Nanjing Fiberglass Institute launches hollow 3D fabric composite radome

The "eyes" of the aircraft also have protective glasses. On the 2019 Nanjing Innovation Week, which opened on June 26th, this black technology product from Yuhuatai District - "Hollow 3D Fabric Composite Radome" will be unveiled.

The radome is an important part of the radar. It is called the “electromagnetic window” of the radar system. It can form a closed space around the antenna to protect it from wind, sand, rain, snow and cockroaches. Also ensure that the antenna signal cannot be lost. "If the radar is compared to the eye of the aircraft, then the radome is the protective lens of the aircraft "eyes." Dr. Zhao Qian, chairman of the Nanjing Fiberglass Institute and professor-level senior engineer, said that the 3D fabric composite, strength energy It is comparable to steel, but weighs only 1/6 of the latter. Hard light is not enough. It can also meet the mechanical and thermal performance requirements of aerodynamic and pneumatic tropics in high-speed flight of radar radome.

The raw material used in the radome is somewhat similar to foam, honeycomb sandwich, hollow and breathable, and it is extremely hard to touch. Zhao Qian introduced that this material is the first reverse-interlaced structure product developed by the institute in China, and its structural design and manufacturing technology has reached the international advanced level. Due to the strict technical requirements, there are only a few major powers in China and the United States. In recent years, in addition to aircraft and ship radars, such radomes have also been used in civilian applications such as high-speed rail shrouds and petrochemical storage tanks.

Nanjing Fiberglass Institute is called Nanjing Glass Fiber Research and Design Institute Co., Ltd. It was established in 1964 to cooperate with the "two bombs and one star" strategy. It is the only comprehensive research institute engaged in the research, development, production and application of glass fiber and its products. In 1999, it became one of the first reformed research institutes in the country. As the "national team" in the field of materials in China, Nanjing Fiberglass Institute has won the National Science and Technology Progress Award for many times. In the process of promoting the construction of innovative cities in Nanjing, the innovative vitality of Nanjing Fiberglass Institute was further stimulated. Zhao Qian said that the products to be exhibited in the 2019 Nanjing Innovation Week are one of the many “black technology” achievements of the institute. The institute will build on its advantages in technological innovation , system innovation and industrial development for many years and play a leading role in leading enterprises. , to gather relevant industrial clusters and integrate into local economic and social development.
