CA 2746708

The invention relates to the manufacture of a vane by 3D weaving a preform to be impregnated with resin. According to the invention, the visibility of the cut ends of some yarns of the preform (16) is accentuated, for example the warp yarns, to reveal curved lines (20), and the configuration of said curved lines is compared with a reference configuration to ensure correct the shaping of the preform.
