Effects of thermal expansion coefficients discrepancy on the CFRP and steel bonding

The long-term durability of steel structures strengthened by externally bonded carbon-fiber-reinforced polymer (CFRP) plates or sheets is a concern due to the discrepancy in the thermal expansion coefficients (CTE) between CFRP plate and steel. In the present study, the single-lap shear test was applied to study the variation of the bonding performances between CFRP plates and steel using different types of adhesive after 150, 300, and 500...
