Abstract

There are many advantages that structural adhesives can offer compared to the more traditional joining methods, such as welding, bolting, mechanical fastening, etc. However, there are some issues that currently limit the wider application of adhesives. One of the most important issues is the limited knowledge concerning the durability of adhesive joints upon exposure to hostile environments [1]. Therefore, understanding the mechanics and mechanisms of the durability of adhesive joints is a key factor for their future extensive use in engineering applications. The aim of the present study, thus, is to develop a better understanding toward mechanisms of moisture attack. Models of adhesive joint consisting of the homologous series of poly(n-alkyl methacrylate)s (PAMA) supported on SiOx substrates were studied. This polymer series enables subtle chemistry effects on moisture-induced adhesion loss to be examined. A fracture mechanics approach based upon a shaft-loaded blister test was adapted to measure adhesive fracture energy of the joints over a wide range of relative humidity. A spectroscopic technique and contact angle measurement were used to elucidate mechanisms of adhesion loss.
