How can domestic textile materials and carbon fiber materials get on the high-speed rail

forget the thrilling moment when the Shanghai Hangzhou high-speed rail started -

9:01, the first high-speed rail train from Shanghai to Hangzhou started. A helicopter took off from Jiashan South Railway Station and hovered in the air waiting for the arrival of the Shanghai Hangzhou high-speed train

9:15, the Shanghai Hangzhou high-speed rail train passes through Jiashan south. At this moment, the helicopter hovering over Jiashan South flew to Hangzhou at full speed. High speed rail trains and helicopters go hand in hand

9:16, the Shanghai Hangzhou high-speed train quickly surpassed the helicopter in the air and left the helicopter behind

At 9:39, the first high-speed train from Shanghai to Hangzhou arrived at Hangzhou city station

10:05, the helicopter arrived over Hangzhou city station. In this contest between Shanghai Hangzhou high-speed railway and helicopter, Shanghai Hangzhou high-speed railway flew close to the ground, and its driving speed exceeded that of helicopter...

Shanghai Hangzhou high-speed railway once again let the world see "China's speed"! Just a cup of tea, you will be from the bustling fashion city to a quiet paradise on earth

high speed rail not only concentrates modern rail transit technology, machinery manufacturing technology and electric control technology, but also integrates high-tech fiber technology and new materials directly related to textile. It is the use of high-tech fiber materials such as carbon fiber that makes the high-speed rail as light as a swallow without losing strength

carbon fiber and other new fiber materials make the high-speed train abandon the traditional steel structure body, realize ultra lightweight, greatly reduce energy consumption and significantly increase the speed per hour. It is worth mentioning that the carbon fiber materials used in the car body can also be recycled

the impact resistance of carbon fiber material is much stronger than that of steel. Especially, the mechanical strength and impact resistance of the steering wheel made of carbon fiber are increased by more than 35% and 20% respectively compared with ordinary materials. Theoretically, the strength of the whole vehicle is at least 20%~30% stronger than that of the body made of ordinary materials. Under the arms of composite materials, the safety of high-speed rail is self-evident

the application of new carbon fiber materials will not only promote the low-carbon operation of high-speed trains, but also bring about the green production of vehicle materials and lead the reform of rail transit industry. Germany and Japan are already planning to realize the industrialization of carbon fiber vehicles in the next twoorthree years. At present, new carbon fiber materials have been widely used in aerospace and other high-tech fields in China. New carbon fiber materials have been widely used in Shenzhou spaceship, Chang'e rocket, large aircraft manufacturing, etc

after finishing the car body, take out the gauge rod gasket and talk about the interior. The interior soft decoration of Shanghai Hangzhou high-speed railway adopts domestic textiles, and all of them meet the international environmental protection and flame retardant standards. In a recent interview, the author had the honor to meet the person in charge of Hangzhou WANGU Textile Co., Ltd., a manufacturer that provides interior materials for high-speed rail. From him, the author learned about the special requirements of high-speed rail interior textiles

according to his introduction, the fibers used in high-speed rail interior textiles must have flame retardancy, environmental protection and other functions, and the relevant physical indicators must meet and provide basic support for the realization of international standards as a manufacturing power in the middle of this century. The flame-retardant fiber used in high-speed rail is completely different from the traditional flame-retardant fiber. The requirements of flame-retardant fiber in motion and static state during 1015 are completely different. In particular, the high-speed operation of high-speed rail and large aircraft puts forward unconventional requirements for the indicators of flame retardant fibers. When the speed of high-speed rail reaches 250 km/h, the performance index of flame retardant fiber is much higher than the requirement of 200 km/h

at present, there is no corresponding national standard for such high-performance flame-retardant fibers in China. The flame-retardant fibers used in the interior of high-speed rail refer to the relevant standards of Boeing and Deutsche Bahn. There are only a few domestic enterprises that can produce this kind of high-standard flame retardant fiber. The research and development of high-performance flame retardant fiber is a great challenge to the current production capacity and testing level of China's mold micro processing technology, because this kind of fiber must have strict and scientific management and control means in the processing process, on-site control, product indicators and other links

acknowledging the gap does not mean being willing to lag behind. Although there is still a big gap between China and the United States, Germany, Japan and other developed countries in the research and development of high-tech fibers and related materials such as carbon fiber, glass fiber and high-performance flame retardant fiber; Although we still have some shortcomings in the field of high-tech fibers, such as lagging standards, we are trying to catch up and narrow the gap. Especially when the developed countries block the key technologies in this field, the Chinese people have realized the localization of a variety of high-tech fibers and materials through self-reliance with a spirit of not admitting defeat. With the high attention of the state and the joint efforts of industry enterprises, The localization level of a number of high-tech fibers such as carbon fiber has been continuously improved

why talk more? Domestic high-tech fibers and materials have now boarded the spaceship, large aircraft and high-speed rail... This is not the pride of the Chinese people and textile people
