In the field of wind turbine blade, carbon fiber is mainly applied to the main beam of wind turbine blade in the form of pulling and squeezing plate.
Compared with glass fiber, the density of carbon fiber is about 30% smaller than that of glass fiber. The V-90 type 3.0MW fan blade produced by wind power giant Vestas has achieved the effect of weight reduction of 32% and 16% lower than that of glass fiber. According to Sandia Laboratory in the United States, after replacing the 100-meter-long wind turbine blade main beam from glass fiber with carbon fiber, carbon fiber accounted for about 12.4% of the blade mass, and the total weight of the blade decreased by 28%, while the material cost only increased by about 9% (the price of carbon fiber for wind power is about $15 / kg). Previously, due to the high cost of carbon fiber, the use of carbon fiber in wind power blades is low. In the future, with the acceleration of the trend of large fan blades and the further reduction of the cost of carbon fiber in the civil field, the permeability of carbon fiber in wind power blades will continue to increase.
In the aviation field, carbon fiber materials are used in all levels of aircraft structure
Compared with traditional space metal alloy materials, carbon fiber composites have higher specific strength, specific modulus, fatigue resistance and corrosion resistance, and can withstand the pressure and climate conditions of aircraft when flying at high speed. Aviation field of carbon fiber composite materials mainly use hot pressing tank molding process. The good molding ability of carbon fiber composite materials can greatly reduce the structural design cost and manufacturing cost. At present, carbon fiber composites have been successfully used in the aircraft fuselage, wings, engine fan blades and shell, engine cabin, engine cabin materials and other levels.

In the field of automobile, carbon fiber composite material has a significant effect on energy saving, emission reduction and endurance improvement of automobile.
Similar to the aviation industry, the lightweight of the automotive industry can bring great economic benefits and performance improvements. According to the European Aluminum Association, when the quality of cars is reduced by 10%, the efficiency of energy use can be increased by 6-8%, reduce emissions per 100 kilometers by 10%, and increase tire life by 7%. For fuel vehicles, when the vehicle quality is reduced by 100 KG, it can save the fuel consumption of 0.3-0.6L/ 100 km, and then reduce the carbon dioxide emission of 10g / km; for new energy vehicles, the weight reduction of 100 KG can increase its endurance by about 6% -11%.besides,
For hydrogen cars, some models of hydrogen storage bottles have begun to use carbon fiber materials, compared with traditional type I bottles and bottles,
The bottles and bottle greatly increase the pressure and hydrogen storage density that the hydrogen storage bottle can withstand, which means the energy under the same volume
Enough to store more hydrogen to improve the car's range.

The factor still lies in its high cost and processing difficulty. Its price is ten times higher than glass fiber composite materials, compared to high strength steel
There is also an obvious gap with magnesium aluminum titanium alloy, and the high process difficulty also limits its rapid and continuous production process, so
Current models using carbon fiber composites are still high-end.
At present, the new industrialization alliance mode of "automobile manufacturer + CFRP parts supplier" has begun to rise. As in the Prodrive

T-RTM and other original molding process are constantly upgraded and optimized. In the production and assembly of automotive carbon fiber composite materials, the materials are made of
This accounts for about 30%, and with the rise of the alliance model, we expect the production of carbon fiber composite components in the future
It is expected to gradually decrease, and its penetration rate in vehicle materials is expected to continue to increase.
Demand for automotive carbon fiber is growing rapidly and is expected to exceed 20,000 tons by 2024. According to the forecast of the China Association of Automobile Manufacturers, the production of new energy vehicles will still maintain a high growth rate in the next five years, and the global and Chinese production of new energy vehicles will reach respectively in 2025
