How can a drop of oil "turn" into a Winter Olympic torch?
yes! You read that right!
Beijing 2022 Winter Olympics
The shell of the torch "flying"
Made of carbon fiber developed with the participation of Sinopec
For the first time in the world
The Olympic torch shell is made of carbon fiber composite material
It turns out that "this drop of oil" is -
Carbon fiber!!!
Carbon fiber, also known as "black gold". It is "of the same origin" as the masks we wear every day, and they all come from the black oil buried in the rock formation hundreds of millions of years ago.
Carbon fiber is a high-strength new fiber material with a carbon content of more than 95%. Excellent mechanical properties, quality is a quarter of steel, strength is 7 to 9 times that of steel, and also has the characteristics of corrosion resistance and high modulus, known as the "king of new materials", has a wide range of application prospects in all walks of life.
Sinopec carbon fiber is not only used in the Winter Olympic torch
It is also found on the new high-speed train
Carbon fiber is successfully applied to the "Bay Area Blue" high-speed train of Guangzhou Metro Line 18, the performance is fully in line with the operating conditions, the use of carbon fiber composite materials of the train head cover, compared with the aluminum alloy material of the same module, can reduce the weight by up to 35% to 40%, effectively help the train to reduce weight and speed.
Sinopec also put on a carbon fiber "coat" for the Beijing 2022 Winter Olympics torch "Flying", which is the world's first realization of the production of the Olympic torch shell with carbon fiber composite materials, which solves the technical problems of the torch needing to withstand high temperature when hydrogen fuel is burned, so that it has the characteristics of "light, solid and beautiful", and can achieve normal use in the hydrogen combustion environment above 800 degrees Celsius.
Guangzhou Metro Line 18 is known as the fastest subway in the Guangdong-Hong Kong-Macao Greater Bay Area, with a maximum speed of 160 kilometers per hour, and the "Bay Area Blue" train, which is the first in China, uses lightweight, high-strength carbon fiber composite materials for the hood. Since 2019, Sinopec and CRRC have carried out collaborative innovation, overcome the key core technologies of carbon fiber composites in the field of rail transit, established a complete technology research and development system, formed the world's leading "one-stop" lightweight technology solution, and finally realized the successful application of carbon fiber composites on the "Bay Area Blue" train.
Sinopec carbon fiber will also be applied on the guangzhou metro line 22 train. 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, opening up a broader field for the development of the industrial chain of carbon fiber and its composite materials in mainland China.
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 self-developed carbon fiber complete set 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 Sinopec has independent intellectual property rights to develop carbon fiber technology, and currently ranks first in China and third in the world.
