Infrared stealth material with multi-layer structure

Abstract

The invention discloses an infrared stealth material with a multilayer structure. A core layer is hydrogel, and an auxiliary layer / auxiliary layers is / are added to one side or both sides of the core layer. The hydrogel has high specific heat capacity, and can absorb a large amount of heat on the premise of no significant change in temperature to achieve the function of heat buffering; the hydrogelserves as the core layer, so that the thermal infrared characteristics of covered objects can be reduced, and self-adaption to the environmental infrared radiation characteristics is realized to achieve infrared stealth. When the hydrogel serves as a cover, a heat-conductive fixing device is arranged on the edge of the infrared stealth material, and is communicated with a heat conducting layer toachieve controllable directional heat conduction; radar wave absorbing materials can be composited on any layer of the multilayer structure, and an infrared radiation and camouflage layer can be prepared at the outermost layer, so that infrared, radar wave and visual stealth is realized at the same time; the multilayer structure can be lined with breathable fabric to meet the air-permeability requirements of soldiers during long-time hiding. The infrared stealth material with high infrared, radar and visible-light stealth capability has the advantages of simple preparation process, low cost,portability and multifunction.

Description

technical field

[0001] The invention relates to a flexible material with a multilayer structure, in particular to an infrared stealth material with a multilayer structure. Background technique

[0002] In the field of military operations, infrared reconnaissance and surveillance technology has become more and more mature and has become an essential military technology, making it difficult for conventional trees and night to cover combatants. The current conventional method is to cover the human body with low-heat radiation blankets and other auxiliary materials to realize infrared stealth and avoid infrared detection. However, as time increases, the surface of the shelter will still appear higher than the surrounding environment, so it is easy to be detected by infrared detection equipment. Detect and expose the target. Recently, several reports have disclosed fabrics or systems that achieve long-term infrared stealth. However, the preparation process of some stealth fabri...
