Abstract
The aging in water of steel/composite glass polyester specimens bonded with an epoxy adhesive has been studied at 25 degrees and 40 degrees C. The dam age processes are controlled by water diffusion. The main damage is due to the adhesive swelling but, when Specimens ari: loaded during immersion, the stress gradient at the extremities of the joint accelerates the water diff usion and-then the failure of specimens. A simple logarithmic relationship between the specimen life time and the applied load makes easy the life pre diction.
