The invention provides a waterproof/heat-insulation stealth integrated skin and a preparation method thereof. The core of the method lies in that the stealth performance, the heat-proof performance and the structural bearing performance are comprehensively and optimally designed, the problems of insufficient broadband wave-absorbing performance, low structural strength and the like of stealth structural materials under a high-temperature condition are effectively solved, and finally the stealth function integrated skin design is realized. The broadband stealth performance is that an electric loss type high-temperature resistant wave-absorbing structure with heat-insulating performance is designed on the outer layer of the heat-insulating stealth integrated skin through a multi-layer wave-absorbing period structure or a resistive film, so that heat insulation, temperature reduction and high-frequency electromagnetic wave absorption are realized, the working temperature of the inner layer magnetic wave-absorbing material is lower than the Curie temperature of the inner layer magnetic wave-absorbing material, and the heat-insulating/heat-insulating stealth integrated skin is finally obtained. |
