【Abstract】 This paper discusses the property of heat insulation of composite heat shields made from ablative layer and heat insulation layer manufactured from heat insulation material. Through the property test, the result indicates that these two kinds of composite heat shields can depress the coefficient of heat conductivity and thermal diffusivity. So the heat shields can be used in spaceflight engineering.更多还原
