The strength properties of composite matrix resins and adhesive are dependent on time, temperature, environment, and stress factors. All of these conditions combine to influence the properties of adhesives and composites in ways that are not yet fully known or quantifiable. Therefore, it is important to know the service conditions that structural adhesive bonded composite joints will encounter prior to fielding. This paper details an evaluation of five epoxy adhesives used to adhere a carbon/epoxy composite to 7075-T6 aluminum, 4340 steel and aluminum coated steel. Test results indicate that certain paste adhesives are capable of better lap-shear and peel performance than film adhesives, especially at elevated temperatures.
