Stealth materials have mature applications in the military field and are in the research and development stage in the civilian field.

Invisible materials are designed using optical and electromagnetic principles to make them indiscernible to optical, infrared and other detection instruments. At the same time, because they do not reflect light or cast shadows, they produce refracted light and electromagnetic rays, which blend with the environment and make them invisible. It is invisible to the human eye, thus achieving the invisibility effect.

According to the “2021-2025 Invisible Materials Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center, according to functions To divide, stealth materials can be divided into two categories: stealth coating materials and stealth structural materials; according to raw materials, stealth materials can be divided into ferrite materials, heterogeneous materials, composite absorbing materials, etc.; according to the detection wave spectrum To divide, stealth materials can be divided into acoustic stealth materials, radar stealth materials, infrared stealth materials, visible light stealth materials, laser stealth materials, etc.

The military field is an important application market for stealth materials, and it has been maturely used at this stage. Stealth materials are used in the military field to reduce the detection probability of equipment and weapons, improve their aggressiveness and survival rate, and can greatly improve combat efficiency. They are widely used in aircraft, vehicles, tanks, ships, and rockets, mainly using radar. Stealth materials, infrared stealth materials. From the perspective of military aircraft, stealth aircraft such as the F-22, F-35, Su-57, J-20, and F-2 have been launched globally in the United States, Russia, China, Japan and other countries. As military technology continues to advance, the number of equipment and weapons using stealth technology will continue to increase in the future, which will benefit the development of the stealth materials industry.

Compared with the military field, stealth materials are still in the research and development stage in the civilian field and have not yet been commercialized. Unlike the military field where stealth materials are mainly aimed at making detection instruments invisible, the research direction of stealth materials in the civilian field is mainly aimed at making them invisible to the naked eye. For example, manufacturing invisible clothing makes the wearer invisible in the crowd; manufacturing invisible gloves to make the doctor’s hands invisible during surgery and no longer blocking the surgical site; manufacturing invisible shells for rail transit, airplanes, etc. to improve driver observation efficiency and reduce accidents Probability etc.

In my country, the number of invisible material R&D companies is increasing, mainly including Guangqi Technology Co., Ltd., Guangdong Xinjinggang Technology Co., Ltd., Shanghai Anoqi Group Co., Ltd., Guangdong Fenghua High-tech Co., Ltd., etc.

Industry analysts said that at this stage, the application scale of stealth materials in the military field is constantly expanding. This is due to the development of stealth materials for radars. The technical difficulty is relatively low, while the technical difficulty of developing invisible materials for vision is relatively high. At this stage, in the civilian field, invisible materials have not yet been commercialized. In the short term, their market space is small, and the industry still has a long way to go in the future. In the military field, as the deployment rate of high-tech equipment such as new generation fighters and stealth submarines in the military continues to increase, the stealth materials industry has broad room for development.
