摘要
亚麻纤维具有断裂强度高、伸长变形小、弯曲性好、扭转刚度大等特点,因此亚麻纤维水泥基复合材料是一种应用前景广阔的土木工程材料.从亚麻纤维物理化学性质、亚麻纤维对水泥基复合材料性能的影响、亚麻纤维水泥基复合材料性能改善方法3个方面系统阐述了亚麻纤维水泥基复合材料的研究现状与存在问题.提出未来发展趋势:加强用亚麻纤维替代聚丙烯纤维制备水泥基复合材料;揭示潮湿情况下亚麻纤维水泥基复合材料性能演变规律;在三轴应力、潮湿条件耦合作用下构建亚麻纤维水泥基复合材料力学损伤模型;从增加亚麻纤维本体强度、改善亚麻纤维和水泥基材料界面黏结性角度来提高亚麻水泥基复合材料的应用性能.
Abstract
In comparison to the traditional fibers,flax fiber has many features,i.e.high fracture strength,small tensile deformation,better bending and large torsion stiffness.Flax fiber cement-based materials are the civil engineer materials with the broad application prospects.The research statuses and the existing problems of cement-based materials with flax fiber were discussed from 3 aspects,i.e.the physical and chemical properties of flax fiber,the role of flax fiber on the behaviors of cement-based materials,the properties improvement of cement-based materials with flax fiber.Based on above investigation results,the following research directions were drawn:enhance the using of flax fiber to replace polypropylene fiber on cement-based materials;revel the long-term properties of cement-based materials with flax fiber at the wet conditions;build the damage model of flax fiber cement-based composite materials under the combined actions of three-axis stress and wet conditions;improve the application performance of cement-based composite materials with flax fiber through increasing itself strength of flax fiber and improving the interfacial adhesion between flax fiber and cement-based materials.
