Abstract:In order to reveal the mechanism of energy absorption and transfer of materials in laser cutting of carbon fiber reinforced plastics (CFRP), a three dimensional finite element model for parallel laser cutting of single-fiber arranged CERP, a three dimensional fiber-spot diameter ratio model and a three dimensional fiber-resin double phase model are established, respectively. Numerical simulation results show that, with the decline of fiber-spot diameter ratio, the kerf width decreases from 229.45   m to 95.60   m, while the width of the heat affected zone (HAZ) decreases from 172.08   m to 156.79   m. The experimental results agree well with the simulation results, and the errors for the kerf width and the HAZ width are 5.97% and 1.13%, respectively. ? 2017 Universitat zu Koln. All rights reserved.
