FIBROUS TEXTURE FOR MAKING A BLOWER BLADE OF COMPOSITE MATERIAL

摘要

The invention relates to a fibrous texture (100) intended to form the fibrous reinforcement of a turbomachine blade (2) made of composite material, the texture being in one piece and having a three-dimensional weaving, the texture comprising a foot part d blade (110), a blade blade portion (120) and a blade stilt portion (130). The blade stilt part comprises a first zone (131) extending transversely from a first edge (101) of the texture intended to form a leading edge and a second zone (132) which s' extends transversely from the first zone to a second edge (102) of the texture intended to form a trailing edge, the first zone comprising warp threads or strands in second fibers different from the first fibers, the second fibers having an elongation at break greater than that of the first fibers, the first zone having a first volume ratio in son or strands in second fibers strictly greater than a second volume ratio in son or strands in second fibers in the second zone.
