dc.description.abstract | The diffusion characteristics of water in polymer materials have been studied for a few decades. Several methods have been developed to provide water diffusion characteristics as a function of time, temperature, pressure, or thickness of polymer. Unfortunately, most of these methods give the amount of water absorbed as a function of weight versus time at given environmental conditions. Concentration profiles of the water diffusion through the polymer have been unobtainable by these established methods. Neutron radiography is a method of non-destructive testing that has grown rapidly over the past ten years and is capable of giving these concentration profiles. Epoxy is one of the most commonly used polymers for which water diffusion information is important. In the automotive industry, epoxy is used both as a sealant and a bonder to prevent water from getting inside structures and causing corrosion. To prevent this corrosion, it is important to know the diffusion behavior of water in the epoxy adhesive.p ]This paper will demonstrate the use of high resolution neutron radiography as a viable method for the determination of the diffusion profile of water in commercially available epoxies. Aluminum coupons were constructed and joined together using four different epoxies. These coupons were then submerged in water. Neutron radiographs were made of the coupons as a function of total time submerged and water temperature. The weights of the coupons were also obtained as a function of submerged time for comparison with other methods. Four different epoxies were tested. Profiles of the water concentration are easily observed and measured. | en_US |
