Abstract:
The premise of this paper is that the properties of the resin layer between surface-mounted fiber-reinforced polymer (FRP) materials and a concrete substrate are critical factors in determining bond strength. Theoretical models for FRP delamination and cover delamination are presented. The results of bond characterization tests and beam tests are presented to verify the models. It is concluded that significant improvement in bond strength can be achieved with proper design of the bond layer. The models can be used for the design of surface-mounted FRP reinforcement.
