Fibrous texture for producing a fan blade made of composite material

摘要

A fibrous texture 100 intended to form the fibrous reinforcement of a turbomachine blade made of composite material, the texture being made in one piece and having a three-dimensional weaving between a plurality of warp and weft yarns of at least first fibres. The texture comprises a blade root portion 110, a blade airfoil portion 120 and blade support portion 130. The blade support portion includes a first area 131 intended to form a leading edge and a second area 132 extending from the first area intended to form a trailing edge, the first area comprising warp yarns or strands made of second fibers different from the first fibres, the second fibres having an elongation at break greater than that of the first fibres, the first area having a first volume ratio in yarns made of second fibres strictly greater than a second volume ratio in yams or strands made of second fibres in the second area.
