000015290 520__ $$2eng$$aWe propose a consistent approach for the generation of macroscale models of short fiber composites. We extract geometrical features and distribution gradients of the fibers from X-ray microtomography. Based on this data, we generate new continuous, voxel or mesh fiber geometry by Diffuse Approximation with volume conservation. Newly generated fibers are distributed in an arbitrary 3D domain. Such domain may contain inclusions in the vicinity of which, fibers position and orient themselves depending on the chemical nature of the inclusion. The observed fiber distribution gradients help to identify these fiber behaviors and distribute geometry in the new 3D domain. The method enables to extrapolate geometrical representations of microscale geometry of composite materials obtained with X-ray microtomography to provide accurate 3D mesh for macro scale numerical simulations.
