摘要：
A new type of nano-silica modified polypropylene fiber was prepared. The mechanical properties of fiber were tested and the distribution of nano-particles on the fiber surface was observed with SEM. This paper focuses on the mechanism of improving fiber-matrix interfacial properties, especially the dispersion of modified fiber and crack resistance and their effects on mechanical properties of fiber reinforced mortar(FRM) and fiber reinforced concrete(FRC). The results demonstrate that the modified fiber with well-distribution of nano-silica has good mechanical properties, and shows excellent dispersion and crack resistance. The interfacial property of fiber-matrix is improved and the compressive and flexural strength of FRM and FRC is increased to some extent.
