Everybody knows
The Beijing Winter Olympic Torch "Flying" was developed and mass-produced by Sinopec Shanghai Petrochemical
The flare shell is made of carbon fiber composite material developed by Shanghai Petrochemical
Recently, the carbon fiber independently developed and produced by Sinopec Shanghai Petrochemical was successfully applied to the "Bay Area Blue" high-speed train of Guangzhou Metro Line 18
The operating data shows that the performance of the train head cover using carbon fiber composite material is fully in line with the operating conditions, and the weight reduction of the same module can be reduced by up to 35%-40% compared with the aluminum alloy material of the same module, effectively helping the train to reduce weight and speed
Carbon fiber is a high-strength new fiber material with a carbon content of more than 95% Excellent mechanical properties Excellent quality is a quarter of the strength of steel but seven to nine times that of steel and also has corrosion resistance characteristics known as the "king of new materials" also known as "black gold"
Can be widely used in aircraft components, rail transportation raw materials, body manufacturing, etc. in various industries have a wide range of application prospects
It is understood that Guangzhou Metro Line 18 is known as the fastest metro in the Guangdong-Hong Kong-Macao Greater Bay Area with a maximum speed of up to 160 kilometers per hour to operate the "Bay Area Blue" train is the first subway train in China with a lightweight high-strength carbon fiber composite hood
Since 2019, Sinopec and CRRC have carried out collaborative innovation to overcome the key core technologies of carbon fiber composites in the field of rail transit, establishing a complete technology research and development system to form the world's leading "one-stop" lightweight technology solution and finally realizing the successful application of carbon fiber composites on the "Bay Area Blue" train
In the next step, Sinopec carbon fiber will also be applied on the train of Guangzhou Metro Line 22
In addition, the R&D teams of Sinopec and CRRC are also actively carrying out carbon fiber composite material technology research applied to higher performance grade models such as 400 km per hour high-speed trains and maglev trains to open up a broader field for the development of the industrial chain of carbon fiber and its composite materials in the mainland
Sinopec's carbon fiber "coat" for the Beijing 2022 Winter Olympic Torch is the world's first realization of carbon fiber composite materials to make the Olympic torch shell to solve the technical problems of high temperature resistance of the torch when hydrogen fuel is burned, so that it has the characteristics of "light, solid and beautiful" and can be used normally in a hydrogen combustion environment above 800 degrees Celsius
Compared with the cold metal torch shell "flying" more so that the torchbearer feels warm to help the "Green Olympics"
Carbon fiber technology has strict technical barriers Sinopec Shanghai Petrochemical is the earliest domestic research and development of carbon fiber and industrial production of enterprises as early as 2012 the company used the independent research and development of carbon fiber complete sets of technology to produce 12K small tow carbon fiber in 2018, the company successfully trial production of 48K large tow carbon fiber with international advanced level
The carbon fiber technology developed by Sinopec with independent intellectual property rights currently ranks first in China and third in the world

In the carbon fiber industry, the number of carbon fiber roots per bundle is usually greater than 48,000 (referred to as 48K) is called large tow carbon fiber. At present, each bundle of carbon fiber in China is basically between 1,000 and 12,000, which is called a small tow.
The biggest advantage of 48K large tow is that under the same production conditions, it can greatly improve the single-line production capacity and quality performance of carbon fiber, and realize low production costs, thereby breaking the application limitations brought about by the high price of carbon fiber.
