Development of a Cohesive Model for CFRP-To-Steel Bonded Joints for Low and High Temperatures

This work analyses the impact of low and high temperatures on the bond between Carbon Fiber Reinforced Polymers (CFRP) and steel substrates. The aim of the experimental tests is to study the local and global bond behaviors of CFRP-to-steel joints under different temperature conditions. The results suggest that high temperatures are more severe for the joints than negative ones. Based on the experiments and on the data collected from the literature, a unified and updated cohesive model with temperature dependency is proposed.
