    Carbon-fiber-reinforced polymers are increasingly used especially in structural parts for new aircraft. However, laser machining is not well implemented for cutting or drilling because significant collaterals effects remain. In this paper, we propose a study of laser-matter interaction at moderate flows (<1MW/cm2) of T700 CFRP. The dynamics of the process is observed by high speed camera (200...

    The herewith presented approaches are relevant for a large range of applications were surfaces or thin films are treated by scanning processes in large scale, e.g. photovoltaics, flat panel displays production, drying and annealing surfaces. Such laser systems can be implemented into inline-processes, and efficiently replace in some technologies ...
