Sea-water effects on adhesively bonded CFRP and steel double strap joints

Abstract

Steel/CFRP double-strap joints adhesively-bonded by epoxy were tested in tension after exposure to 2, 4, 6, 9 and 12 months in sea-water at two different temperatures of 20°C and 50°C. Although the joint failure mode did not change within the investigated exposure time, significant reductions in joint strength and stiffness were found and these reductions appeared to correlate with the moisture uptake into the adhesive. A model was developed to predict the strength and stiffness degradation of the joints in sea water and the results compared well with the experimental results.
