Fiber texture for a casing made of composite material with improved impact resistance

A strip-shaped fibrous texture 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 strip-shaped fibrous texture having a three-dimensional or multi-layered weaving between a plurality of layers of warp yarns or strands extending in the longitudinal direction and a plurality of layers of weft yarns or strands extending in the lateral direction,

• wherein the strip-shaped fibrous texture comprises a first section extending along the longitudinal direction over a determined length from the proximal portion and in which one or more layers of the plurality of layers of weft yarns or strands consist of a plurality of groups of weft yarns or strands, each group of weft yarns or strands comprising at least (a) one carbon fiber yarn or strand and (b) one glass fiber yarn or strand, said at least (a) one carbon fiber yarn or strand and said (b) one glass fiber yarn or strand of each group of weft yarns or strands being woven together in pair following an identical weaving path, the strip-shaped fibrous texture further comprising a second section present along the longitudinal direction between the first section and the distal portion of said strip-shaped fibrous texture in which the layers of the plurality of weft yarns or strands consist of carbon fiber yarns or strands.
