Abstract
To make an annular fiber structure, a strip-shaped fabric (,), is used which is made up of two superposed unidirectional sheets, with the directions of the sheets forming opposite angles relative to the longitudinal direction of the strip, the two sheets being bonded together so as to form deformable elementary meshes, the fabric being wound while being deformed so as to transform it into a flat helix, the elementary meshes deforming in such a manner that variation in mass per unit area between the inside and outside diameters of the turns remains small, and the flat turns are pressed against one another.
