Laser cutting of carbon fiber reinforced plastics (CFRP) by fiber laser irradiation

Laser cutting of carbon fiber reinforced plastics (CFRP) with a cw IR fiber laser (λ= 1090 nm, average power: 1kW). A well-defined cutting of CFRP which was free of debris and thermal-damages around the grooves, was performed by the laser irradiation with a fast beam galvanometer scanning on a multiple-scan-pass method.
