Carbon Fiber Reinforced Plastic (CFRP) laminate composites have superior characteristics such as high mechanical strength and lightness. However, CFRP laminate composites are not homogeneity material like metals, therefore, these show unique damage and fracture form, that is, various damages, for example cracks in base material (plastic), these in fiber bundle and interface separations in fiber bundle, affect mutually, then CFRP laminate composites lead to fracture in the end.<br>In this study, the fatigue strength of CFRP laminate composite with circular hole are examined with different temperatures, high temperature (82℃), room temperature (25℃) and low temperature (－54℃). In addition, by using the specimens with a circular hole of the CFRP laminate composite with cumulative fatigue damage, the observation of the fatigue damage progression by the soft X-Ray inspection and the optical microscope observation of the cross-section of the specimens in which the layer interface separations and the separations in the layer generate were carried out. The results are following,<br>⑴ When the maximum stress of cyclic stress is large, the case of low temperature (－54℃) showed short fatigue life compared with the cases of 82℃ and 25℃. ⑵ In case of small maximum stress, the fatigue life is longer the temperature is lower in order of 82℃, 25℃ and －54℃. ⑶ When temperature is low, although many cracks in base metal or fiber bundle generate and exist in CFRP laminate composite, these cracks are prevented from developing to the layer interface separation or the separation in layer.
