Nanometer carbon fiber is mainly classified according to the detection wave used. Stealth technology refers to the characteristics of detectable signals through controlling and reducing military targets. Generally, it can be divided into visible light stealth technology, radar stealth technology, infrared stealth technology, laser stealth technology, etc. Therefore, as a reliable means to develop radar to detect military targets in the direction of multi-function and high-performance stealth, the utilization rate is over 60%. Let's learn about the application of carbon nanofibers in wave-absorbing materials.
According to different standard radio wave absorption materials, the classification is also different. According to the forming process and carrying capacity of radio wave absorption materials, they can be divided into coated radio wave absorption materials and structural radio wave absorption materials; According to the principle of radio wave absorption, they can be divided into absorption type and interference type.
The requirements for wave-absorbing materials are getting higher and higher, mainly including thickness, density, wave-absorbing band and wave-absorbing performance. The development of the new generation of stealth weapon equipment, the former absorbent can not meet this demand, so we must find new absorbent, the development and development of new absorbent has become the focus of the research of wave-absorbing materials, generally, it is mainly with the requirements of stealth technology on the performance of wave-absorbing materials, which are constantly improving!
Carbon fiber is a typical chiral material. Chiral has no geometric symmetry between objects and their images, and no operation can make objects and images consistent. That is to say, the alternating electric field not only causes the electrode of materials, but also is synthesized by uniformly mixing randomly oriented chiral materials on a certain base material. The large characteristic of chiral materials is the cross polarization performance of electromagnetic field, it also causes magnetization of materials.
The above introduces the application of carbon nanofibers in wave-absorbing materials. As a new chiral absorption material, spiral carbon nanofibers generally show certain advantages. The radio wave absorption of spiral carbon nanofibers synthesizes the above conditions, spiral carbon nanofibers are very good radio wave absorption materials, which are easy to absorb the energy of electromagnetic waves. Then move, use other methods to release energy, and use spiral carbon nanofibers as absorption materials to better achieve the goal of radar stealth technology, among them, the current main task is the Chiral Induction and distortion of spiral carbon nanofibers themselves, which is characterized by that surface atoms are easier to be excited.
