Adhesive Development for Military Bridging

Abstract

The objective of this effort was to develop a family of adhesives suited to structural bonding of U.S. Army bridge members. To be joined were: aluminum to aluminum, aluminum to composite, and composite to composite materials. The adhesives should be non-brittle, have high shear strength, high modulus, minimal change in strength and stiffness with relative humidity changes between -65 and 165 F. These structural properties should be retained after prolonged exposure to adverse environments. Processing characteristics were to include: at least one year shelf life, adequate work life, fast cure-to- handling, and insensitivity to minor processing errors. Base resins with hydrophobic properties and curatives with low-temperature reactivity were formulated using structure-property considerations.
