摘要：

The bond of FRP laminates to the cast-in-place concrete is investigated. The system is comprised of prefabricated FRP profiles, made by either hand lay-up or pultrusion, and cast-in-place concrete as a core. The bond between the dry FRP and wet concrete is realized through an epoxy adhesive which is coated to the inner surface of the FRP profiles. The wet-bond behavior is characterized by JSCE pullout tests and compared to conventional dry-bond using matured dry concrete strengthened by FRP. It was found that the load-displacement curves, the strain distributions in FRP and the interfacial fracture energy of dry-bond and wet-bond specimens were closely comparable, suggesting that an appropriate bond was achieved by casting concrete directly to composite profile via an epoxy adhesive. The wet-bonding technology is crucial to the development of cast-in-place concrete structures using FRP composite profiles as externally bonded reinforcements.
