摘　　要：研究了纳米CaCO_3和矿纤维对聚氯乙烯(PVC)复合材料力学性能的影响。结果表明,在硬质PVC复合材料中填充材料的形状对PVC复合材料的力学性能影响较大,纤维状的矿纤维比球状的纳米CaCO_3作为填充材料对硬质PVC复合材料的力学性能明显要高;而在软质PVC复合材料中,填充材料的形状对拉伸性能的影响较小。Mechanical properties of PVC composites filled by nano-CaCO3 and mineral fibres were studied respectively. The results indicate that the mechanical properties of rigid PVC composite materials are strongly dominated by the shapes of fillers, and mechanics properties of rigid PVC composites materials filled by mineral fibres are obvious higher than those of rigid PVC composites filled by nano-CaCO3. However, the shapes of fillers are less influence on the tensile properties in flexible PVC composite materials.
