摘要：采用PVA纤维+钢纤维制备混杂纤维增强延性水泥基复合材料，研究了不同材料厚度、纤维掺量、纤维长度、纤维密度下复合材料的吸声性能。结果表明：当混杂纤维增强延性水泥基复合材料的厚度为120 mm、纤维掺量为6 kg/m3、纤维长度为20 mm、纤维密度不低于0.50 g/cm3时，混杂纤维增强延性水泥基复合材料的吸声性能最优。

Abstract：Hybrid fiber-reinforced ductile cement-based composite is made by PVA fiber + steel fiber，and the sound absorption performanceof the composite with different material thickness，fiber content，fiber lengthand fiber densityis researched. The results show that when the thickness of hybrid fiber-reinforced ductile cement-based composite is 120 mm，fiber content is 6 kg/m3，fiber length is 20 mm，fiber density is not less than 0.50 g/cm3，the sound absorption performance of hybrid fiber-reinforced ductile cement-based composite is the best.
