Tiangong Weaving Technology: Tianjin University Of Technology Textile First-Class Discipline Helps Astronauts Triumph

Autumn thick as wine, flying into the sky, spring flowers bloom triumphantly back. On April 16, 2022, with the world's attention, the Shenzhou 13 manned spacecraft's return capsule landed in the predetermined area of the Dongfeng landing site. Astronauts ZhaiZhiGang, Wang Yaping and ye Guangfu all safely and smoothly left the warehouse. The Shenzhou 13 manned mission was a complete success.

In this mission, the Shenzhou 13 has contributed a lot to the mission. The team of Professor Chen Li from the textile future technology research center of Tianjin University of technology uses a new generation of "Tiangong weaving technology" to guard the astronauts' way home.

In order to ensure the successful return of astronauts, Professor Chen Li led the team to break through a number of key technologies, and developed high-temperature multi-directional braided reinforcement materials for shenzhou-13 capsule. When the Shenzhou 13 manned spacecraft returns, it rubs violently with the atmosphere at the speed of several kilometers per second and ignites a high-temperature flame of more than 2000 degrees. This reinforcing material can provide excellent structural reinforcement and performance reinforcement for the key components of the re-entry capsule, and accurately meet the requirements of the protective structure composite material for the key components of the re-entry capsule for "high temperature ablation resistance, firmness and impact resistance", Make new contributions to the safe landing of astronauts.

The team of composite Research Institute led by Professor Chen Li has long been engaged in the basic research and technology development of multidimensional braided materials and their composites in the field of aerospace, relying on the national and local joint engineering research center of "high performance fiber and textile composite preparation technology", the Key Laboratory of the Ministry of education of the Ministry of education, and the Ministry of education The engineering research center of the Ministry of education and the Key Laboratory of textile industry have built a rapid response research platform for advanced textile composite materials integrating material design, multi-dimensional weaving, liquid forming and performance characterization. It has obvious characteristics and advantages in the three-dimensional weaving of complex shaped composite components, and its scientific and technological achievements have reached the international advanced level, and won two second-class national science and technology awards Five provincial and ministerial science and technology awards were awarded, and the multi-directional braided reinforcement materials were successfully applied to the return module of "Shenzhou 7" to "Shenzhou 13".

The flying dream will never lose weight, and the tension of science dream is infinite. Tianjin University of technology textile first-class discipline will always be guided by the "double first-class" construction, facing the major strategic needs of the country, continuously strengthening scientific research and tackling key problems, and continuously contributing "Tiangong power" and "Tiangong program" to China's aerospace industry!
