METHOD FOR THREE-DIMENSIONAL WEAVING OF A FIBROUS STRUCTURE WITH ORIENTATION OF WEFT COLUMNS IN A DEPLOYMENT PORTION AND RESULTING FIBROUS STRUCTURE

Abstract: in a method for three-dimensional weaving of a fibrous structure between layers of warp yarns and layers of weft yarns, the weft yarns are woven in a plurality of columns spaced apart from one another in a longitudinal direction. the method includes weaving deployment portions in the fibrous structure that is interwoven with an adjacent portion, the weft yarns of the weft yarn columns of the adjacent portion being juxtaposed in a first stacking direction perpendicular to the longitudinal direction. during the process of weaving the deployment portions, the weft yarns of each weft yarn column are positioned against the fell of the fibrous structure in stacking directions that are different from the first stacking direction.
