1. Carbon fiber + wind power
Many studies at home and abroad have shown that carbon fiber reinforced composites can give play to the advantages of high elasticity and light weight in large wind turbine blades. The larger the external size of the blade, the more obvious this advantage is. Compared with glass fiber material, the blade weight of carbon fiber composite material can be reduced by at least about 30%. The reduction of blade weight and the increase of stiffness are conducive to improve the aerodynamic performance of the blade, reduce the load on the tower and axle, make the power output of the fan more balanced and stable, and have higher energy output efficiency. If the conductivity of carbon fiber material can be effectively used in the structural design, the damage to the blade caused by lightning can be avoided. Moreover, carbon fiber composites have good fatigue resistance, which is conducive to the long-term operation of wind blades in harsh weather conditions.
2. Carbon fiber + lithium battery
In the manufacturing of lithium batteries, a new trend of large-scale replacement of traditional metal rollers with carbon fiber composite rollers has been formed, which is guided by "energy conservation, emission reduction and quality improvement". The application of new materials is conducive to improving the added value of the industry and further improving the market competitiveness of products. At present, carbon fiber roller has made a comprehensive breakthrough in the field of lithium battery manufacturing. It is reported that based on the core business of carbon fiber composite lightweight, some new materials technology focuses on providing customers in the field of industrial "intelligent manufacturing" with one-stop finished carbon fiber parts and components services including material R & D, sample trial production, process scheme optimization and mass production delivery. At present, one of such company has delivered more than 500000 sets of high-strength carbon fiber composite rollers for major domestic lithium battery leading enterprises. The mass production of the project proves that carbon fiber composite has the foundation for large-scale application in domestic industrial field.
3. Carbon fiber + photovoltaic
The characteristics of carbon fiber composites such as high strength, high modulus and low density have also received corresponding attention in the photovoltaic industry. Although they are not as widely used as carbon fiber composites, their application in some key parts is also gradually promoted, such as using carbon fiber composites to make silicon wafer supports. Another example is carbon fiber scraping film. In the production of photovoltaic cells, the lighter the scraping film is, the easier it is to be refined, and a good screen printing effect plays a positive role in improving the conversion effect of photovoltaic cells. The high-temperature resistant carbon fiber plates customized by Zhishang new materials technology, a domestic carbon fiber parts manufacturer, can avoid the defect that the general epoxy resin based carbon fiber composite is not resistant to high temperature, and plays a unique advantage in improving the photovoltaic manufacturing capacity and process level.
4. Carbon fiber + hydrogen energy
The first batch of hydrogen commuter buses developed by Yutong group and SINOCHEM hydrogen energy Co., Ltd. for the 2022 Beijing Winter Olympic Games serve the urban area of Beijing. The 165l hydrogen storage cylinder group is used in the three competition areas of Yanqing and Zhangjiakou in Beijing, which can be filled with hydrogen in 15 minutes, and the designed endurance mileage can reach 630km, which can take three round trips. It can also operate normally at a low temperature of minus 30 degrees. This time, all the materials, components and systems of hydrogen energy vehicles are domestic and autonomous. After the electrochemical reaction of hydrogen and oxygen, the product released is 100% pure water. Compared with traditional vehicles, the energy conversion rate of hydrogen energy battery is as high as 60% - 80%, which is 2-3 times that of internal combustion engine. Hydrogen is produced from wind power and photovoltaic renewable energy. It is taken from nature and returned to nature, truly realizing zero carbon emission.
