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.

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.

  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.

  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.
