Abstract:
Due to the increasing demand for vehicle light-weighting, chopped carbon fiber SMC(Sheet molding compound) as a promising material has attracted a lot of attentions. However, there exist few open data and researches on the property of this material as well as lack the method to predict the property. For these reasons, an RVE model for chopped carbon fiber SMC is proposed to predicting the material property.Voroni method are used to create the RVE model and fiber orientation tensor and fiber tow information for the RVE model are extracted from the different layer of material images.DIC test is also conducted to obtain the modulus of the materials.And the results of the RVE are filled into a tensile bar FEA model to compare with the experimental results,Great consistency can be seen between the model and experimental results which mean the proposed model can be used as a way to predict the property of this material.
