Results of an experimental program are presented in which two dissimilar types of structural adhesives were cured by electron beam techniques and then exposed to air at 350 degree F, water, JP-4, and acetone, respectively, during 500 hours. The aging degree was determined by changes in lap-shear strength. Adhesives tested were based on modified acrylic and polyimide. It is demonstrated that the thermosetting modified acrylic adhesives for bonding 7075-T6 aluminum-alloy specimens can be radiation cured at a moderate dose (10 Mrad) to provide lap-shear strengths of approximately 2000 psi in most cases. The thermosetting modified polyimide adhesives studied can be radiation cured but require a somewhat higher dose (20 Mrad) to achieve optimum cure. The lap-shear strengths for these were only in the range of 360 to 460 psi for bonded 7075-T6 aluminum alloy specimens.
