Abstract
The present work aims to present a methodology that applies the asymptotic homogenization technique, which lies on a rigorous mathematical foundation, combined to a simple method of real fiber arrangement identification in order to predict the elastic mechanical properties of unidirectional carbon fiber reinforced composites. The asymptotic homogenization, is implemented with support of the commercial finite element software ABAQUS. The fiber arrangement is obtained directly from micrographs of a polished cross-section sample. A simple algorithm to identify fibers and matrix from micrographs is implemented using commercial software MATLAB. The numerical prediction is then compared to the experimental results providing good agreements.
