Abstract：To understand the deterioration mechanism of CFRP/steel interface properties under extreme hot and humid environment,12 of CFRP/steel double lap specimens using Sika-30 adhesive were prepared.These specimens were immersed in simulated seawater at 70℃for different time for tensile shear test.The results show that the failure mode of these specimens were less affected by the soaking time.The average shear strength of the CFRP/steel interfaces increased first and then decreased with the soaking time.After soaking for 90 days,the average shear strength of the CFRP/steel interfaces decreased by 35.6%compared with that of unsoaked specimen.
