Abstract

Abstract

The paper presents the physics and the math models of laser ablation for fiber-reinforced composite materials in consideration of the physical processes including pyrogenation, oxidation, radiation, phase transition, both inner and outer convections. By taking carbon/epoxy composites for examples, the laser ablation process is simulated, and the results agree well with the experimental results. The numerical results indicate that the inner convection plays an important role in the ablation process; the oxidation effect can be ignored during high intense laser irradiation; the ablation mass is nearly linear to laser irradiation time when the laser power density is a constant and the ablation efficiency increases with increasing power density. The parameter sensitivity is analyzed with the loss mass and the rear surface temperature at the end of laser irradiation as the object. The analysis results show that the thermal capacity and thermal conductivity have more influences on the bear surface temperature; the epoxy volume fraction has much influence on ablation mass, but its relative sensitivity decreases with increasing laser power density. Moreover, the radiation coefficient is an important factor when the laser power density is more than 1 kW/cm2, but its relative sensitivity decreases with increasing laser power density.
