Plates and solid rods of Hercules 3501-6 neat epoxy 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 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. Author
