摘要: The knowledge of thermal properties orthotropic layered composite materials is very important in the aeronautics industry. They can be measured with a dedicated apparatus but numerical computations develop strongly. It well known that microstructure has strong impact on calculation effective these heterogeneous materials. representative volume element (RVE) then crucial input to predict reliable results. In composites, fibre distribution often exhibits fibre-rich and fibre-poor regions. this contribution, we first investigated quantitative characterization using optical images spatial descriptors. give rise microstructural features also anisotropy. second time, defined RVEs for statistical parameters conductivities.
