On February 4, 2022, as the Beijing Winter Olympics commenced as scheduled, we cheered on the Olympic athletes with excitement, and a series of ice and snow sports equipment with independent intellectual property rights in carbon fiber technology also caught our attention. Let's take a closer look at this high-end equipment.

To enable the "F1 on Ice" to reach high speeds, the bobsleigh's body requires lightweight and high-strength materials.  These materials are widely used in the aerospace industry. Therefore, bobsleigh manufacturers have focused on carbon fiber composite materials, a new type of material first developed and used in the aerospace field.  They have specifically adopted high-strength, domestically produced TG800 aerospace-grade carbon fiber composite materials. Using carbon fiber composites allows the bobsleigh to minimize body weight and lower its center of gravity while ensuring athlete safety, resulting in a more stable ride. According to reports, the two-person bobsleigh body made of carbon fiber composite materials weighs only about 50 kilograms. The high strength and unique energy-absorbing properties of the material also protect athletes from injury in the event of a crash.

This is the first time in the world that a torch casing for the Olympic Games has been made from carbon fiber composite materials.  This solves the technical challenge of the torch needing to withstand high temperatures during hydrogen fuel combustion, resulting in a torch that is lightweight, durable, and aesthetically pleasing. It can function normally in a hydrogen combustion environment exceeding 800 degrees Celsius. Compared to the cold metal torch casings of the past, the "Flying" torch provides a warmer feel for the torchbearers, contributing to a "green Olympics."

Measuring 9.5 meters in length, with a diameter of 3.8 centimeters at one end and 1.8 centimeters at the other, and weighing 3 catties and 7 taels (approximately 1.85 catties), this seemingly ordinary pole is not only full of technological sophistication but also embodies the harmonious blend of strength and grace characteristic of Chinese aesthetics.

At this Winter Olympics, carbon fiber hydrogen energy products shone brightly: hydrogen fuel cell vehicles equipped with hydrogen storage tanks were deployed in batches to serve the Yanqing and Zhangjiakou competition zones in Beijing, contributing to the 2022 Winter Olympics; the first batch of hydrogen-powered commuter buses, jointly developed by Yutong Group and State Power Investment Corporation Hydrogen Energy Company, uses 165L hydrogen storage tank assemblies and has a designed range of up to 630 kilometers.

Hydrogen energy products not only served the Winter Olympics transportation sector, but also included refrigerated logistics vehicles using 165L hydrogen storage tank assemblies to provide logistics services inside and outside the competition zones, while hydrogen fuel cell police patrol cars, fire patrol cars, and postal vehicles used 53L hydrogen storage tanks. In the field of hydrogen fuel cell vehicles, the improvement of on-board hydrogen storage technology will be a key breakthrough in the future development of hydrogen fuel cell vehicles, and the hydrogen storage tank is one of the critical components in the entire on-board hydrogen supply system. Among these, carbon fiber-reinforced composite hydrogen storage tanks are highly anticipated.

Compared to high-end Chinese speed skating boots, carbon fiber boots are 3%-4% lighter, and their delamination strength is increased by 7%.

The carbon fiber composite material used as the base material for ice hockey sticks employs a manufacturing process that involves mixing a fluid molding agent into the carbon fiber fabric during its production. This process reduces the fluidity of the molding agent below a preset threshold and controls the mass error of the carbon fiber fabric to within ±1g/m² to 1.5g/m². The carbon fiber base material is then placed in a mold, where the inflation pressure is controlled between 18000 Kpa and 23000 Kpa, and the carbon fiber base material is heated to form the ice hockey stick. The fluid molding agent adheres to the surface of the carbon fiber fabric, increasing the toughness of the fabric and enhancing the overall structural strength of the stick. By providing a low-fluidity molding agent and maintaining a constant mold inflation pressure, sufficient molding agent remains attached to the surface of the carbon fiber base material and participates in the subsequent molding process. This ample amount of molding agent ensures the toughness of the ice hockey stick, preventing cracking or breakage during use and ensuring its durability.
