The effect of CaCO 3 (calcium carbonate) ratio on the mechanical properties of CaCO 3 /PVC (polyvinyl chloride) composites was studied by numerical simulation in this paper. The representative volume units of CaCO 3 /PVC Composites with different CaCO 3 ratios were established by using the random dropping method. The stress-strain variation of CaCO 3 /PVC composites with different CaCO 3 ratios under tensile or compressive loads was calculated, and the influence of CaCO 3 ratio on the stiffness of CaCO 3 /PVC composites was discussed. Considering the comprehensive effect of calcium carbonate ratio on stiffness and stress-strain, the best ratio of calcium carbonate in PVC is 25%.
