The reporter learned from the China Petroleum & Chemical Corporation(600028) Information Office on the 11th that recently, China Petroleum & Chemical Corporation(600028) carbon fiber independently developed and produced has been successfully applied to the “bay area blue” high-speed train of Guangzhou metro line 18. The operation data shows that the performance of the train hood made of carbon fiber composite material fully meets the operation conditions. Compared with the aluminum alloy material of the same module, it can reduce the weight by 35% – 40%, and effectively help the train reduce weight and speed
It is reported that China Petroleum & Chemical Corporation(600028) also put on a carbon fiber “coat” for the “flying” of the Beijing 2022 Winter Olympic torch, which is the first time in the world to make the Olympic torch shell with carbon fiber composite materials, which solves the technical problem that the torch needs to be resistant to high temperature when burning hydrogen fuel, making it “light, solid and beautiful”, It can be used normally in hydrogen combustion environment higher than 800 ℃. Compared with the cold metal torch shell, “flying” makes the torchbearers feel warm and contributes to the “Green Olympics”
Carbon fiber is a new high-strength fiber material with carbon content of more than 95%. It has excellent mechanical properties. Its quality is one quarter of that of steel, but its strength is seven to nine times that of steel. It also has corrosion resistance. It is known as the “king of new materials” and “black gold”. It can be widely used in aircraft parts, rail transit raw materials, body manufacturing, etc, It has broad application prospects in all walks of life.
It is understood that Guangzhou metro line 18 is known as the fastest Metro in the Greater Bay area of Guangdong, Hong Kong and Macao, with a maximum speed of 160 kilometers per hour. The “bay area blue” train, which is responsible for the operation task, is the first metro train in China with light and high-strength carbon fiber composite material for its head cover. Since 2019, China Petroleum & Chemical Corporation(600028) and Crrc Corporation Limited(601766) have carried out collaborative innovation, overcome the key core technologies of large-scale application of carbon fiber composites in the field of rail transit, established a complete technology R & D system, formed a world-leading “one-stop” lightweight technology solution, and finally realized the successful application of carbon fiber composites on the “bay area blue” train.
In the next step, China Petroleum & Chemical Corporation(600028) carbon fiber will also be applied to the train of Guangzhou metro line 22. In addition, the R & D teams of China Petroleum & Chemical Corporation(600028) and Crrc Corporation Limited(601766) are also actively carrying out research on carbon fiber composite technology applied to higher performance models such as 400 km / h high-speed trains and maglev trains, opening up a broader field for the development of China’s carbon fiber and composite industry chain.
Carbon fiber technology has strict technical barriers, China Petroleum & Chemical Corporation(600028) Sinopec Shanghai Petrochemical Company Limited(600688) is an early enterprise in China to develop carbon fiber and carry out industrial production. As early as 2012, the company adopted the self-developed complete set of carbon fiber technology to produce 12K small tow carbon fiber. In 2018, the company successfully trial produced 48K large tow carbon fiber with international advanced level. It is reported that China Petroleum & Chemical Corporation(600028) has carbon fiber technology developed with independent intellectual property rights. At present, the patent application ranks first in China and third in the world.
