Abstract
The durability of adhesive joints in hostile environments is a major area of concern in structural adhesive bonding. Therefore, understanding the mechanics and mechanisms of degradation of adhesive joints is a key factor for more extensive use in future engineering applications. In this contribution, we aim to develop a more complete understanding of failure mechanisms of an epoxy/aluminium oxide interface upon exposure to liquid water and aqueous sodium chloride (NaCl). A fracture mechanics approach based on a shaft-loaded blister test was employed to measure adhesive fracture energy of the joints. X-ray photoelectron spectroscopy (XPS), neutron reflectivity (NR), water sorption and contact angle measurements were used to elucidate mechanisms of adhesion loss.
