Description
Summary:Since the use of carbon fiber reinforced polymer (CFRP) becomes widespread, exploration of thermal damage is of vital concerns when it is subjected to high-energy laser (HEL) irradiation. In this study, the effects of the high-energy laser parameters on hole dimensions such as hole diameter, hole depth, carbon oxidation diameter, epoxy damage diameter, and heat affected zone (HAZ) diameter are investigated. The numerical modeling is developed with COMSOL Multiphysics® using Heat Transfer in Solids and Deformed Geometry interfaces to study a transient temperature field and the thermal damages. The removal of the material by the heat of ablation is modeled through a combination of deformed geometry and phase change approaches. Since CFRP undergoes different thermal events and pyrolysis, the present model is developed by incorporating the appropriate material properties at different thermal events and decomposition of resin through a modified Arrhenius equation. Multiple reflections between the carbon fibers are also taken into account to accurately predict the damage in the target material. In the end, the present numerical model is validated with the experimental results by measuring hole depth, hole diameter, carbon oxidation diameter, epoxy damage diameter, and HAZ diameter. From the results, it is seen that the developed numerical model could fairly predict the damages and the model predictions are in good agreement with the experimental data.
