Abstract: Methods are provided for creating a component from a preform having a network of fibers having, after the shaping of the preform, an out-of-register angle. The methods include: defining an orthogonal local frame of reference, defining a natural local frame of reference, defining a linked frame of reference, expressing a tensor of the stiffnesses of the woven composite material in said natural local frame of reference, constructing a tensor of the deformations in the orthogonal local frame of reference, expressing, in the linked frame of reference, the tensor of the deformations, calculating a tensor of the stresses in the natural local frame of reference, expressing, in the orthogonal local frame of reference, the stresses tensor, expressing the stiffnesses tensor, constructing a tangent operator, establishing an optimized configuration for the network, and locally adapting the network before impregnating said network.

Abstract: A fibrous structure having the form of a band extending in a longitudinal direction (X) over a given length between a proximal part and a distal part and in a lateral direction (Y) over a given width between a first side edge and a second side edge, the fibrous structure having a three-dimensional or multilayer weave between a plurality of layers of warp yarns or strands extending longitudinally and a plurality of layers of weft yarns or strands extending laterally, wherein a first portion of the fibrous structure present between the proximal part and an intermediate part of the fibrous structure includes carbon fiber weft yarns or strands and wherein a second portion of the fibrous structure present between the intermediate part and the distal part includes glass fiber weft yarns or strands.
