Abstract : The application of absolute reaction rate theory concepts is explored as a scientific basis for establishing an accelerated testing methodology for adhesive bonded joints. Primary attention is given to the effects of time, moisture, temperature and load history. Some of the more dominant processes occurring during cure and aging of epoxy resin adhesives are identified and potential techniques for separating and monitoring the associated activation energies of these mechanisms with aging, environment and load history are discussed. Suggestions are also made for incorporating aging effects into appropriately rigorous constitutive models.
