In October 9th, Chang'e two was successfully launched in third months and entered the scheduled orbit.

After the successful launch of the Chang'e two satellite and launch vehicle in October 1st, the satellite entered the lunar orbit, which marked the great success of the lunar exploration project in China.

This important project also condenses the labor and wisdom of textile workers.

In the interview, the reporter learned that Chang'e two is the backup star of Chang'e 1, and is also the guiding star for the two phase of the lunar exploration project.

In the Chinese lunar exploration project,

textile industry

The important part of the industry has made a unique contribution to the textile industry.

Professor Li Jialu, director of the Composite Materials Research Institute of Tianjin University of Technology, who is responsible for the research and development of satellite engine supports and hatches, told reporters that the engine bracket of Chang'e two satellite was made of high-performance fiber composites, and used resin solidification and a series of complex technologies.

Because of its good neutrality in the application of Shenzhou 7 spacecraft, this support has become the first choice for the lunar exploration project.

Li Jialu said that the new lunar landing project and Shenzhou 8 manned spaceflight project are inseparable from industrial textiles.

For example, the hood of the engine adopts

Textile fiber

Composite materials, with high technology content, represent the advanced mechanical manufacturing technology and the application level of high performance composite fibers in China.

In recent years, industrial composite fibers and products have been widely used in aerospace engineering. The space shuttle developed by the US space agency in the 70s of the last century is also known as "memory cotton". It is a support and protective pad designed for astronauts to carry out space travel, and it can relieve the tremendous gravity pressure of astronauts during takeoff and flight.

This material has the characteristics of shock absorption, decompression and slow rebound. It can automatically adjust the shape according to the curve and temperature of the body, thereby resolving the pressure of the body's pressing points.

With the development of this technology

innovate

Memory foam has been widely used in home textiles, automobiles and other fields.

The "diapers" produced by spunbonded nonwoven or spunbonded nonwoven fabrics solve the problems encountered by astronauts in spacewalking for a long time.

The liquid cooled clothing is the space technology from the Apollo space program. It can protect the astronauts from being affected by temperature changes during the cabin activities and ensure the safety of astronauts.

At present, more and more high-temperature workers begin to wear liquid cooling clothing, such as racing drivers, nuclear reactor technicians, shipbuilders, etc.

In addition, liquid cooled clothing is also applied to physical therapy and sports rehabilitation equipment. It alleviated pain for some patients with special diseases and played an increasingly important role in people's work and life.

Parachute recovery system was originally used for space capsule recycling, and now it is designed by the relevant American agencies to prevent air crash.

Its material is high strength nylon 66, and the rope is high strength polyethylene or nylon material.

The parachute system can be ejected by manual operation and can be opened quickly within one second.

When the aircraft is out of control, the captain can open a parachute to make a safe landing of the aircraft. The system is expected to be used for the manufacture of a large passenger plane.
