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.
Claims11
A method of fabricating a blade by 3D weaving a preform in which warp yarns and weft yarns are cut at predetermined locations in order to define outlines and a volume of said preform, said preform is shaped, and said shaped preform is impregnated, the method comprising:
- ensuring that cut ends of at least some yarns are visible so as to make curved lines appear;
- comparing a configuration of the curved lines of said preform with a reference configuration;
- and
- using the result of the comparing the configurations for preparing the blade.
