Industrial use

As a new star in the textile industry, we take advantage of this opportunity to popularize technology and application in the civilian field.

Big to God nine, the increasing structure of the spaceship and the glove of astronauts all contain the frontier technology of textile science and technology, reflecting the current level of the development of industrial textiles.

In this plan, we enumerated some industrial textiles involved in manned rendezvous and docking tasks, and interviewed through research and development parties in order to understand the technology and stories behind the products.

The textile enterprises, institutions and research institutes that participated in the nine ascension task of God have been closely following the project for ten years. Some have worked overtime to ensure their tasks, and some have conscientiously strengthened teamwork.

Their products have been tested in the docking task, contributing to the development of the space industry, and laying a solid foundation for the technical research of the products.

The process and mode of their R & D have been affirmed in the results of qualified products; the efficient pformation mode of production, teaching and research and independent research and development have ensured the advantage of product upgrading and coherence, and have been displayed perfectly in this task.

Production, teaching, research, coordination, and coordination of high-quality products: semi steel solar panels

Tiangong-1 only has a pair of solar panels at the rear, with a new semi steel structure. The bracket of the fixed battery is similar to badminton racket, consisting of metal frame and nylon net.

Glass fiber woven semi - rigid solar panels are characterized by light weight and high energy efficiency.

Compared with traditional all steel solar panels, the power generation of semi steel solar panels increased by 30% and the weight by 40%.

The semi steel solar panels, which were applied in Tiangong-1 space laboratory, were jointly developed by Donghua University, Shanghai Aerospace 805 Research Institute, Nanjing glass fiber research institute and Changzhou Wujin five ocean Textile Machinery Co., Ltd.

Among them, Nanjing glass fiber research institute is responsible for providing glass fiber, and Changzhou Wujin five Textile Machinery Co., Ltd. is responsible for providing machines. Donghua University is responsible for design and production, while Shanghai Aerospace 805 Research Institute is responsible for overall planning and coordination.

According to Professor Chen Nanliang of Donghua University, the research and development of the research and development of the semi steel solar panel project of Donghua University has 5~6 people. The research and development of the project began in 2004, completed at the end of 2006, and was applied last year.

The research and development fund of Donghua University is about about one million yuan.

When asked about the promotion time of the technology project, Professor Chen said that the possibility of applying the project to civilian use is not large, mainly because the price is too expensive.

Breakthrough technical difficulties: Aerospace gloves

Space glove has high technology content, it is pressure resistant, tensile, high temperature and low temperature, and has high air tightness.

Gloves on spacesuit have a hermetically sealed airtight coat.

The inner surface of the glove is attached to the fabric except for the thumb and the other fingers. The part of the glove is not to stick the fabric to make the astronauts feel sensitive enough.

The glove of the outer part of the glove is embedded with a limited expansion structure to prevent the glove from expanding too much due to internal pressure.

The Institute of rubber industry of Tianjin has been successfully applied to the astronaut's hand for the "nine hands" made by the astronaut of the rubber industry.

According to Wang Wei, Minister of the Ministry of science and technology, there are 10 people in charge of R & D gloves. They have been involved in the research and development of Shenwu, Shenzhou VI, Shen seven, Shen eight and Shensi nine, and have constantly broken through technical difficulties.

The state will invest part of its funds in the research and development of products, and the Institute will raise some of its own funds.

After successful R & D, enterprises enjoy ownership of the industry, and the state will contribute to buy back products.

The weight of the product is accurate to 0.1 grams / square meter: special glass fiber cloth.

The special glass fiber cloth ultra-fine glass yarn is made of "textile". Its properties include high temperature resistance, high insulation, good corrosion resistance, less moisture absorption, strong pulling resistance and good heat preservation performance. It is a rocket's genuine "thermal underwear".

Jiangsu Jiuding new material Limited by Share Ltd is a company specializing in special products.

The production enterprise mainly produces and sells glass fiber yarn, fabric and products, FRP products, building and decoration reinforcement materials, other industrial fibers, fabrics and products. It is China's glass fiber deep processing product base, and its products are more than 60% exported.

Since the 80s of last century, Jiuding new material has become the supplier of glass fiber cloth designated by the Ministry of Astronautics.

The Shenzhou nine launch vehicle has used the aerospace special glass fiber cloth. This cloth is no more than the general cotton gauze. The yarn it uses is actually a glass fiber with a diameter of only 0.66 millimeters. The woven glass fiber cloth has high strength and good thermal insulation performance. It is mainly used in the periphery of the liquid hydrogen oxygen tank of the launch vehicle, and is the rocket's genuine "thermal underwear".

The weaving of glass cloth needs excellent technology.

In addition to the requirement of weighing 0.1 grams per square metre on the weight of the product, the requirements for product quality can be described with severity.

From 80s's "Shenyi" to today's "God nine", Jiuding new material has been undertaking the task of providing aluminum special glass fiber cloth for launch vehicles and spaceships.

In the past 20 years, Jiuding new material has witnessed the development course of China's space industry from a small cloth.

Ending the history of long dependence on imports: astronauts series boots and search suits

This series

According to the requirements of the corresponding tasks, there are various kinds of boots, cabin protective boots and cabin boots.

The search and rescue clothing is designed and manufactured according to the actual needs of the return system of the nine spacecraft in the landing field and the actual search and rescue environment of land and air personnel.

During the manned space rendezvous mission of the nine spacecraft, the Shanghai special shoe and shoe branch of the China Group has provided the high-tech development of astronauts with high antistatic, anti radiation and puncturing techniques.

Since 2000, the Shanghai special shoe branch has established a cooperative relationship with the astronaut center, undertaking the R & D design task of the astronaut leather boots series products.

According to the changing regularity of astronauts' operational ability, the company's scientific research personnel have successively developed a lightweight, comfortable, moisture absorption, thermal insulation and constant temperature technology boots, dustproof protective boots with dust-proof, anti pollution, radiation protection, anti-static and anti piercing functions; and have the technology of cosmic radiation protection, extreme humidity difference protection, space junk impact protection, electrostatic protection, heat and cold exchange balance, and human space counterpoint technology.

The performance of the spacecraft at various stages of test, launch, operation and recovery is stable, conforming to the design requirements, providing reliable guarantee for the flight operations of Shenwu, Shenzhou VI and Shenzhou seven astronauts, ending the history of relying on imports in the past, and filling the gaps in China's space equipment.

In late March this year, the 3502 Chinese companies received the notice of trial production of "Shen nine search and rescue service" of the PLA General Armament Department.

The leaders of the 3502 China Company attached great importance to it and set up a project team at the first time.
