Carbon fiber composite material makes the torch "fly" to light up the Chinese wisdom of the Beijing Winter Olympics

Editor 's note The 24th Winter Olympics will be held in Beijing from February 4th to 20th.

Earlier, at the one-year countdown to the opening of the Beijing Winter Olympics, the "Flying" torch was unveiled

Behind the "flying" torch is the strength of scientific and technological research and development in China's chemical industry and the collective wisdom of scientific and technological workers

Sinopec shoulders the responsibility of the industrial chain chain, leading Donghua University, China National Nuclear Corporation, Aerospace Science and Technology, Aerospace Science and Industry Group and other units to carry out the research and development and mass production of the Winter Olympics torch, realizing the world's first Olympic Games made of carbon fiber composite materials Torch casing

Back in 2018, Shanghai Petrochemical welcomed a special visiting group, including some sports people

Huang Xiangyu, deputy general manager of Shanghai Petrochemical and carbon fiber expert, said proudly when introducing Sinopec's carbon fiber technology: "The quality of carbon fiber is only about 1/4 of that of steel, but its strength is 7 to 9 times that of steel

In April 2020, the Beijing Winter Olympics Organizing Committee openly solicited the design scheme of the torch from the whole society

　　On September 22, 2020, it was decided by the Beijing Winter Olympics Organizing Committee Chairman's Office that the work named "Feiyang" became the torch design scheme for the Beijing Winter Olympics and Winter Paralympics, and it was decided to innovatively use hydrogen energy and carbon fiber.

　　But when they saw the 3D printed torch samples, they were all dumbfounded

　　The attacking team is divided into two groups

　　Within 3 months of the development of the torch shell, the research team overcame a number of technical problems one by one, and formed a one-stop solution from carbon fiber production, composite material preparation to product end application

　　In order to solve this problem, Shanghai Petrochemical and the Eighth Institute of Nuclear Power of China National Nuclear Corporation jointly tackled key problems, introduced high-performance resins to make carbon fiber composite materials, and finally through process adjustment, the combustion end of the upper half of the torch was subjected to special treatment at a high temperature above 1000 °C to solve the problem.

　　After the official release of the "Flying" torch, the Winter Olympic torch with both traditional Chinese characteristics and modern technological content has been unanimously recognized and highly appraised

　　In the end, after expert appraisal and practical test, the carbon fiber hydrogen torch has high safety and reliability, can resist 10-level strong wind and heavy rain, and can be used in extremely cold weather
.

　　After going through the "nine, nine and eighty-one difficulties", they finally handed over a perfect answer sheet.
The Shanghai Petrochemical Torch Research Team has not had time to celebrate, and the new task has arrived: In March 2021, the Beijing Winter Olympics Organizing Committee proposed that Sinopec will use Beijing Winter As the official partner of the Olympic Games, it undertakes the mass production project of the hand-held torch
.

　　After the Beijing Winter Olympics Organizing Committee, Sinopec Shanghai Petrochemical Co.
, Ltd.
organized on-site inspection and sample testing and verification, the company has finally determined the components of the Winter Olympics torch.
The overall process of delivering products as a whole has been quickly established and operated in five bases in Shanghai, Beijing, Jiangsu, Guangdong and Hebei
.

　　In mid-September 2021, the mass production samples of propane torches used for the collection of the Winter Olympics passed two on-site inspections and third-party verification and acceptance organized by the Beijing Winter Olympics Organizing Committee
.
On September 22, 2021, Shanghai Petrochemical officially delivered 115 propane torches and some peripheral products such as kindling lamps and igniters to the Beijing Winter Olympics Organizing Committee, successfully completing the first batch of mass production tasks delivered by the Beijing Winter Olympics Organizing Committee
.
As planned, another 1,200 torches will arrive in Beijing by mid-January 2022
