Abstract

The invention relates to a high-temperature-resistant radar and infrared compatible stealth coating and a preparation method thereof. The high-temperature-resistant radar and infrared compatible stealth coating is of a layered structure, and sequentially comprises a metal bonding layer, a ceramic wave absorbing layer, a chip resistance type high-temperature periodic structure layer, a ceramic isolation layer and an infrared low-emissivity frequency selective surface layer from inside to outside; and the chip resistance type high-temperature periodic structure layer is a high-temperature resistance coating which is arranged in a periodic characteristic mode, and the infrared low-emissivity frequency selective surface layer is a high-temperature conductor coating which is arranged in a periodic characteristic mode. According to the radar and infrared compatible stealth coating, integration of the radar stealth function and the infrared stealth function is effectively achieved, the coating has both the radar stealth effect and the infrared stealth effect, and the defects that a traditional radar stealth coating cannot be compatible with the infrared stealth function, and the wave absorbing performance is not ideal are overcome; and the preparation method is simple and relatively mature, and is easy for large-scale production and application.

Description

technical field [0001] The invention belongs to the field of high-temperature stealth materials, and in particular relates to a high-temperature resistant radar and infrared compatible stealth coating and a preparation method thereof. Background technique [0002] Stealth technology is a method that uses various technical means to change or reduce the detectable information characteristics of the target, so as to minimize or reduce the probability of being discovered by the opponent's detection system, thereby improving the survival and penetration capabilities of the target. Generally, stealth technology is mainly divided into two categories: shape stealth technology and stealth material technology. Stealth material technology is relatively easy and has little impact on the target's shape, aerodynamics, and strength performance. However, with the rapid development of multi-spectral detection technology, a single stealth technology can no longer meet the application requirem...
