摘要

We report here laser cutting of carbon fiber reinforced plastic (CFRP) with an IR fiber laser (average power: 2 - 3 kW). The CFRP samples contain thermoplastic resin (CFRTP; carbon fiber reinforced thermo-plastic) or thermosetting resin as binding plastic. Well-defined laser cutting free of debris around the groove was performed for various type of CFRP plates by the laser irradiation with a fast beam galvanometer scanner on a multiple-scan-pass method. The laser-induced damage in the samples was observed and analyzed by microscopic X-ray Computed Tomography. Laser cutting with a high speed beam scanning exhibits a clean top and excellent sidewall quality along with a negligible heat-affected zone.
