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.
