The bond slip relationship between the fiber reinforced polymer (FRP) and the concrete interface is the foundation for the FRP to reinforce the stress analysis of the reinforced concrete. This paper adopts vacuum assisted molding technology (VARI) production of FRP slab and affixed to the concrete surface, designed 8 single lap joint shear test comparison of FRP-concrete interface bond properties, the effects of concrete strength, bond length, thickness and adhesive layer thickness on the bond behavior between FRP and concrete interface technology VARI the analysis of local shear stress law of the development of various FRP strain and the VARI test process based on control factors. The local bond shear stress slip relationship curves of the FRP- concrete interface are calculated.
