A fibrous texture has the shape of a strip extending in a longitudinal direction over a determined length between a proximal portion and a distal portion and in a lateral direction over a determined width between a first lateral edge and a second lateral edge. The fibrous texture has a three-dimensional or multi-layer weaving between a plurality of layers of warp strands extending in the longitudinal direction and a plurality of layers of weft strands extending in the lateral direction, the fibrous texture including first and second longitudinal sections extending over a width from the first or second lateral edge smaller than the determined width of the fibrous texture along the lateral direction. The first and second longitudinal sections each include warp strands and weft strands constituted by carbon fibers. The fibrous texture further includes a third section present between the first and second sections.
A fibrous texture having the shape of a strip extending in a longitudinal direction over a determined length between a proximal portion and a distal portion and in a lateral direction over a determined width between a first lateral edge and a second lateral edge, the fibrous texture having a three-dimensional or multi-layer weaving between a plurality of layers of warp strands extending in the longitudinal direction and a plurality of layers of weft strands extending in the lateral direction, the fibrous texture comprising first and second longitudinal sections each extending over the determined length of the fibrous texture along the longitudinal direction and over a width from the first or second lateral edge smaller than the determined width of the fibrous texture along the lateral direction, the first and second longitudinal sections each comprising warp strands and weft strands constituted by carbon fibers, the fibrous texture further comprising an intermediate section present between the first and second sections, wherein at least a portion of the warp strands present in the intermediate section are hybrid warp strands constituted only by both carbon fiber filaments and glass fibers filaments.
A method for manufacturing a fibrous texture by three-dimensional or multi-layer weaving between a plurality of layers of warp strands extending in a longitudinal direction and a plurality of layers of weft strands extending in the lateral direction, the fibrous structure having the shape of a strip extending in the longitudinal direction over a determined length between a proximal portion and a distal portion and in the lateral direction over a determined width between a first lateral edge and a second lateral edge, the method comprising the weaving of first and second longitudinal sections each extending over the determined length of the fibrous texture along the longitudinal direction and over a width from the first or second lateral edge smaller than the determined width of the fibrous texture along the lateral direction, the first and second longitudinal sections each comprising warp strands and weft strands constituted by carbon fibers, the method further comprising the weaving of an intermediate section present between the first and second longitudinal sections, wherein at least a portion of the warp strands present in the intermediate section are hybrid warp strands constituted only by both carbon fiber filaments and glass fiber filaments.
