Carbon fiber composites have been used in automobile manufacturing for a period of time. Carbon fiber composites can be seen in professional racing cars to household cars. However, due to the cost and recycling technology of carbon fiber, carbon fiber composites have not been widely used in the automotive market. At present, the following types of carbon fiber automotive parts can be mass produced.
1. Carbon fiber car battery box
Power battery is an important power component of new energy vehicles. The battery box is generally installed in the lower part of the vehicle as a load-bearing part to protect the battery and lithium battery from external corrosion and damage. Traditional battery boxes are made of metal materials, which will increase the weight of new energy vehicles and reduce their service life. The carbon fiber composite is light in weight and high in strength. It can be used to make automobile battery box and has obvious lightweight effect. Take the carbon fiber car battery box customized by Bosch for an automobile brand as an example. Compared with the original metal shell, the weight is reduced by 60%, which has a good effect on reducing the energy consumption and increasing the durability of the car. The excellent properties of carbon fiber composites, such as corrosion resistance, low creep and aging resistance, also play a very good role in battery protection.
2. Carbon fiber car seats
In our life, the internal support structure of car seats is mainly steel structure, which is relatively heavy and bulky. Most of the internal shock absorbers are springs. With the passage of time, the spring is easy to rust, and the damping effect will be greatly reduced. At the same time, it will cause a lot of waste of resources. Carbon fiber composite seat frame has the advantages of impact resistance, corrosion resistance, high strength and fatigue resistance. It can not only fully meet the requirements of complex working conditions, but also has a high safety factor.
3. Carbon fiber rear view mirror shell
Carbon fiber composites can also be used to manufacture automobile rearview mirror housing, but it is of little significance to reduce the weight. It is mainly to meet customer demand for carbon fiber automotive products and play a beautiful role. Similar components include a carbon fiber license plate frame, Carbon fiber automotive interior parts, etc
4. Carbon fiber anti-collision beam energy absorbing box
Anti collision beam and energy absorption box are the main components of bumper system, which absorb energy in the process of collision. Traditional crash beams and energy absorbing boxes are usually made of metal materials, such as steel and aluminum. This limits the brightness of the vehicle to a certain extent. Quantitative level. Carbon fiber composite has a very high energy absorption rate in impact, even more than 4 times higher than steel, aluminum and other materials, so it is very suitable for collision prone parts such as automobile, such as front impact beam and energy absorption box. Using carbon fiber material to make automobile energy absorbing box not only reduces the mass of parts by 60% - 80% compared with the original metal material, but also makes elastic deformation become the main form of deformation in low-speed collision, thus increasing the energy absorption rate.
With the continuous maturity of carbon fiber customization technology, carbon fiber composites will account for more and more proportion in the overall structure of the car, which has a very positive effect on the lightweight of the car and meets the overall demand of sustainable development.
