Notes:
In this paper, the aging of an epoxy adhesive which is used to aluminum- aluminumcomposite joints in medium was studied by infrared spectroscopy (IR), scan electronic microscope(SEM) and shear strength test. In salt water, Na+ and Cl- can accelerate hydrolyzation of theadhesive and enhance water ingress ability in the adhesive. Shear strength tests indicate that thedurability of the adhesive in salt water aging is lower than that in water. IR spectroscopy and SEMof the adhesive indicates that the salt water diffusion speed in the epoxy adhesive/ aluminumaluminumcomposite joints depends on not only temperature but also salt water aging time, andhigh temperature can accelerate the degradation of the adhesive in salt water
