There are two protection structures for duralumin sheet, including surface anodizing and spraying ZrO2 coating, designed for preventing damage induced by laser. In this paper, for anodized aluminum sheet and ZrO2 coated sheet, the ability for laser protection has been simulated and analyzed. The thermal model of sandwich material is established and a finite element method (FEM) code is developed. The rule of the thermal effects in two structures induced by laser irradiation have been discussed, under chosen requirements of laser protection, including that laser power density is 500W/cm2; irradiation time is 3s; the aluminum sheets cannot be much thicker than 3mm; reflectivity cannot be much than 0.6. And the calculation results are verified experimentally and can give a guide to design for laser protection.
