Abstract

The invention discloses an infrared stealth composite material based on frequency selective surfaces. The infrared stealth composite material is of a layer structure and sequentially comprises a target surface layer, a first intermediate medium layer, a capacitive frequency selective surface layer, a second intermediate medium layer, a metal capacitive frequency selective surface layer and a resistive capacitive frequency selective surface layer from inside to outside. The high-temperature-resistant infrared stealth composite material can resist the high temperature of at least 1000 DEG C and has good high-temperature resistance and excellent oxidation resistance.

Description

technical field [0001] The invention belongs to the technical field of frequency absorbing materials, and in particular relates to an infrared stealth material based on a frequency selective surface and a preparation method thereof. Background technique [0002] With the rapid development of multi-spectral detection and guidance technology, single-function stealth materials can no longer meet the needs of equipment development. Multi-band compatible stealth materials, especially infrared stealth composite materials, have become the development direction of stealth materials research. However, there are still some contradictions in realizing the integration (that is, mutual compatibility) of materials and infrared stealth functions. The reason is that radar stealth requires strong absorption and low reflection of electromagnetic waves, while infrared stealth requires low absorption and high reflection. Therefore, how to solve the contradiction between the two through materia...
