Investigation of the bond behavior of flax FRP strengthened RC structures through double lap shear testing

摘要

This paper focuses on the characterization of the bond behavior of adhesively bonded Flax Fiber Reinforced polymers (FRP) to concrete substrate. An experimental investigation has been done comparing flax and glass FRP bonded to concrete using a double shear test configuration. Flax composites appear to show the same interface behavior as the usual synthetic fiber reinforcement. Analyses of the strain and shear stress distribution along the interface reveal behavior differences.
