We often hear about carbon fiber and it is both familiar and strange to us. It is a kind of high-performance material, which not only has the inherent hardness of carbon materials, but also has the flexible processing characteristics of textile fibers, so carbon fiber is also known as the king of materials.

It is a high-end material often used in airplanes, rockets and bulletproof cars. Among carbon fiber applications, the first is in F1 racing cars in automobile field. Now carbon fiber is also used in civil cars. The cars painted with black paint, and the carbon fiber components with black braided patterns are deliberately exposed. It is eye-catching while driving.

Fiber material is super light and soft. How can it be made into strong automobile parts? How to reduce the cost of expensive carbon fiber used in cars?


Japan and the United States are best at carbon fiber technology. Japan is the largest carbon fiber production country in the century, and Japan's carbon fiber production capacity accounts for half of the world.

In 1880, Edison invented carbon fiber. Yes, it was the Edison who invented the light bulb. Carbon fiber was discovered in the experiment of filament. After more than 100 years of development, BMW used carbon fiber on I3 and I8 in 2010, which opened the application of carbon fiber in automobiles.

Carbon fiber composite is composed of carbon fiber as reinforcement material and resin as matrix material.

Carbon fiber is used in car frame, seat, hood, transmission shaft, rearview mirror and other parts. There are several advantages of carbon fiber for automobile.

• Lightweight: At present, due to the limited battery technology, the short range of battery has become the bottleneck of the development of electric vehicles, which can only be solved from the body structure and material replacement. Carbon fiber composite material is 1/2 lighter than steel and 1/3 lighter than aluminum. The most direct advantages are long range of battery and more energy saving.

• Comfort: The soft tensile property of carbon fiber can improve the noise and vibration control of the whole vehicle, and greatly improve the comfort of the car.

• Reliability: Carbon fiber has higher fatigue strength and better crash energy absorption. It can not only reduce vehicle weight, but also maintain strength and safety, and reduce the safety risk coefficient after lightweight design.

• Improve the service life: Some parts of the vehicle require corrosion resistance and need to be tested under high temperature, low temperature and smoke. Ordinary metal parts can not guarantee the service life in different environments. Carbon fiber has no corrosion and rust problems, which can enhance the service life of automobile parts.
