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.
