Abstract (EN): We report on the surface patterning of carbon fiber-reinforced polymer (CFRP) composites using femtosecond laser interferometry. The effect of experimental processing parameters, such as the pulse energy and scanning speed, on the quality of the patterns is studied. Using the appropriate processing parameters, a selective removal of the epoxy resin can be achieved, leaving the carbon fibers exposed and textured with the desired pattern. The period of the patterns can be controlled by changing the distance between the two interfering beams. On the other hand, the amplitude of the patterns can be controlled by changing the pulse energy or the number of laser pulses applied. In addition, sub-micron ripples are created on the carbon fibers surface allowing multiscale surface modification which may contribute to improve bonding between CFRP parts.
