The 24th Winter Olympic Games ended in Beijing a few days ago, and the winter Paralympic Games will also begin on March 4. The wonderful stories of the Winter Olympics and Paralympic Games are staged one after another. Among them, the scientific and technological elements related to industrial textiles are extremely prominent, with many highlights. Many new materials contributed to these two international events and helped China to host the Olympic Games in green and science and technology.
Stimulated by multiple factors such as the high attention of the state and the concentration of investment in high-tech fields, China's carbon fiber composite technology and industrial development have made gratifying achievements, which have made great achievements in the current Winter Olympic Games and winter Paralympic Games. These star products will appear in the 16th China International Industrial Textiles and nonwovens exhibition of cinte22.
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".
Carbon fiber luminous pole at the opening ceremony of the Winter Olympic Games:
Light weight, high strength and good operability
According to the propsman of the opening ceremony of the Winter Olympic Games, the luminous pole used for the opening ceremony adopts carbon fiber composite material, which is 9.5 meters long, 3.8 cm in diameter at the head end, 1.8 cm in diameter at the end, and weighs 3 kg and 7 Liang. This seemingly ordinary pole is not only full of science and technology, but also full of Chinese aesthetics of combining hardness and softness. The original luminous pole is a stainless steel prop pole, weighing 6 kg. Although the weight is small, the length is too long, resulting in severe shaking of the pole and difficult to control. The light weight and high strength of the composite materials are not only used in the fishing rod group, but also in the end.
Domestic 3D printed carbon fiber speed skates:
3 percent - 4 percent weight reduction
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.
Domestic tg800 carbon fiber composite domestic snowmobile:
Lower the center of gravity for more stability
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.
Ski helmet:
The protection performance is at least 20 percent higher than the European standard
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
Carbon fiber heating cable:
Direct conversion reduces heat loss
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.
Carbon fiber Ice Hockey Club:
Durable and not easy to break
The carbon fiber ice hockey sticks used by athletes are more durable than ordinary ice hockey sticks after the application of fluid forming agent. According to the R D personnel, coating fluid forming agent on the surface of carbon fiber Hockey Club can increase the toughness of carbon fiber cloth on the one hand and improve the overall structural strength of the club on the other hand. By providing a low fluidity fluid forming agent, and when the inflation pressure of the mold is constant, it can ensure that there is still enough fluid forming agent attached to the surface of the carbon fiber Club substrate, and participate in the subsequent forming process. Sufficient fluid forming agent can ensure the toughness of the hockey club, so that the players are not easy to crack or break the club when swinging the hockey club, Make sure the hockey stick is strong and durable.
In fact, in addition to the steady growth in the demand for carbon fiber composites in traditional industries such as sports and leisure, aerospace and so on, the energy field dominated by power transmission and wind power and the transportation field dominated by automobile and rail transportation have also injected new vitality into the development of carbon fiber industry. The low-carbon and green economy has a significant pulling effect on the application of carbon fiber, and also promotes the industrial textile industry to enter a new stage of industrial application.
At the beginning of the Spring Festival, what opportunities will industrial textiles and nonwovens usher in? From September 6 to 8, 2022, cinte22's 16th China International Industrial Textiles and nonwovens exhibition will show the latest products and technologies in this field.
Gather global industry leaders, let's look forward to it.
