Laser machining of the plastic reinforced with carbon fiber by means of fiber laser

The article considers the application of laser machining for cutting the plastic reinforced with carbon fiber. The study shows that the decrease of heating effect during CFRP laser cutting is one of the high-priority tasks. In this regard, we investigate the impact of laser cutting modes on the heat-affected zone. In the laser machine we have used a high-powered fiber laser Yt — YAG, equipped with the special optical system. In order to define the optimal parameters of the machining process we have used such data as the cut count, the energy required for the unit of length and the achieved quality of cutting. The article also examines the multiple-pass process and the heat-affected zone expanding dependency on the cut count. We provide the parameters of the machining modes and give some recommendations concerning the process organization and running.
