A fibrous preform obtained by three-dimensional weaving, comprising a first skin, a second skin, and a central portion connecting them and forming a stiffening element. In a transverse plane, transverse threads of the first skin and the second skin are woven in pairs in the first skin and the second skin on either side of the central portion; the threads of a first pair of the first skin and of a second pair of the second skin are separated into two unitary threads at the central portion by being woven with longitudinal threads, and a thread of the first pair crosses a thread of the second pair at least twice in the central portion.
