Abstract:

Tensile specimens and T-peel specimens, which applied force normal to bond lines at a constant linear rate of failure in the bond between two bonded aluminum alloy strips, were prepared with fiberglass cloth reinforced and non- reinforced FM-47 structural adhesives. Generally, all adhesives used were pre- cured at 220 degrees F for one hour prior to bonding at 320 degrees F for one hour under a pressure of 100 psi. Various combinations of testing temperature, adhesive weights and bond line thicknesses were tested to arrive at an empirical expression which related the metal peel strength of FM-47 bonds to the mechanical properties of the resin and facings.
