Abstract

High-performance structural adhesive joints, such as those found in aerospace components, must exhibit both high initial strength and excellent durability in severe environments. These properties are largely governed by the bonding across and the stability of the metal (oxide) - polymer interphase. Modern adherend surface treatments commonly provide the required adequate strength and durability. Factors that can degrade or limit joint strength and durability are discussed along with means to improve or, at least, to prevent reduction of these properties. Finally, areas in which advances are needed: increased understanding of bonding phenomena, improved reliability of bonded joints, and minimized environmental burdens are suggested.
