摘要：
A method is proposed to compute the macroscopic flow of non-Newtonian fluids through highly deformed woven fabrics. The method is divided in two steps. Firstly, the shear deformation of a textile reinforcement is studied from a mesoscale numerical analysis. The second step consists in simulating the mesoscale flow of the polymer through the as-deformed woven fabrics. Numerical results emphasise the drastic changes of the permeation law when the considered plain weave fabric is sheared. The influence of the flowing fluid rheology is also emphasised in case of generalised Newtonian fluids. A method is proposed to formulate the macroscopic flow law.
