| 英文摘要 | A multi-scale analysis model which can reflect thermal-mechanical damage effects,such as ablation, pyrolysis and delamination within layers in the high-power continuous-wave laser irradiation of carbon fiber reinforced polymer(CFRP)laminates is built.The pyrolysis kinetic equations of fibers and matrices are derived from the meso-scale analysis,and the pyrolysis kinetic parameters are obtained from the thermo-gravimetric analysis,thereafter the macroscopic thermal-physical and mechanical property parameters of CFRP laminates are obtained.Based on the cohesive model,an analysis model is built to describe the laser induced delamination behavior within layers.Meanwhile,a thermal-resistance model is also proposed and built to describe the attenuation of thermal energy due to pyrolysis and delamination within layers.By combining the thermal-mechanical property parameters obtained from the multi-scale model with the thermal-mechanical numerical model,the ablation, pyrolysis and delamination within layers of CFRP laminates irradiated by high-power continuous-wave lasers can be simulated.The numerical results show good agreement with the experimental data. |
