Abstract: Carbon-fiber-reinforced plastic (CFRP) is a popular material possessing great properties, such as strength, lightness, and resistance to corrosion and the environment. Important steps in the production of various parts made of CFRP are surface structuring, milling, drilling and cutting processes. Here, we propose to use ultrashort pulse lasers to achieve the high-quality, low-heat-affected-zone ablation of CFRP. We investigated the ablation efficiency dependence on the processing parameters, such as the pulse duration, pulse energy and pulse overlap. We showed that good-quality results could be achieved using just low-/mid-average-power femtosecond laser equipment. We also discuss further cutting process optimization possibilities using ultrashort pulse lasers and show the possibility of HAZ-free CFRP cutting by femtosecond laser ablation.
