Dai Dailiang said that the main reasons for the failure of some aerospace projects in developed countries are not in the control technology but in the application of materials. Many of the new materials used by our country for high-end spacecraft like the "Shenzhou VI" have reached the international advanced level, ensuring the success of our country's many space launch missions. But it is also necessary to continuously carry out technological innovations in accordance with the needs of aerospace technology development. New materials such as special aerospace coatings, rubber seals, high-grade lubricants, and integrated chips can only rely on our own innovation for R&D and production, and their technologies and products are impossible. Imported from abroad. Therefore, in the past few years, a considerable portion of the country’s huge investment in the aerospace field has been invested in the production and research and development of key high-tech materials.
Dai Dailiang believes that in order to support the technological advancement and development of new aerospace materials, institutional innovation is also needed. Therefore, at this NPC session, he will make proposals to accelerate the military-civilian unity of aerospace material production. According to Dai Zhengliang, in developed countries such as the United States, 80% of the production of new aerospace materials is a combination of military and civilian forces. At present, the military-civilian integration of new aerospace materials in China is still not high. The state should promote this work during the “Eleventh Five-Year Plan†period. This can save the country's investment on the one hand, and on the other hand it can also promote the degree of marketization and the improvement of the technological level of production enterprises. At the same time, the high-tech nature of aerospace materials can also be used to drive the development of related industries, maximize the value of national investment, and increase the nation’s overall national strength.
According to the reporter's understanding, on the "Shenzhou VI" manned spacecraft that successfully completed its space mission last year, 90% of the total mass was chemical new materials. In the "Eleventh Five-Year Plan Outline (Draft) of the People's Republic of China for National Economic and Social Development" discussed at this people's assembly, the industrial projects that require major development include high-performance new materials that are urgently needed in the aerospace field. Industrialization demonstration project.
The 10th National People's Congress Standing Committee member and famous space expert Dai Zhenliang proposed that the 21st century frontier technology is supported by new materials.
On March 5, the 10th National People's Congress Standing Committee member and famous space expert Dai Jinliang said in an interview with reporters at the opening of the National People's Congress that the development of space technology as a key frontier technology in the 21st century must be supported by new materials. The successful launch of China’s “Shenzhou VI†manned spacecraft proved that if there is no support for new aerospace materials such as rocket propellant, aerospace special coating, and advanced composite materials, the development of space technology will be difficult to make progress, and it will be even less likely to become a space power.
