Abstract: Adhesion of an adhesive to a surface depends on the molecular composition of the contacting surfaces. In turn, the molecular composition of the adherend surface depends not only on the underlying material composition, but on the history of the surface: how it was cured, how has it been handled and stored, what potential contaminants has it been exposed to. As a result, in order to have control over a bonding process, some sort of surface treatment is absolutely required to ensure that the surface has at a minimum been returned to a baseline state prior to adhesive application. This treatment may be as simple as a solvent wipe or removal of peel ply. In some instances, a more complex process such as abrasion or plasma treatment may be desirable. These processes are more complex in the sense that they present more opportunity to adversely affect the surface chemistry. As a result, quantitative control of these processes is critical. This paper discusses surface treatments of composite materials as a function of matrix resin chemistry.
