Abstract
Fabricating a blade by 3D weaving a preform that is to be impregnated with resin. The visibility of the cut ends of certain yarns of the preform, e.g. the warp yarns, is accentuated in order to cause curved lines to appear, and the configuration of these curved lines is compared with a reference configuration in order to shape the preform properly.
