High-performance carbon composites are typical representatives of advanced composites. As an integrated material of structure and function, carbon fibre composites play a very important role in new energy fields such as electric power industry, petroleum industry, natural gas and electric vehicles. Relative to the traditional fossil energy in terms of new energy, with new materials and new technologies as the basis, including wind energy, ocean energy, geothermal energy, nuclear energy, solar energy and other renewable energy sources, as well as changes in traditional energy technology to form a new energy source, etc., carbon fibre composite materials in the new energy industry is in line with the theme of the times the inevitable direction of the development of carbon fibre composite materials in the field of natural gas, natural gas, electric vehicles, and other new energy fields.

Application of carbon fibre in the field of natural gas

Compressed Natural Gas (Compressed NaturalGas, CNG) is widely used in our country, it is safer to use, low cost, no pollution, it is a more ideal energy. Gas cylinder is the storage container of CNG, which is the key component of CNG. This kind of cylinder is alloy steel cylinder or composite material cylinder can be. Relative to steel cylinders, carbon fibre composite cylinders breakage security is good, when the composite cylinder overload may occur a small amount of fibre fracture, at this time the pressure load will be quickly redistributed in the undamaged fibres, not resulting in the cylinder in the short term to promote the carrying capacity.

Carbon fibre in the field of wind power

The price of wind power is related to the function of the wind turbine, within a certain range they are inversely proportional to the relationship, that is to say, the higher the power of the motor, the lower the cost per unit of power generation. 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 turbine.

Increasing the power of the generator has high requirements on the length, quality and material strength of the blades. In the development of higher power wind turbines and longer rotor blades, the use of carbon fibre composites with better performance is imperative.

At present, there are already a lot of companies around the world have begun to apply, such as: Germany blade manufacturer used carbon fibre new manufacturing 56m long, 5MW wind turbine blade. Together with the new moulding processing technology support, carbon fibre composites in power production will certainly play up the more important role. In addition, carbon fibre composite conductor transmission conductor there is also a huge potential market, carbon fibre composite conductor can improve the efficiency of transmission of electricity, but also an important area of energy use.

Carbon fibre in the field of electric vehicles

Composite materials processing low energy consumption, and lightweight and high strength, good moulding process, has been the automotive industry to plastic instead of steel ideal material. At present, the automobile industry is unprecedentedly prosperous, but is also facing a huge challenge of resources and the environment, how to promote automobile lightweight to achieve the purpose of reducing fuel consumption, is the theme of the development of the automobile industry.

Carbon fibre composites can be applied to different automotive parts because of their thermosetting and thermoplastic properties. Internationally, carbon fibre composites have been applied to various parts of automobiles, including body parts, power parts and so on. It is worth mentioning that there are many key technologies that need to be broken through in order to achieve real large-scale application of carbon fibre composites in automobiles.

Carbon fibre in the oil field

Oil is a very valuable energy source, but also a limited and non-renewable energy source, today's comprehensive national power competition is an important factor. In China, the number of mechanical oil recovery wells accounted for more than 90% of the total number of production wells, in which 80% is the use of traditional rod pumping mode.

This metal pumping rod exists a large weight, easy to corrode, low fatigue performance, high incidence of oil recovery accidents shortcomings, and the use of carbon fibre composite continuous pumping rods thoroughly restrain these shortcomings, with high strength, light weight, corrosion resistance, abrasion resistance, greatly improving the oil recovery efficiency, the prospects for a wide range of applications.

Can not be ignored is that the deep sea oil and gas exploitation is the trend of today's world oil development, and China's deep sea oil is richer, better and faster development of deep sea oil and gas is also an important issue of China's current oil strategy development.

At present, China's exploitation of the sea depth has reached 1500~3000m, the depth of the deepening of the original mining equipment and technology has brought difficult to overcome the technical problems. This shows that in the field of deep sea oil and gas development, the research and development of carbon fibre composite components is the inevitable direction of future development.

Energy-saving and new energy industry is an industry that needs to be developed rapidly in China, and energy-saving and new energy industry is an industry with great development prospect in China. As a key force to support China's economy to move smoothly towards the low-carbon and green road and to fight for the scientific and technological economic commanding heights in the international competition, the new energy industry should be given enough attention and development.

To realize the application of carbon fibre composites in the new energy industry, first of all, it is necessary to fully understand the superior performance of carbon fibre composites, develop low-cost carbon fibre moulding technology.
