Abstract

This paper describes the use of dielectric spectroscopy as a nondestructive method for monitoring first solvent ingress at elevated temperatures within aluminum adhesively bonded joints, and second, water uptake within carbon-fiber reinforced plastic (CFRP) bonded joints. Dielectric measurements were carried out in both frequency and time domains, allowing for changes in the dielectric permittivity and loss to be calculated.
