Abstract (en)

[origin: WO2022185007A1] A fibrous texture (200) for a blade has a three-dimensional weave between a first plurality of layers of filaments (201) and a second plurality of layers of filaments (202). The texture comprises a blade airfoil part (205) extending between a first edge (205a) and a second edge (205b) The texture comprises a first part (212) with at least three layers of filaments of the first plurality of filaments and at least three layers of filaments of the second plurality of filaments. Filaments of the two layers of filaments of the first plurality of filaments (201) bind filaments of the second plurality of filaments (202) to the two layers of filaments of the second plurality of filaments with a determined binding frequency.
