At 17:38 on June 11, 2013, the Shenzhou-10 spacecraft was launched and carried out the manned space rendezvous and docking mission. Research institutes and textile companies such as the Composite Materials Research Institute of Tianjin University of Technology, Tongniu Group, and Jihua Group have respectively undertaken relevant projects to help China’s aerospace industry.
According to reports, the composite materials of key components of “Shenzhou 10” adopt high-tech special textile reinforcement materials developed by the Composite Materials Research Institute of Tianjin University of Technology, which represents the application level of China’s advanced composite materials. According to Professor Chen Li, director of the Composite Materials Research Institute of Tianjin University of Technology, in order to adapt to the harsh flight environment and reduce the structural weight, high-performance composite materials were selected for key parts of the Shenzhou-10 spacecraft. The special textile reinforcement materials developed by Tianjin Polytechnic University have become the preferred reinforced skeleton materials for key components of composite materials. They have excellent properties of light weight, high strength, and ablation resistance. They also reduce the structural weight and significantly improve the performance of the spacecraft.
Special textile reinforcement materials have a high degree of freedom in design. By changing the internal structure of the material, the mechanical and physical properties of the material can be “designed” within a wide range to meet the requirements for use in special environments. At present, special textile reinforcement materials are considered to be the most effective method to improve the strength, ablation resistance, thermal shock resistance and creep resistance of composite materials. They are also a key technology to realize the integrated design and manufacturing of aircraft structures, so they have become a new Core technologies and key development areas for the development of first-generation aircraft.
The Institute of Composite Materials of Tianjin University of Technology has established the only advanced textile composite materials research and development platform in China that integrates material design, multi-directional weaving, liquid molding, and material performance characterization, and has undertaken the completion of supporting research and development tasks for a number of national key projects. , the research results have reached the international advanced level and have been successfully used in high-tech fields such as my country’s lunar exploration satellites, spacecrafts, launch vehicles, long-range missiles and new fighter aircraft.
As the largest integrated supplier of military supplies in the country, the “Jihua” element continues to shine in the “Shenzhou” flight process. In this Shenzhou-10 launch and docking mission, Jihua Group is mainly responsible for the development and production of astronaut expedition boots and rendezvous and docking boots. It is understood that the two types of shoes are manufactured by the Shanghai Special Shoes Branch of Jihua. The company has undertaken the development and production of astronaut series shoes and boots in previous manned space missions from Shenzhou 5 to Shenzhou 9.
According to Wu Junjie, the chief designer of Jihua Group and the project leader of this manned space shoe mission, for the research and development of manned space shoes series, the scientific research team of Shanghai Special Footwear Branch followed the actual flight generation and improved generation , the concept of designing one generation and storing one generation puts the scientific research work on aerospace shoes and boots on the basis of “actual flight, improvement and advancement”. Compared with the shoes and boots developed in previous launches, the “Shenshi” series of shoes developed this time adopt the “physical measurement + paste mold shaping” value method to make the last body design “one-to-one” infinitely close to the astronauts’ feet. According to the requirements of technical and tactical indicators and the special needs of aerospace, scientific researchers have made new adjustments to the internal shape and materials of shoes and boots on the premise of standardized appearance to achieve higher anti-static performance, stronger comfort, and better body feel. , the wearing effect during exercise tends to be more convenient and fit. It is understood that the “Shenzhou-10” astronauts expressed great satisfaction after trying out the suit.
The emergency production task of “Shenjiu Search and Rescue Suit” previously undertaken by Jihua 3502 Company has been highly recognized by the aerospace staff of various bases. Facing this year’s Shenzhou-10 launch mission, Jihua 3502 Company, on the basis of continuing to produce search and rescue suits, has further obtained the development work of a series of functional clothing such as anti-static and anti-microwave clothing for ground staff at the launch base. .
The relevant person in charge of the company’s professional clothing research institute said that the various functional clothing for ground staff produced this time have made greater breakthroughs in design ideas and concepts. Anti-static and anti-microwave gowns are made of anti-static and anti-radiation materials respectively; the matching clothing of search and rescue work clothes is very eye-catching, and various accessories must also be anti-static and anti-radiation; the design pays more attention to humanization, which is both beautiful and practical, and in line with the requirements The characteristics of base work play a role in human body protection. The collars of the radiation-proof clothing and coats of each unit adopt a closed collar design to minimize the exposure range; in addition, the requirements for details are more stringent, such as adding walkie-talkie loops and walkie-talkie bags to the chest of search and rescue work clothes. A chest logo and reflective markings are added to the front chest to distinguish aerial and underground work clothes in green and blue.
It is understood that the search and rescue work equipment contracted this time is functionally divided into air units and ground units, and is divided into search and rescue team members and search and rescue command working groups in terms of type. There are 5 styles for men and women, and 440 sets of production tasks; anti-static, anti-static, There are 4 styles of microwave coats for men and women, with a total of 10,260 production tasks. The company has completed the orderly distribution of clothing to 19 units in 16 provinces and cities across the country on May 12, and has sent clothing from three units in Aerospace City directly to Beijing by special vehicles.
The “Shenzhou 10” astronauts’ underwear is tailor-made for Tongniu Group. Copper Bull��After the astronauts of “Shenzhou 5”, “Shenzhou 6” and “Shenzhou 7” successfully flew into space, Beijing Tongniu Group, as a group member of the China Association for Quality Inspection, successfully developed aerospace equipment for the male and female “Shenzhou 9” astronauts. Physiological signal test vest, astronaut thermal underwear, aerospace underwear, aerospace gloves, aerospace bags, etc. With the smooth launch of “Shenzhou 10”, “Tongniu underwear, aerospace quality” has once again become the best interpretation of the Tongniu brand.
