"A mathematically sound computational framework is presented for the determination of a representative volume element (RVE) of plain weave fabric composites with reinforcement imperfections. Although treated as periodic two-phase composites the imperfect geometry of such material systems often precludes a straightforward representation of the RVE in terms of a simple Periodic Unit Cell (PUC). To circumvent various limitations of simple unit cells when applied to real material systems the present contribution suggests a rigorous theoretical approach for the derivation of a reliable PUC exploiting the knowledge of the real geometry of a composite supplied by the manufacturer. It is expected that sufficient geometrical information about the real microstucture can be obtained from digitized micrographs of plain weave cross-sections that reveal the most critical imperfections caused by manufacturing processes.
