摘　　要：采用双层涂覆的方法制备了雷达-红外隐身兼容涂层,研究了红外隐身涂层的填料种类、含量以及涂层厚度对雷达隐身涂层吸波性能的影响,通过优化条件得到对雷达吸波性能影响最小的红外隐身涂层。实验结果表明,用双层涂覆的方法,以特殊形态片状微米级铝粉作为顶层红外隐身涂层的填料,填充量为40%,且涂层厚度达到20μm时,涂层的红外发射率可达0.15左右,其对底层雷达吸波层吸波性能的影响较小。A bilayer radar-infrared steath compatible coatings were prepared using radar absorbing coatings, which is then further coated with infrared camouflage coating. The influences of the kind and content of pigment, coating thickness on the radar absorbing performance of the coatings were systematically investigated. By optimizing the parameters, it was found that the optimum preparation conditions are as follows： pigment is Al; mass of Al is 40%; coating thickness is 20 μm, the infrared stealth coating displays low infrared emissivity value of 0.15 and the absorbing properties are hardly changed when further coated with the infrared camouflage coatings, which indicated that the bilayer paint method is feasible to get an infrared and radar compatible stealth layer coatings.
