Take you to understand the huge role of carbon fiber
  Under the background of high-speed industrialization in today's world, the use of carbon fiber is becoming more and more diversified. In the occasions requiring high temperature and high physical stability, carbon fiber composite materials have irreplaceable advantages. The higher the specific strength of the material, the smaller the self-weight of the component, and the higher the specific modulus, the greater the stiffness of the component. It is precisely because of its excellent performance that carbon fiber has a wide range of application prospects in national defense and civil fields.

1. Composite materials
  In addition to being used as a thermal insulation material in traditional use, carbon fiber is mostly added to resin, metal, ceramic, concrete and other materials as a reinforcing material to form a composite material. Carbon fiber has become the most important reinforcement material for advanced composite materials. Because carbon fiber composites have the characteristics of lightness and strength, lightness and rigidity, high temperature resistance, corrosion resistance, fatigue resistance, good structural dimensional stability, good design, and large-area integral molding, they have been widely used in aerospace, defense, military and civil industries. are widely used in various fields.
  In addition to woven fiberglass, woven roving mat, woven fiberglass tape, paper and other composite materials. High-performance carbon fiber is also the most important reinforcement for the manufacture of advanced composites.

2. Civil construction
Carbon fiber cloth is also used in the reinforcement and reinforcement of industrial and civil buildings, railway highway bridges, tunnels, chimneys, tower structures, etc. In railway buildings, large-scale roof systems and sound insulation walls will have good applications in the future. It is a promising application of carbon fiber. It has the characteristics of low density, high strength, good durability, strong corrosion resistance, chemical corrosion resistance such as acid and alkali, good flexibility and strong strain capacity. The truss-girder roof made of carbon fiber tubes is about 50% lighter than steel, making large-scale structures practical, and the construction efficiency and seismic performance have been greatly improved. In addition, when carbon fiber is used as a reinforced concrete structure, there is no need to add bolts and rivets to fix it. Compared with chopped fiber for concrete, the disturbance to the original concrete structure is less, and the construction process is simple.
3. Aerospace
  Carbon fiber is an indispensable strategic basic material for cutting-edge weapons and equipment such as rockets, satellites, missiles, fighter jets and ships. The application of carbon fiber composite materials on the missile body and engine casing of strategic missiles can greatly reduce the weight and improve the missile's range and assault capability. For example, the three-stage shells of intercontinental missiles developed by the United States in the 1980s are all made of carbon fiber and epoxy resin composite Material.

  The performance of the carbon fiber composite brake prefabricated by Hebei Yuniu Fiberglass Manufacturing Co., Ltd. has reached the international level. Carbon fiber is still the perfect material for modern vehicles such as large civil aircraft, automobiles, and high-speed trains to achieve "lightweight". The demand for carbon fiber in aviation applications is increasing, and the new generation of large civil airliners Airbus A380 and Boeing 787 use about 50% of carbon fiber composite materials. The fuselage of the Boeing 787 is made of carbon fiber, which allows the plane to fly faster and consume less fuel, while increasing cabin humidity for greater passenger comfort.
4. Automotive materials
  Carbon fiber material has also become a material favored by car manufacturers, and has begun to be widely used in car interior and exterior decoration. As an automotive material, the biggest advantage of carbon fiber is its light weight and high strength. Its weight is only 20% to 30% of that of steel, but its hardness is more than 10 times that of steel. Therefore, the use of carbon fiber materials in automobile manufacturing can make a breakthrough in the lightweight of automobiles and bring social benefits of energy saving. The industry believes that the use of carbon fiber in the field of automobile manufacturing will increase.

  Although carbon fiber is light, it has better safety. Although carbon fiber looks like plastic, it is actually more impact-resistant than steel, especially the steering wheel made of carbon fiber has higher mechanical strength and impact resistance. With the cooperation of composite materials, carbon fiber cars have become armored vehicles in family cars.
5. Wind turbine blades
  The rated power of wind turbine generators in the world is getting larger and larger, and the size of the fan blades that are compatible with it is also getting larger and larger. In order to reduce the deformation of the blade, carbon fiber is used in some parts of the main multipliers such as bearings and blades to supplement its stiffness. Carbon fiber also has broad application prospects in new energy fields such as wind energy, nuclear energy and solar energy. When the power of the wind turbine exceeds 3MW and the blade length exceeds 40 meters, the performance of traditional glass fibers has tended to the limit, and the use of carbon fiber composite materials to manufacture blades is a necessary choice. Only carbon fiber can reduce the weight of the blade and meet the requirements of strength and stiffness.
