Abstract
In this paper, rotating-bending fatigue tests for short carbon-fiber reinforced poly-ether-ether-ketone (CFRPEEK) were carried out to investigate the fatigue characteristics of plain and notched specimens at room temperature. The fatigue mechanism in the composite was clarified through successive surface observations using the plastic replica method. The results were compared with those of poly-ether-ether-ketone (PEEK). In the case of the PEEK, the fatigue crack growth rate was very high and the fatigue strength was very sensitive to a notch. In the case of the CFRPEEK, the fatigue crack growth rate was much lower than that of PEEK, and the fatigue strength was much more insensitive to a notch than that of PEEK. The fatigue crack initiated from near the fiber end, and propagated in the circumferential direction after it grew to some extent along the fiber.
