On February 4, 2022, the Beijing Winter Olympics was held as scheduled. While we applauded the Olympic athletes with excitement, a series of ice and snow equipment with independent intellectual property rights of carbon fiber also came into sight. Let's take a closer look at these high-end equipment.

In order to enable the "F1 on the ice" to run at high speed, the materials used for the snowmobile body are required to be light in weight and high in strength. Such materials are also widely used in the aerospace field. Therefore, the snowmobile is aimed at the carbon fiber composite, a new material that Z first applied and developed in the aerospace field, and uses the high-strength grade domestic TG800 aerospace grade carbon fiber composite. With the use of carbon fiber composite materials, the snowmobile can greatly reduce the weight of the body, reduce the center of gravity, and make the snowmobile slide more smoothly on the premise of ensuring the safety of athletes. It is reported that the weight of the double snowmobile made of carbon fiber composite is only about 50 kg. The high strength and unique energy absorption characteristics of the material can also protect the athletes from being injured in the crash.

This is the first time in the world that the Olympic torch shell is made of carbon fiber composite materials, which solves the technical problem that the torch needs to be resistant to high temperature when burning hydrogen fuel. It has the characteristics of "light, solid and beautiful", and can be used normally in the hydrogen burning environment above 800 ℃. Compared with the cold metal torch shell, "flying" makes the torchbearer feel warmer and helps the "green Olympics".

It 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 jin and 7 liang. This seemingly ordinary rod is not only full of science and technology, but also full of Chinese aesthetics of combining hardness and softness.

At the Winter Olympic Games, carbon fiber hydrogen energy products shine brilliantly: hydrogen fuel cell vehicles carrying hydrogen storage cylinders have successively served Beijing Yanqing and Zhangjiakou in batches to help the 2022 Winter Olympic Games; The first batch of hydrogen commuter buses jointly developed by Yutong Group and the State Household Appliances Investment Co., Ltd., use 165L hydrogen storage cylinder sets, and the design range can reach 630 kilometers.

Hydrogen energy products not only serve the winter Olympic commuting field, but also provide logistics and transportation services inside and outside the competition area by using 165L hydrogen storage cylinder group logistics heat preservation vehicles, while hydrogen fuel cell police patrol vehicles, fire patrol vehicles and postal vehicles use 53L hydrogen storage cylinders. In the field of hydrogen fuel cell vehicles, the improvement of on-board hydrogen storage technology will be a key breakthrough in the development of hydrogen fuel cell vehicles in the future. In the entire on-board hydrogen supply system, the hydrogen storage bottle is one of the key components. Among them, carbon fiber wound composite hydrogen storage cylinder is expected.

Compared with China's high-end speed skating skates, the weight of carbon fiber skates is reduced by 3% - 4%, and the peeling strength of skates is increased by 7%.

The carbon fiber composite, the base material of hockey pole, adopts the process method of mixing the fluid forming agent into the carbon fiber cloth during the production, which reduces the fluidity of the fluid forming agent to below the preset threshold, and controls the quality error of the carbon fiber cloth within ± 1g/m2 - 1.5g/m2; Put the carbon fiber ball rod base material made of carbon fiber cloth into the mold, control the inflation pressure of the mold at 18000Kpa to 23000Ka, and heat the carbon fiber ball rod base to make the ice hockey rod form. The fluid forming agent is used to attach to the surface of carbon fiber cloth. On the one hand, it increases the toughness of carbon fiber cloth, and on the other hand, it improves the overall structural strength of the ball club. By providing 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 hockey stick base material, and participate in the subsequent forming process. The sufficient fluid forming agent ensures the toughness of the hockey stick, so that players are not easy to crack or break the hockey stick when swinging the hockey stick, so as to ensure the durability of the hockey stick.
