Abstract

The invention discloses an aircraft anti-radar stealth material and a preparation method thereof, and belongs to the technical field of functional materials. The stealth material comprises a reflecting layer and an absorbing layer which are sequentially arranged from outside to inside, and the reflecting layer is prepared from, by weight, 30-70 parts of epoxy resin and 10-35 parts of aluminum foil and gold scraps. The aircraft anti-radar stealth material is of a double-layer structure, the outer reflecting layer and the inner absorbing layer both have good wave absorbing capacity, and the anti-radar stealth capacity of the material is greatly improved.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to an aircraft radar-proof stealth material and a preparation method thereof, and more particularly to an aircraft and ship anti-radar stealth material and a preparation method thereof. Background technique [0002] With the rapid development of modern military detection technology, the concealment of military facilities and weapons has become increasingly difficult. Among the many detection methods, radar is one of the most widely used and most effective reconnaissance methods for detecting targets. [0003] Radar stealth technology is a method of reducing the radar cross-sectional area (RCS) by weakening, suppressing, and deflecting the intensity of radar echoes, and reducing the probability of the target being discovered. It is an interdisciplinary system engineering technical method. It involves: (1) Shape design to minimize radar scattering cross-section and therm...
