Experimental Evaluation of Cutting Quality of Carbon Fibre Reinforced Polymer with Pulsed Laser

Abstract:

To investigate the cutting quality of Carbon Fibre Reinforced Polymer (CFRP) with pulsed laser, experiments of high modulus CFRP were carried out using a Nd: YAG pulsed laser with wavelength of 1064nm. Experiments with five factors and five levels were designed to apply the response surface methodologies (RSM). The influence rule of processing parameters consisting scanning speed, pulse frequency, pulse energy, pulse duration and gas pressure on the morphology of machining region including the kerf width, kerf taper and the width of heat affected zone were studied, and the interactions of these input parameters on cutting qualities were also analyzed. Parameters optimization were conducted based on the mathematical model using the optimization software Design Expert. Verification experiments were carried out to prove the adequacy of the optimization results. The infrared laser with pulsed mode was found to be an effective method in processing high modulus CFRP.
