We often hear that the new sports car uses the new cool technologies. Among these new technologies, carbon fiber materials are the most helper. Now the question is: Where is the carbon fiber material? What are the benefits of car carbon fiber? Let's talk about it.
 
The application of carbon fiber in the automotive field has taken the lead in racing cars and has been widely quoted in civilian vehicles in recent years. Painted with varnish, deliberately revealing a deep black woven pattern of carbon fiber components is not just for outstanding looking, the wind of carbon using is getting hot.
 
Carbon fiber is a new type of fiber material with high strength and high modulus fiber with carbon content above 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite crystallites along the axial direction of the fiber and carbonizing and graphitizing. Carbon fiber is “soft outside and hard inside”, its weight is lighter than metal aluminum, but its strength is higher than it, and it has corrosion-resistant and high-modulus properties and is an important material in defense military and civilian use. It not only has the inherent intrinsic properties of carbon materials, but also has the soft processability of textile fibers. It is a new generation of reinforcing fibers.

The density of carbon fiber is generally 1750kg/m3. This low density makes it widely used in large aircraft, such as Airbus A350 and A380. Boeing 787 uses carbon fiber composite to reduce fuel consumption. In addition, the blades of large wind turbines, the body of racing cars and high-end bicycles are all important factors in the increase in demand for carbon fiber composites.

Moreover, carbon fiber has many excellent properties, carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and conductivity between non-metal Between the metal and the metal, the coefficient of thermal expansion is small and anisotropic, the corrosion resistance is good, and the X-ray permeability is good. Good electrical and thermal conductivity, good electromagnetic shielding and so on.
 
Compared with traditional glass fiber, carbon fiber has more than three times the Young's modulus; compared with Kevlar fiber, the Young's modulus is about 2 times, and it is insoluble in organic solvents, acids and alkalis. Excellent corrosion resistance.
