- According to the mechanical defects of polypropylene (PP), we blended modification of PP with calcium carbonate (CaCO3). We used the blends of CaCO3 and PP as the research object to test the mechanical properties of CaCO3/PP composite materials with different proportions and studied the influence that CaCO3’s content have on the mechanical properties of the composites. During the experiment, the twin screw machine and injection molding machine were used to prepare the sample of composite materials with different ratios. Then, a test had been started on the mechanical properties of composite materials. Based on the analysis of the experimental data, the results show that it can improve the impact strength under certain conditions when adding CaCO3 into PP. But, the function of tensile strength, elongation and yield strength will decrease. When the content of CaCO3 is 10% it shows better comprehensive mechanical properties. The numerical of the impact strength, the tensile strength, the yield strength and the elongation at break is 66.47kJ/m2, 11.28MPa, 9.37MPa and 873.8%. With the increase of CaCO3 content, the mechanical properties of CaCO3/PP composites will get worse.
