The relevant geometrical parameters obtained from images of real microstructure are provided by a powerful image analyzer Lucie. Furthermore, the periodic character of a fiber-tows arrangement, typical for woven composites, reduces the basic geometrical model to a certain periodic unit cell. Two specific unit cells linked to two different homogenization approaches are introduced.  When subjected to suitable periodic boundary conditions, the homogenized unit cells can be periodically extended to map the effective elastic properties over the macroscopic domain under consideration.
