AbstractThe bond between carbon-fiber-reinforced polymer (CFRP) and steel is crucial for strengthening of steel structures using CFRP materials. Carbon fiber reinforced plastics (CFRTP) had been widely used in aerospace [1], and automotive [2], due to their high specific strength and corrosion resistance. In coastal areas or inland lakes with high salinity, the steel bars in reinforced concrete (RC) structures are easy to rust by chloride and carbon dioxide due to the porosity of concrete, which will lead to a reduction in load-carrying capacity and durability of RC components, as well as huge economic loss. 3M’s epoxy adhesive was used to secure This study aims to investigating the interfacial bond behavior of IM and UHM CFRP plates bonded to steel using finite element analysis (FEA) and presenting a bond-slip Hyconnect combines glass and steel fibers with welding to lightweight structures. In this paper, we examine the development of the estimation models of bond strength and effective bond length for a double strap joint between carbon fiber reinforced polymer (CFRP) plate and corroded steel plate. Debonding of the CFRP plate from the steel substrate is one of the main failure modes of CFRP-strengthened steel structures.
