Abstract

The interface properties between fiber and matrix predominantly influence the mechanical performance of fiber reinforced cementitious composites (FRCCs). In this study, the interface between polyvinyl alcohol (PVA) fibers and mortar was modified by coating graphene oxide (GO) on the fiber surface. Experimental results showed the GO@ PVA fibers improved the tensile strength of FRCCs by 35.6% compared to that of pristine PVA FRCCs. Theoretical analysis indicated this significant improvement was attributed to the enhancement of the chemical bond energy (G_d) at fiber/matrix interface. With GO surface modification, the G_d was increased more than 80 times, changing the failure mode at the interface from adhesive failure to cohesive failure.
