The hottest national nano center and Airbus jointl

The national nano center and Airbus jointly research new aviation materials

now 52% - 53% of the weight of an aircraft, or more than 80% of the volume of an aircraft, are carbon fiber composites. Compared with traditional aluminum alloy materials, it can greatly reduce the weight of the aircraft, but make it brittle. Recently, the national nanoscience center of the Chinese Academy of Sciences and Airbus (Beijing) Engineering Technology Center signed a cooperation agreement in Beijing to jointly tackle a series of problems, such as nano modification of carbon fiber composites to enhance toughness

a generation of materials, a generation of aircraft. The invention and application of carbon nanocomposites have brought about a revolution in the aviation industry. However, there are still some problems to be solved in the application of this composite material. In addition to poor toughness, electrical conductivity is also reduced. According to Zhang Zhong, a researcher at the national nanoscience center, the service life of an aircraft is about 30 years, and each aircraft has to withstand a big lightning on average. Compared with aluminum alloy materials, the conductivity of carbon fiber composites is reduced. Scientists are using nano modification technology to increase the conductivity of fiber materials to deal with the big lightning that may be encountered in the "life" of aircraft

"nanotechnology, as an emerging frontier science and technology field, is changing human cognition of the objective world and will also trigger a new industrial revolution." Liuminghua, director of the national nanoscience center, said

it is understood that the two parties signing the agreement will not only carry out toughened nanocomposites and conductive nanocomposites, which the company claims is a landmark event Research Institute, but also complete cooperative research in the fields of rice health monitoring composites during the more forward-looking ground test phase of self sensing and self-healing nanocomposites and the world's largest composite aircraft, The purpose of BFF is to explore how to make breakthroughs in advanced nanocomposite technology, such as new high-performance drag reduction coating technology and ship bottom air lubrication drag reduction technology. The goal of BFF is to manufacture a 3D printing wire made entirely of recycled plastic and apply it to the field of aircraft design and manufacturing
