In the present investigation the fatigue behaviour of carbon fibre reinforced plastic laminates under realistic service loading conditions has been examined. Laminates with different lay-up sequences have been tested for fatigue under spectrum loading with three different peak load levels. The damage in the laminates was characterized by using ultrasonic C-Scan as well as dynamic mechanical analysis and the damage mechanism was analyzed using scanning electron microscope. A similar investigation was also conducted on laminates with a hole. The results indicate that the spectrum loading did affect the modulus and fibre/matrix interfacial properties of all type of laminates investigated and also caused delamination in the laminate with a hole due to stress concentration around the hole.
