Fiber texture for manufacturing fan blades made of composite material

The invention relates to a fibrous texture (10) for forming a fibrous reinforcement of a turbine engine blade formed from a composite material, comprising a reduced stiffness zone (24) having weft threads made from second fibers having an elongation at break greater than a first elongation, the reduced rigidity region extends in a longitudinal direction (DL) from the strut region and up to a height less than or equal to 30% of the height, between a first region (23) extending a length (21) from an edge (16) of the texture intended to form a leading edge and a second region (25) extending a second length (22) from an edge (17) of the texture intended to form a trailing edge, in a transverse direction (DT). 本发明涉及一种纤维织构(10)，该纤维织构用于形成由复合材料形成的涡轮发动机叶片的纤维增强件，包括刚性降低区(24)，刚性降低区具有由第二纤维制成的纬线，其具有大于第一伸长率的断裂伸长率，刚性降低区沿纵向方向(DL)从支柱区延伸并直至小于或等于高度的30％的高度，沿横向方向(DT)在第一区(23)和第二区(25)之间延伸，第一区从织构的意图形成前缘的边缘(16)延伸一长度(21)，第二区从织构的意图形成后缘的边缘(17)延伸第二长度(22)。
