Abstract
Effects of the loading direction and the fiber content on the fatigue crack growth behavior of FRPET are studied by the acoustic emission method. From the behavior of AE event count rate, the fatigue crack growth process is divided into three zones similar to the three stages of the fatigue crack growth curve. Many AE generations under the mean load phase suggest nearness to the final fracture. Three kinds of damage modes occur at all zones in a specimen for which the angle between the directions of loading and injection is 0°(parallel), but not in the specimens of 90°(perpendicular) and 45°(oblique) angles. Fiber breakage is a dominant damage mode in all zones of the fatigue crack growth process in specimens of fiber contents of 15 and 45 % by weight.
