This study details the damage evolution of the pinned joints for both [0/±45/90]3S and [90/±45/0]3S CFRP laminates and its difference between static and fatigue loading is discussed. Though there is no clear difference in the macroscopic external appearance of damage between fatigue and static loading failure, the microscopic internal damage shows differences in critical damage and damage evolution. In static tests all the inside 0° layers have kink at the maximum load and the kink is a trigger to the final failure with delamination and matrix crack. On the other hand, under fatigue loading the final damages start mostly from collapse or kink-like collapse at the loaded surface edge. It is also found that the total delamination length is longer in the case of fatigue at the same total matrix crack length and that [90/±45/0]3S presents higher strength than [0/±45/90]3S in both static and fatigue cases due to the band effect of 90° surface layers.
