Fatigue Behavior of Hercules 3501-6 Epoxy Resin.
Abstract
Plates and solid rods of Hercules 3501-6 neat epoxy resin were cast, from which tensile, compressive and torsional shear specimens were machined. Half of the tensile specimens were moisture preconditioned for six months at 65 deg C in a 98% RH environment. Room temperature static and fatigue tests were conducted, and a scanning electron microscope used to examine representative failure surfaces. Stress versus number of cycles to failure plots were prepared. Results indicate that the tensile fatigue strength is reduced by approximately 20 percent by moisture preconditioning. Cycling rate appeared to also be very important, higher rates leading to shorter fatigue lives. The failure analysis indicated shear to be a failure mode present for all three loading conditions.
