摘要芳纶纤维具有比模量大、比强度高、韧性高等特点,能大大提高水泥基材料的性能。本文研究了短切芳纶纤维长度与体积掺量对水泥基复合材料抗折强度、抗压强度及抗冲击性能的影响,通过氮吸附测试手段研究了试件微孔结构,采用SEM观察微观形貌。结果表明:随短切芳纶纤维体积掺量或长度增加,水泥基复合材料各龄期抗折强度与抗压强度呈上升趋势,试样抗冲击性能越好,冲击剩余强度能得到更好的保留。较长的芳纶纤维(6 mm)可以更好地提升水泥基复合材料的力学性能、细化材料孔结构,在承受冲击荷载时不易破坏;过短的芳纶纤维(1 mm)对试件力学性能与抗冲击性能提升幅度有限。长度为6 mm、纤维体积掺量为4%的水泥基复合材料的综合力学性能最好,孔结构最优。

Abstract: Aramid fiber has the characteristics of large specific modulus, high specific strength and high toughness, which can greatly improve the properties of cement-based materials. In this paper, the effects of the length and volume dosage of short-cutaramid fiber on the flexural strength, compressive strength and impact resistance of cement-based composite were studied. The micropore structure of the specimen was studied by means of nitrogen adsorption test, and the microscopic morphology was observed by SEM. The results show that the flexure strength and compressive strength of cement-based composite at different ages increase with the increase of volume content or length of aramid fiber, and the impact resistance is excellent, more residual strength can be retained. Longer aramid fiber (6 mm) can better improve the mechanical properties of cement-based composites and refine material pore structure, which are not easy to be damaged under impact load. Too short aramid fiber (1 mm) has limited improvement on the mechanical properties and impact resistance of specimens. The cement-based composite with the length of 6 mm and fiber volume content of 4% has the best comprehensive mechanical properties and the best pore structure.

Key words: aramid fiber cement-based composite mechanical properties impact resistance pore structure
