Adapt to absorbing materials

Author:admin   AddTime:2021-05-22

Absorbing material refers to a type of functional composite material that can absorb and attenuate incident electromagnetic wave energy, and convert the electromagnetic energy into heat or other forms of energy through the material's dielectric loss. The absorbing material is generally composed of a composite of a matrix material and an absorbing medium. So what is an adaptive absorbing material? The adaptive absorbing material generally refers to a certain vacancy in a certain darkroom, and then the one that can be filled is called the adaptive absorbing material.

Absorbing composite materials generally require the following characteristics:

1. Thin thickness and light weight. The quality of the absorbing paint is completely additional to the weapon. For example, the specific gravity of the ferrite coating is about 5g/cm3, as the layer thickness is 4mm, the coating area is 50m2, and the additional weight reaches 1000kg, which is impractical for aircraft, missiles and other weapons. In addition, too thick and heavy coatings also affect the aerodynamic characteristics of the aircraft and increase the difficulty of the coating process.



2. Bandwidth, low reflectivity. The radar working frequency band is very wide, about 1-140GH range, and it is still expanding. For stealth aircraft, the main coverage frequency band of the absorbing coating is 1-18GHz. The current work is to pursue the widest possible frequency band under the condition of attenuation ≦10dB.

3. Strong function. It is necessary to force the absorbing composite material to be used as a absorbing material as well as a structural material, with high mechanical properties, good environmental adaptability and physical and chemical properties.
