High-precision special textiles help “Shenshi” fly into the sky

HC Plastics Network News: At 17:38 on June 11, it was another exciting moment for the Chinese. my country’s fifth manned spacecraft, Shenzhou 10, was launched from the Jiuquan Satellite Launch Center. It is planned to implement a manned space rendezvous and docking mission in the next 15 days.

The textile figure on the “Shenshi”

Recently, the lives of three astronauts in space, Nie Haisheng, Zhang Xiaoguang, and Wang Yaping, have become the focus of global attention. In various TV scenes that frequently appear, we see that astronauts can bathe and sleep in the spacecraft, and even eat rice dumplings during the Dragon Boat Festival. Behind these warm scenes, thanks to the dedicated efforts of scientific and technological personnel, soft, comfortable and close-fitting space-specific underwear is an important element to ensure the quality of life of astronauts. The underwear worn by the three astronauts of the Shenzhou-10 spacecraft during this flight were all customized by Tongniu Group. With the successful flight of the Shenzhou 5, Shenzhou 6 and Shenzhou 7 astronauts, Tongniu Group has further accumulated technology in the aerospace field. It is reported that Tongniu Group has successfully developed aerospace physiological signal test vests, astronaut thermal underwear, aerospace underwear, aerospace gloves, aerospace bags and other clothing items for the three astronauts of Shenzhou 9. This time, the Shenzhou 10 mission went smoothly. Lifting off also once again interpreted the inner meaning of the Tongniu brand “Tongniu underwear, aerospace quality”.

Shenzhou 10, carrying the Chinese people’s “flying dream”

What makes textiles shine on Shenzhou 10 are related projects undertaken by universities, scientific research institutes, textile companies such as Tianjin University of Technology’s Institute of Composite Materials and Jihua Group. Through their continuous efforts to overcome difficulties, they finally succeeded in sending their textile technology into space.

It was learned that the composite material of the key component of Shenzhou 10 is special textile reinforcement material. This extremely high-tech material was developed by the Composite Materials Research Institute of Tianjin University of Technology. Chen Li, director of the Composite Materials Research Institute of Tianjin Polytechnic University, told reporters that after Shenzhou 10 takes flight, it will need to face a harsh flight environment. Therefore, the reinforced skeleton materials in key parts are required to have excellent properties of light weight, high strength, and ablation resistance. . At the same time, this manned space mission also put forward requirements for reducing the structural weight of Shenzhou 10. In this case, the special textile reinforcement materials developed by the Composite Materials Research Institute of Tianjin University of Technology became the key to Shenzhou 10. Final choice.

The spacesuit worn by Shenzhou 5 astronaut Yang Liwei; the parachute used to slow down the Shenzhou 6 spacecraft after returning to the atmosphere, are all made of high-performance textile materials.

If these two examples are not enough to illustrate the role of textiles in the aerospace field, then Chen Nanliang, director of the Engineering Research Center for Industrial Textiles of the Ministry of Education of Donghua University, and his research team used glass fibers to weave “semi-rigid glass”. “Fibre Grid” is an indispensable equipment to ensure that Tiangong-1 can fly in space. With it, there is the “Tiangong” China Space Kiss.

Turning our attention to Shenzhou 9, if we draw a list of textiles for Shenzhou 9, cutting-edge products such as aerospace gloves, astronaut series search and rescue suits and shoes, and special fiberglass cloth are all on the list.

It is understood that the space gloves used by the three astronauts on Shenzhou 9 were tailor-made for them by the Tianjin Rubber Industry Research Institute. This kind of in-cabin finger pressure glove has a load-bearing airtight jacket. The entire inner surface of the glove, except for the thumb and the tips of other fingers, is adhered with fabric. The non-adhesive areas can be used by aerospace personnel. Keep your sense of touch sensitive.
