植物纤维增强水泥基复合材料研究进展

RRESEARCH PROGRESS ON PLANT FIBER CEMENT-BASEED COMPOSITE MATERIAL

由于植物纤维具有密度低、比强度高、可再生和经济环保等特点,近年来受到了土木工程界的广泛关注。在水泥基复合材料中掺加适量的植物纤维可以有效提高基体的抗拉强度、抗弯强度和韧性等力学性能指标。文中总结了植物纤维的分类、植物纤维增强水泥基复合材料宏观力学性能及提高复合材料耐久性能的植物纤维改性方法,并对今后植物纤维增强水泥基复合材料的发展进行了展望。

Due to the characteristics of low density, high specific strength, renewable and economical and environmental protection, plant fibers have received widespread attention in domain of civil engineering in recent years. Adding appropriate amount of plant fibers to the cement composite can effectively improve the mechanical properties of the matrix such as tensile strength, flexural strength, and toughness. This paper summarizes the research results of the domestic and abroad about the classification of plant fibers, the macro-mechanical properties of plant fiber cement-baseed composite material and the method of improving fiber for durability of cement composites.Finally the paper looks forward to the future development of plant fiber cement-based composite material.
