Fibrous texture to make a blower blade in composite material

摘要

The invention relates to a fibrous texture (10) intended to form the fibrous reinforcement of a turbine engine blade made of composite material comprising a fibrous reinforcement densified by a matrix, characterized in that it comprises a zone of reduced stiffness (24) comprising son or warp strands in second fibers having a second elongation at break greater than the first elongation at break, the zone of reduced stiffness extending in the longitudinal direction (DL) from the stilt zone and up to a height less than or equal to 30% of the height of the blade, extending in the transverse direction (DT) between a first zone (23) and a second zone ( 25), the first zone extending over a first length (21) from a first edge (16) of the texture intended to form a leading edge, and the second zone extending over a second length ( 22) from a second edge (17) of the texture intended to form a trailing edge.
