The torch wears a carbon fiber "coat":
Combustion temperature ＞ 800 degree , normal use in hydrogen environment
Sinopec's Shanghai Petrochemical put on a carbon fiber "coat" for the torch of Beijing 2022 Winter Olympic Games and winter Paralympic Games. It is the first time in the world to make the Olympic torch shell with carbon fiber composite materials, which solves the technical problem of high temperature resistance of the torch when burning hydrogen fuel, making it "light, solid and beautiful", Realize normal use in hydrogen combustion environment higher than 800 degree . Shanghai Petrochemical and the eighth Nuclear Power Research Institute worked together to tackle key problems, introduced high-performance resin and made carbon fiber composites together with carbon fiber. Finally, through process adjustment, the combustion end of the upper half of the flare was vitrified at a high temperature above 1000 degree , which effectively solved the problems such as blistering and cracking of the flare shell in the process of high-temperature preparation, and met the requirements of both temperature resistance and fire resistance. Compared with the cold metal torch shell, "flying" makes the torchbearers feel warm and contributes to the "Green Olympics".
Poste luminoso de fibra de carbono en la ceremonia inaugural de los Juegos Olímpicos de Invierno:
Peso ligero, alta resistencia y buena operabilidad.
Según el utilero de la ceremonia de apertura de los Juegos Olímpicos de Invierno, el poste luminoso utilizado para la ceremonia de apertura adopta un material compuesto de fibra de carbono, que mide 9,5 metros de largo, 3,8 cm de diámetro en el extremo de la cabeza y 1,8 cm de diámetro en el extremo. , y pesa 3 kg y 7 Liang. Este poste aparentemente ordinario no solo está lleno de ciencia y tecnología, sino también de la estética china de combinar dureza y suavidad. El poste luminoso original es un poste de apoyo de acero inoxidable, con un peso de 6 kg. Aunque el peso es pequeño, la longitud es demasiado larga, lo que provoca fuertes sacudidas del poste y es difícil de controlar. El peso ligero y la alta resistencia de los materiales compuestos no solo se utilizan en el grupo de cañas de pescar, sino también al final.
Patines de velocidad de fibra de carbono impresos en 3D domésticos:
3 por ciento - 4 por ciento de reducción de peso
Yang Jintian, a professor of sports biomechanics at Hebei University of economics and trade, and his research team have established a database of Speed Skaters' foot shape and plantar, and a plantar 3D scanning and printing system. It took more than one year to successfully develop the first generation of high-performance carbon fiber composite speed skates. Compared with China's high-end speed skating skates, the weight of carbon fiber skates is reduced by 3 percent - 4 percent , and the peel strength of skates is increased by 7 percent . Professor Yang Jintian said that the team will promote the iteration of skates. The second generation of domestic skates will be able to compete with similar foreign products, realize the "curve overtaking" of imported brands, and enhance the "technical strength" for the development of ice and snow sports in China.
Moto de nieve doméstica compuesta de fibra de carbono tg800 doméstica:
Baje el centro de gravedad para mayor estabilidad
In order to make the domestic snowmobile known as "F1 on ice" run at high speed, the materials used in the snowmobile body are light in weight and high in strength. Therefore, the manufacturing of snowmobile aims at carbon fiber composites and adopts high-strength domestic tg800 aerospace grade carbon fiber composites. The material is produced by TISCO Steel Co., Ltd. and can be used to make snowmobile and snowmobile helmet. After adopting carbon fiber composite materials, the snowmobile can reduce the body weight and center of gravity to the greatest extent on the premise of ensuring the safety of athletes, so as to make the snowmobile slide more smoothly. It is reported that the body weight of the carbon fiber composite double snowmobile is only about 50kg.
Casco de esquí:
El rendimiento de protección es al menos un 20 por ciento más alto que el estándar europeo
The scientific research team of Dalian University of technology designed a ski helmet with new materials synthesized from carbon fiber, glass fiber and elastomer, which increased its stiffness by four times and its tensile strength by three times. Its shell is similar to the common curved wall panel in the rocket, which can play the effect of "pulling a thousand catties in four or two". The helmet weighs only about 700 grams, and its protective performance is at least 20 percent higher than the European standard without significantly increasing the weight and thickness. The helmet also fully takes into account the head shape characteristics of Asians. The team collected a large number of head shape data of national team athletes and developed design software, which realized the customization of athletes' helmets and effectively improved the comfort of wearing for a long time
Cable calefactor de fibra de carbono:
La conversión directa reduce la pérdida de calor
Carbon fiber heating cables are laid under the floor of the apartment rooms where the athletes of the Winter Olympic Games and the winter Paralympic Games live. Electric heating is used in winter to directly convert electric energy into heat energy and reduce heat loss. All the electric energy used comes from wind power generation in Zhangjiakou, which is clean, renewable and green. The staff of the operation Department of the Olympic Village said that Zhangjiakou Winter Olympic village was built in accordance with China's highest three-star standard of green construction. By taking a series of land-saving, energy-saving, material-saving and water-saving measures, the Winter Olympic village can not only meet the concept of Green Olympics, but also fully meet the needs of the Winter Olympic Games.
Palo de hockey sobre hielo de fibra de carbono:
Duradero y no fácil de romper.
Los palos de hockey sobre hielo de fibra de carbono utilizados por los atletas son más duraderos que los palos de hockey sobre hielo ordinarios después de la aplicación del agente formador de fluidos. De acuerdo con el personal de RD, el recubrimiento de agente formador de fluidos en la superficie del palo de hockey de fibra de carbono puede aumentar la dureza de la tela de fibra de carbono por un lado y mejorar la resistencia estructural general del palo por el otro. Al proporcionar un agente formador de fluidos de baja fluidez, y cuando la presión de inflado del molde es constante, puede garantizar que aún haya suficiente agente formador de fluidos adherido a la superficie del sustrato del club de fibra de carbono y participar en el proceso de formación posterior. Una cantidad suficiente de agente formador de fluidos puede garantizar la dureza del palo de hockey, de modo que los jugadores no sean fáciles de romper o romper el palo al balancearlo. Asegúrese de que el palo de hockey sea fuerte y duradero.
De hecho, además del crecimiento constante en la demanda de compuestos de fibra de carbono en industrias tradicionales como deportes y ocio, aeroespacial, etc., el campo de la energía dominado por la transmisión de energía y la energía eólica y el campo del transporte dominado por el automóvil y el transporte ferroviario. también han inyectado nueva vitalidad en el desarrollo de la industria de la fibra de carbono. La economía verde y baja en-carbono tiene un efecto de atracción significativo en la aplicación de fibra de carbono, y también promueve que la industria textil industrial entre en una nueva etapa de aplicación industrial.
