%X 为了减轻抗激光防护材料的结构重量，本文采用有限元方法对一种由反射层、散热层、隔热层和基板构成的复合夹层式抗激光防护材料结构进行了优化设计。仿真结果表明：随着散热层厚度的增加，激光防护层和基板的最高温度都随之降低；随着隔热层厚度的增加，基板最高温度随之降低，而激光防护层的最高温度却随之升高，且隔热层厚度对其防护性能的影响更显著。当散热层厚度为1.48 mm、隔热层厚度为0.29 mm时，结构满足防护要求，且重量最轻，为0.295 kg。<br />
In order to lighten the weight of a compound sandwich type of anti-laser protection material structure which consists of reflection layer, heat conduction layer, heat insulation layer and substrate, the structure design and optimization were proposed by using the finite element method. The simulation results show that with increasing the thickness of the heat conduction layer, the highest temperature of laser protection layers and substrate both become smaller and smaller. With increasing the thickness of the heat insulation layer, the highest temperature of substrate becomes smaller and smaller. However, the highest temperature of laser protection layers becomes higher and higher. And the thickness of the heat insulation layer has more significant effect on the protective property. When the thickness of the heat conduction layer is 1.48 mm, and the thickness of the heat insulation layer is 0.29 mm, the structure could satisfy the anti-laser protection demands and the weight is the lightest, which is 0.295 kg.
