Embodiment 1

[0026] A radar infrared stealth integrated composite stealth tarpaulin comprises a camouflage layer (1), a radar infrared stealth layer (2) and a base layer (3) sequentially from outside to inside. The radar infrared stealth layer includes silicon carbide fiber cloth, polyaniline composite layer and infrared stealth coating, and its total thickness is 0.6mm. In the infrared stealth material, the film-forming material accounts for 30%, the reflective seasoning accounts for 60%, and the heat storage and heat preservation microcapsules account for 10%. According to the GJB 2038A-2011 radar absorbing material reflectivity test method, the radar infrared stealth integrated composite stealth tarpaulin prepared by this method is tested, and the results show that the reflectivity is above -8dB at 3.8~12.5GHz, and the maximum is -34.3dB .

Abstract

The invention discloses radar stealth and infrared stealth integrated stealth tarpaulin and a making method thereof. The radar stealth and infrared stealth integrated stealth tarpaulin and the making method thereof are mainly used for achieving stealth of modern weapons such as vehicle-mounted guided missiles, tanks and aircrafts and improving the survival capacity, the defense penetration capacity and the deep strike capacity of the weapons. The integrated stealth tarpaulin comprises a camouflage layer, a radar and infrared integrated stealth layer and a base layer in sequence from outside to inside. The radar and infrared integrated stealth layer is formed by polymerizing silicon carbide fiber cloth and aniline in situ and has not only the wave absorption stealth performance but also antistatic property, high temperature resistance and flame retardant property. The surface of a radar absorption layer is coated with an infrared wave absorbing coating in a coating finishing mode. The tarpaulin is cut and sewn in a three-dimensional mode according to different application types. The integrated stealth tarpaulin can achieve the functions of radar stealth and infrared stealth at the same time, and has the advantages of being antistatic, flame-retardant, high in mechanical strength, flexible, wash-resistant and breathable, and convenient to produce.

Description

technical field [0001] The invention belongs to the field of wave-absorbing materials, and in particular relates to an integrated composite stealth tarpaulin with radar infrared stealth and a preparation method thereof. Background technique [0002] With the rapid development of military detection technology and precision-guided weapons, various military targets such as missiles, tanks, and aircraft are more and more likely to be quickly tracked and attacked by the enemy. On the future battlefield, the survivability of military targets and The penetration capability of weapons and equipment has been challenged unprecedentedly, and stealth technology has become the only technical means to solve the above problems. [0003] Stealth technology includes radar stealth, infrared stealth, laser stealth, visible light stealth, and sound wave stealth. At present, the main research and development objects of stealth technology are radar stealth and infrared stealth, and integrate them...
