Abstract
This paper deals with the effective conductivity tensor modelling of textile-reinforced composites (TRC). These TRC are treated as anisotropic heterogeneous media made of regular elements on which we apply a multilevel analysis that allows considering the filament-matrix mixture, the yarn and finally the unit cell scales. Moreover, the determination of the unit-cell effective thermal properties (global properties) takes into account the non-linear thermal behaviour of the constituents (local properties). In a last part, the modellings of unidirectional, 2D and 3D composites are compared to FEM solutions and experimental results in order to validate our approach.
