Nowadays, China’s high-speed rail strength is so strong that the world dare not to look down on it, and can even win the market of other countries. China is still exploring new high-speed rail technology. Recently, another unique technology of China has become popular all over the world. After adopting this technology, China can use bamboo to build high-speed rail instead of steel, which has aroused widespread concern. Can China really use bamboo to build high-speed rail? Does it make it stronger than concrete? Some experts are proud to say that this is the new plant composite material technology developed by China. If China's high-speed rail can be constructed using this technology, the energy consumption of the high-speed rail system can be reduced by nearly 20% each year, saving tens of billions of electricity bills. Expenditures greatly promote the development of China's high-speed rail industry.
This technology is called plant-based composite material technology, which means that bamboo can be used instead of other materials to make composite materials. The high-speed rail currently used in China uses a large number of composite materials. This material uses higher-strength fibers, such as carbon fiber or glass fiber. Mixed with plastics with lower strength but good toughness, it is a material made like reinforced concrete. Compared with steel, they have superior performance and lighter weight. Therefore, they have been widely used. This time, the Chinese research and development The plant-based composite material is to replace the carbon fiber or glass fiber with a composite material made of wood fiber extracted from bamboo, which has more powerful performance.
Because the strength of bamboo fiber is not as good as that of carbon fiber, the strength of this plant-based composite material is actually not as good as that of traditional composite materials, but its biggest advantage is that it is lighter. The strength of China’s plant-based composite materials is also sufficient to meet the requirements of manufacturing high-speed rail cars. Because of the lighter weight, although the use of this material to make high-speed rail consumes more materials, the overall high-speed rail car manufactured is 30% lighter than the high-speed rail car made of traditional composite materials. If an entire high-speed rail train uses this With a new technology, its overall weight can be reduced by 20%, energy consumption can be reduced by more than 20%, and operating efficiency can be greatly improved.
At present, the high-speed railways developed in China are driven by electricity. If this technology is used to manufacture new high-speed rail trains, the high-speed rail system in China can save tens of billions or even tens of billions of dollars in electricity expenses every year, which is not only conducive to reducing The fares of high-speed rail will reduce the economic pressure of people traveling by high-speed rail. At the same time, it will also help China's environmental protection and enable China to realize its centennial plan of carbon neutrality at an early date.
In addition to manufacturing high-speed trains, this new material and technology can also be used in other areas, such as manufacturing new aircraft, automobiles, and pipelines, etc. If this technology can be widely used in all walks of life, its environmental benefits It will be even higher, because the industries producing carbon fiber and glass fiber are typical high-energy-consuming enterprises and need to consume a lot of energy, while the production of bamboo requires only enough sunlight, water and soil, and produces almost no pollution, but it also helps to absorb carbon dioxide.
Therefore, once this technology is popularized on a large scale, it is expected to suppress the demand for carbon fiber and glass fiber, reduce the energy expenditure and pollutant emissions for the production of these materials, and thus play a greater environmental protection effect. It is also hoped that this technology can be applied as soon as possible. High-speed rail and other industries.
