On February 11, 2022, recently, the high-performance carbon fiber developed and produced by SHSH Advanced Material Technology Corproation was successfully applied to the "Bay Area Blue" high-speed train of Guangzhou Metro Line 18. Operational data shows that the performance of the train hood using carbon fiber composite material fully meets the operating conditions. Compared with the aluminum alloy material of the same module, the weight can be reduced by 35%-40%, which effectively helps the train to reduce weight and increase speed.
It is reported that SHSH also put a carbon fiber "coat" on the "Flying" torch of the Beijing 2022 Winter Olympics. It is the first time in the world that the Olympic torch shell is made of carbon fiber composite materials. It has the characteristics of "light, solid and beautiful", and can be used normally in a hydrogen combustion environment higher than 800 degrees Celsius. Compared with the cold metal torch shell, "Flying" makes the torchbearers feel warmer and helps the "Green Olympics". .
Carbon fiber is a new type of high-strength fiber material with a carbon content of more than 95%. It has excellent mechanical properties, one quarter of the quality of steel, but seven to nine times the strength of steel, and it also has corrosion resistance. Known as the "king of new materials", also known as "black gold", it can be widely used in aircraft parts, rail transit raw materials, body manufacturing, etc., and has broad application prospects in all walks of life.
It is understood that 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. The "Bay Area Blue" train responsible for the operation task is China's first train head cover made of lightweight and high-strength carbon fiber composite materials. subway train.
Since 2019, SHSH and CRRC have carried out collaborative innovation, conquered the key core technologies for the large-scale application of carbon fiber composite materials in the field of rail transit, established a complete technology research and development system, and formed the world's leading "one-stop" lightweight technology The solution finally realized the successful application of carbon fiber composite materials on the "Bay Area Blue" train.
In the next step, the carbon fiber developed by SHSH will also be applied to the trains of Guangzhou Metro Line 22. In addition, the R&D teams of SHSH and CRRC are also actively carrying out technical research on carbon fiber composite materials applied to higher-performance vehicles such as high-speed trains with a speed of 400 kilometers per hour and maglev trains, which will open up new opportunities for the development of China's carbon fiber and composite materials industry chain. broad field.
Carbon fiber technology has strict technical barriers. SHSH is an early enterprise in China to develop carbon fiber and carry out industrial production.
As early as 2008, the company produced 12K small tow carbon fiber using its self-developed carbon fiber complete technology. In 2016, the company successfully trial-produced 48K large tow carbon fiber with international advanced level. It is reported that SHSH has carbon fiber technology developed with independent intellectual property rights, and currently ranks first in China and third in the world for patent applications.
