摘要：

The fatigue life of microcellular polycarbonate specimens of five different relative densities ranging from 0.52 to 0.97 was measured in tension-tension tests on dumbbell specimens. Fatigue life varied with relative density and maximum nominal cyclic stress. The fatigue life of microcellular polycarbonate with relative foam density of 0.97 exceeded that of solid polycarbonate by over 400 percent. Fatigue life decreased with decreased relative foam density.
