Laser cutting of carbon fiber reinforced plastic components for remanufacturing

Abstract Carbon fiber reinforced plastic (CFRP) is extensively used in automotive and aerospace industries with the aim to achieve reduction on emissions by reducing weight. Due governmental regulations reduce environmental impact waste, need for remanufacturing CFRP becoming an interesting area of application economic benefits industry. This important as manufacturing carbon a costly process more cost effective reduces dependency virgin materials. Processing meet demands, fast high-quality cuts, can impose problems conventional methods. The use multi-pass scanning technique laser cutting investigated using 1.5 kW assist gas pressure 16 bar flow rate 126 lt/min. Using technique, through cut be obtained repeating beam travel than once. advantage when compared traditional CNC, low maintenance over time due non-contact nature i.e. no wear tool at contact area. And small spot size complex shapes cut. paper determine how performs terms speed damage. Average power was carried out experimental tests. A damage below 100 µm 2.5 m/min above obtained. Thermal effects were analyzed electron microscope (SEM) optical (OM). further optimized specialist methods such double aperture nozzle trenching. trenching 10 50 µm, respectively 7.5 3.33 m/min.
