Characterization of Adhesively Bonded Aluminum Armor through Qualitative Analytical Techniques

Abstract

Aluminum armor 5083, single lap shear coupons were joined with generic epoxy and urethane adhesive to determine the adhesive effectiveness. Chemical treatment of the aluminum substrate with Methyl Ethyl Ketone (MEK) was also examined to determine its effect on the shear strength. The tests were conducted under atmospheric pressure and a temperature of 70 degrees + or - 5 degrees F. Shear strength results indicate that, when applied to an untreated or MEK treated surface with a 60 + or - 10 microns inch finish, both epoxy and urethane are unacceptable for aluminum armor 5083 bonding.
