Transport industries look for CO2 impact reduction of their vehicles driven by the future environmental standards. A way to reach this goal is by replacing metallic parts by lighter composite parts. The prediction of the performance of the composite products remains a challenging task during the design process. The “micro-meso-macro” approach is often used to predict the composite products. Homogenization rules are applied to transfer results between levels. This method however reaches its limits when the homogenization rules do not apply anymore. A micro-structure based modelling method is proposed to overcome this limitation. Validation of the method is done by comparing stiffness and strength results to experimental determined properties. The performance of the structural parts is then predicted by a Finite Element simulation showing the applicability of the method.
