 The application of nanomaterials will become the "new darling" of aircraft
The “modification” of carbon fiber with nanomaterials enhances the toughness and electrical conductivity of aircraft and enhances the safety performance of aircraft. It is regarded as a major direction for the next generation of aviation materials. Recently, the Suzhou Institute of Nanotechnology and Nano-Bionics of the Chinese Academy of Sciences officially signed a cooperation agreement with Airbus (Beijing) Engineering Technology Center and announced the establishment of the "Aeronautical Nanomaterials Joint Laboratory". The two sides will take the market as the direction and accelerate the application of nanomaterials in civil aircraft. This is the first time that Airbus has signed strategic cooperation with China in the nano field.

As one of the world's largest passenger aircraft manufacturers, Airbus has always represented the most advanced level of large aircraft manufacturing. Its "star passenger aircraft" - Airbus Civil Aviation A350 has gradually replaced traditional materials such as metal and fiberglass with carbon fiber materials. "In use, it has been found that carbon fiber also has its own limitations, such as low toughness and poor electrical conductivity. The strength of carbon nanomaterials is 10 times that of carbon fiber, and the advantages are obvious." Researchers at Suzhou Nanotechnology Institute told reporters that nanomaterials can be modified. Carbon fiber, such as nano-infiltration, can improve conductivity and protect aircraft safety and passenger comfort in the face of lightning and other impacts.

Looking at the world, the application of nanomaterials in aviation is generally in the "experimental" stage. Marketization is the biggest intention of Airbus and Suzhou Nano. The self-contained “grain and grass” joint construction laboratory has clear demand for Airbus. "We need to modify carbon fiber through nano-materials, and rapidly form scale and industrialization, further reduce the weight of the aircraft and improve the safety and comfort of the aircraft." Cheng Long, chairman of Airbus (Beijing) Engineering Technology Center, told reporters that this time Before signing the contract, I once sought a “solution” on a global scale, and finally landed at Suzhou Nano Institute, which is a “high efficiency” that emphasizes the transformation of technology here.
 
In the pavilion of Suzhou Nano, the carbon nanofilm is placed in the most conspicuous position, and looks like a thin black paper at a distance, very thin. According to reports, it has been applied in the field of equipment manufacturing. For example, a jacket in the exhibition hall can be quickly "charged" by adding carbon nano materials, which is convenient for users to travel and inspect in extremely cold places.

"To meet the needs of economic development and strengthen the integration of technology and industry, it is the responsibility of the Institute of Nanotechnology of the Chinese Academy of Sciences." Yang Guishan, president of the Nanjing Branch of the Chinese Academy of Sciences, said that the establishment of laboratories by both sides is complementary to each other and wins "paradigmatic" cooperation between the two sides. template. It is reported that the cooperation has been supported by Yu Jianyong, an academician of the Chinese Academy of Engineering, Huang Yonggang, an internationally renowned mechanic, and Zou Zuwei, an internationally renowned nanocomposite expert. The three experts will work together to ensure the smooth progress of the project.

In Suzhou Industrial Park, it is not uncommon for enterprises and institutions to jointly build "joint laboratories". Innovative cooperation mechanisms to promote the transformation of decentralized scientific research into a complete industrial chain are the direction that the park has been exploring. Lin Xiaoming, director of the Organization Department of Suzhou Industrial Park Management Committee, said that he hopes that the cooperation between Airbus and Nano Institute will provide a new model for the cooperation between international enterprises and the park, and promote the development of “technical bonsai” as “industry landscape”.

The signing of this cooperation marks the official launch of Airbus's nano-development program in China. The joint lab aims to improve the fuselage and wings through nanomaterials, and will also provide "intelligent services" for the healthy operation of aircraft. Lu Weibang, a researcher at the Advanced Materials Department of Suzhou Nano Institute, said that the laboratory will set up a research and development team of more than 20 people to modify the carbon fiber in the Airbus A350 with nano-materials. In addition, "inductive components" will be added to the nano-films used. Intelligent sensing system provides data reference for maintenance and operation of the fuselage.
