How strong is the infrastructure maniac? Nowadays, China directly uses bamboo to build high-speed rail, directly subverting the imagination of the world! Because the high-speed rail built in this way is as hard as concrete, or even harder than it, is it true? After the difficulty was exposed, countries have expressed disbelief, and foreign experts have also come to examine it, and it was found that China used a bamboo fiber weaving composite material technology, which can not only create high-speed rail carriages, but also achieve weight reduction and environmental protection and other advantages, for which the United States can only be red-eyed.

At present, the construction of China's high-speed rail mainly relies on metal materials such as aluminum and carbon fiber, which will not only consume a lot of resources every year, but also cause damage to the environment, especially the production of aluminum usually requires the use of electrolysis, which will consume a lot of electrical energy, and now the Chinese engineering team through a large number of research and development, finally created an advanced fiber that can be used for high-speed rail construction: bamboo winding composite materials.
The reason for choosing bamboo is because it has the advantages of toughness and high elasticity, and using these characteristics, Chinese scientists use it as a substrate, while using resin as a binder, and the final product is very light in weight, and at the same time has a strength comparable to c30 concrete, and the traditional carbon fiber and other materials are almost the same, is an excellent raw material for manufacturing high-speed rail carriages and internal facilities, so what advantages can it bring?

First of all, because the bamboo itself is a low-carbon environmentally friendly green material, so the carriage made of it, after being decommissioned and scrapped, can be treated by a more environmentally friendly method, will not produce a large amount of waste harmful to the environment, and because the production speed of this plant is extremely fast, so its recyclability is far more than aluminum and steel and other difficult materials to manufacture, bamboo This plant can reach 150 million tons of domestic annual output, but only 1/3 of it can be used, and a large part of the rest has to be wasted. Therefore, if it can be applied to the production of high-speed rail, on the one hand, idle materials can be used, On the other hand, it can reduce carbon dioxide emissions by 350 million tons, compared with 25 million tons of bamboo can produce 10 million tons of this material, and the bamboo itself that has not yet been cut is still photosynthesis, absorbing carbon dioxide and releasing oxygen at the same time, which means that it actually saves more carbon emissions, to produce the same weight of steel pipes, it needs 45,000 tons of crude steel, and in the process also needs to use 22.8 million tons of coal for forging work, and the emission of carbon dioxide and other toxic gases can be imagined.
The second advantage of bamboo composite materials is that even if this material is not completely used for vehicle manufacturing, compared with traditional materials, the weight is still reduced by 1/3, if the entire use of this product to make a whole train of high-speed rail, then it will be 1/4 lighter than the original, and energy consumption will be reduced by 30%, for China, which is still more dependent on thermal power generation, saving these electric energy can not only reduce the expenditure of funds, but also reduce the coal use of power stations. Make outstanding contributions to the cause of environmental protection in the country and even the world.

At present, the experiments related to this material are still in full swing, and after passing the test, in the future life, we may not only be able to see this kind of it on the high-speed rail, but also the cars and even houses made of it, which is the great achievement brought about by China's advanced scientific research capabilities.
