Study on Properties and Applications of Dielectric Absorbing Materials for Ultra-lightweight Microspheres
In order to achieve lightweight absorbing materials,this paper designs the microstructure and synthesis method of the material to combine the dielectric properties of carbon materials with the low characteristics of hollow structures,and prepared carbon hollow sphere(C@air)material has execellent wave absoroption properties with ultra-lightweight.Based on this material,absorbing plates and absorbing honeycomb cores that can be used for the leading edge of stealth aircraft wings are prepared,and electromagnetic simulation and radar reflection cross-section(RCS)testing are conducted on them,the horizontal polarization in the same direction reaches-32.3 dB,and the vertical polarization in the same direction reaches-27.2 dB.It is verified that the material has excellent absorbing performance and application effect,and provides ideas for the design and application of absorbing materials.
