Aging Performance of Epoxy Adhesive in Salt Water

Abstract:

Article Preview

In this paper, the aging of an epoxy adhesive which is used to aluminum- aluminum composite 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 the adhesive and enhance water ingress ability in the adhesive. Shear strength tests indicate that the durability of the adhesive in salt water aging is lower than that in water. IR spectroscopy and SEM of the adhesive indicates that the salt water diffusion speed in the epoxy adhesive/ aluminumaluminum composite joints depends on not only temperature but also salt water aging time, and high temperature can accelerate the degradation of the adhesive in salt water.
