Application of carbon fiber composite materials in the field of new energy
High performance carbon fiber composite materials are typical representatives of advanced composite materials. As an integrated material of structure and function, carbon fiber composite materials play a very important role in new energy fields such as power industry, petroleum industry, natural gas, electric vehicles, etc. Compared to traditional fossil fuels, the application of carbon fiber composite materials in the new energy industry is an inevitable direction that conforms to the theme of the times, based on new materials and technologies, including renewable energy such as wind energy, ocean energy, geothermal energy, nuclear energy, solar energy, and new energy formed by the transformation of traditional energy technologies.
Application of carbon fiber in natural gas field
Compressed Natural Gas (CNG) is widely used in China, which is safe, low-cost, and pollution-free, making it an ideal energy source for us. Gas cylinders are storage containers for CNG and are key components of CNG. This type of gas cylinder can be made of alloy or composite materials. Compared to steel cylinders, carbon fiber composite gas cylinders have better safety when damaged. When composite gas cylinders are overloaded, a small amount of fiber breakage may occur, and the pressure load will quickly redistribute on the undamaged fibers, without causing the cylinder to push its load-bearing capacity in the short term.
The application of carbon fiber in the field of wind power
The price of wind power is related to the function of wind turbines, and within a certain range, they are inversely proportional, which means that the higher the motor power, the lower the cost per unit of electricity generated. One of the key components of a wind turbine is the blade, and the length of the blade plays an important role in the power of the wind turbine. Improving the power of the generator requires high requirements for the length, quality, and material strength of the blades. It is imperative to adopt carbon fiber composite materials with better performance when developing larger power wind power generation devices and longer rotor blades.
At present, many companies around the world have started to apply it, such as German blade manufacturers using newly manufactured 56m long, 5MW wind turbine blades made of carbon fiber. With the support of new forming processing technologies, carbon fiber composite materials will definitely play an increasingly important role in power production. In addition, there is a huge potential market for carbon fiber composite conductors in power transmission lines. Carbon fiber composite conductors can improve the efficiency of transmitting electrical energy and are also an important area of energy utilization.
The application of carbon fiber in the field of electric vehicles
Composite materials have low energy consumption, lightweight and high strength, and good formability, making them an ideal material for the automotive industry to replace steel with plastic. At present, the automobile industry is flourishing unprecedentedly, but it is also facing huge challenges in resources and environment. How to promote automobile lightweighting to achieve the goal of reducing fuel consumption is the theme of the development of the automobile industry.
Because carbon fiber composite materials have thermosetting and thermoplastic properties, they can be applied to different automotive components. Internationally, carbon fiber composite materials have been applied to various components of automobiles, including body parts, power parts, and more. It is worth mentioning that achieving the large-scale application of carbon fiber composite materials in automobiles requires breakthroughs in many key technologies.
The application of carbon fiber in the petroleum industry
In China, mechanical oil extraction wells account for over 90% of the total production wells, of which 80% use traditional rod pump pumping mode. This type of metal sucker rod has the disadvantages of high weight, easy corrosion, low fatigue performance, and high incidence of oil production accidents. However, the use of carbon fiber composite material continuous sucker rod completely overcomes these disadvantages and has the characteristics of high strength, light weight, corrosion resistance, and wear resistance, greatly improving oil production efficiency and having a wide range of application prospects. It cannot be ignored that deep-sea oil and gas extraction is the trend of oil development in the world today, and China has abundant deep-sea oil. Better and faster development of deep-sea oil and gas is also an important issue in China's current oil strategy development.
At present, the depth of sea mining in China has reached 1500-3000m, and the continuous deepening of the depth has brought difficult technical problems to the existing mining equipment and technology. It can be seen that in the field of deep-sea oil and gas development, the research and development of carbon fiber composite components is an inevitable direction for future development. The energy conservation and new energy industry is an industry that urgently needs rapid development in China today, and it is a highly promising industry with great development prospects. The new energy industry, as a key force supporting China's economy to smoothly move towards a low-carbon and green path, and to strive for the technological and economic high ground in international competition, should receive sufficient attention and development.
To realize the application of carbon fiber composite materials in the new energy industry, it is necessary to fully understand the superior performance of carbon fiber composite materials, develop low-cost carbon fiber forming technology, and develop the terminal industry chain in the power industry, petroleum industry, natural gas industry, and electric vehicle industry. With more and more understanding and mature technology, carbon fiber composite materials will definitely play an increasingly important role in the new energy industry.
