建立了能够反映高功率连续激光辐照碳纤维增强复合材料(CFRP)层合板时材料发生烧蚀、热解与层间开裂等热力损伤效应的多尺度分析模型。从细观尺度分别建立了纤维和基体的热解动力学方程,通过热重分析获得热解动力学参数,进而得到CFRP层合板宏观的热物与力学性能参数。通过内聚力模型建立了激光辐照引起层间开裂的分析模型,提出并建立了热解和层间开裂效应阻碍能量传递的热阻模型。将多尺度模型获得的热-力学性能参数与热力耦合数值模型相结合,模拟了高功率连续激光引起的烧蚀、热解及层间开裂行为,模拟结果与实验结果吻合较好。 |

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. |
