The development of fatigue damage was mapped by locating a large damage site on the replica with the highest number of elapsed cycles, and relocating the same site on the previous replicas from the same set with lower number of cycles. Since the damage sites were sometimes dispersed and rare, a map with reference points such as scratches, misaligned fibres etc. had to be drawn in order to relocate the position of the fatigue damage. Moreover, repeated applications on dummy samples were done to confirm that the replica solvent did not degrade the composite surface
