The holding of the Beijing Winter Olympics attracted worldwide attention. A series of ice and snow equipment and core technologies with independent intellectual property rights of carbon fiber are also amazing. The following section on carbon fiber production technology makes an inventory of equipment made of carbon fiber materials.
1. The snowmobile and snowmobile helmet made of TG800 carbon fiber produced by Shanxi Steel Science and Technology Co., Ltd. contribute to the Beijing Winter Olympic Games
The snowmobile and snowmobile helmet made of TG800 carbon fiber produced by Shanxi Gangke Carbon Materials Co., Ltd. of China Baowu Taigang Group will help athletes achieve better results. "In the past nine years, the company has realized the development process of technology and variety from scratch to all; in 2021, the high-end carbon fiber project with an annual output of 1800 tons will be put into operation, and this year, the fourth phase of the project will also be completed and put into operation." The person in charge of Shanxi Gangke Carbon Materials Co., Ltd., Changchun News, said that TISCO will continue to invest in the construction of two 2000 ton production lines and one test line in the future. By the end of the "14th Five Year Plan", it will achieve an annual output of 6000 tons of high-end carbon fiber, and a long-term output of 10000 tons.
2. Shanghai Petrochemical has put on the carbon fiber "coat" for the "flying" of the torch of the Winter Olympics
Sinopec Shanghai Petrochemical has put a carbon fiber "coat" on the torch of the Beijing 2022 Winter Olympic Games. It is the first time in the world that the Olympic torch shell is made of carbon fiber composite materials. It solves the technical problem that the torch needs high temperature resistance when burning hydrogen fuel, making it "light, solid and beautiful". It can be used normally in a hydrogen burning 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 technology has strict technical barriers. Sinopec Shanghai Petrochemical Co., Ltd. is an enterprise that has developed carbon fiber and carried out industrial production earlier in China. As early as 2012, the company produced 12K small tows of carbon fiber using the carbon fiber complete technology independently developed. In 2018, the company successfully trial produced internationally advanced 48K large tow carbon fiber. It is reported that Sinopec has carbon fiber technology developed with independent intellectual property rights, and its patent application ranks first in China and third in the world.
3. The luminous pole at the opening ceremony of the Winter Olympic Games is made of carbon fiber
According to the introduction of the prop designer for the opening ceremony of the Winter Olympic Games, the light-emitting pole used for the opening ceremony is made of carbon fiber composite material, 9.5 meters long, 3.8 cm in diameter at the head end, 1.8 cm in diameter at the end, and weighs 3 jin 7 liang. This seemingly ordinary rod is not only full of science and technology, but also full of Chinese aesthetics of hardness and softness! The original luminous pole is a stainless steel prop pole, weighing 6 kg. Although the weight is not large, the length is too long, which causes the pole to shake severely and is difficult to control. Finally, the prop team thought of the carbon fiber composite widely used in the fishing rod, which is not only light in weight, high in strength, but also better in handling.
4. 3D printed carbon fiber speed skating shoes made in China help the Winter Olympics
In order to change the situation that the world-famous carbon fiber speed skating shoes are monopolized by European and American companies, Yang Jintian, a professor of sports biomechanics at Hebei University of Economics and Trade, and his research team established a database of the foot shape and sole of speed skaters, as well as a foot 3D scanning and printing system. It took more than one year to successfully develop the first generation of high-performance carbon fiber composite speed skating shoes. Compared with China's high-end speed skating shoes, the weight of carbon fiber skates is reduced by 3% - 4%, and the peel strength of skates is increased by 7%. Professor Yang Jintian said that the team would promote the iteration of skates and strive to enter the industrialization stage as soon as possible. He also announced that the second generation of domestic skates will be able to compete with similar foreign products, achieve "curve overtaking" for imported brands, and enhance "technical strength" for the development of ice and snow sports in China.
