With the requirements of energy conservation, emission reduction, and lightweight development of automobiles, the advantages of carbon fiber composite materials in automotive components are gradually emerging. At present, carbon fiber composite materials are becoming increasingly common in the production of automotive components, such as brake pads, transmission shafts, body shells, fuel tanks, battery boxes, etc.
Given the development trend of the automotive industry, carbon fiber composite materials will have broad application prospects in automotive components. This article will briefly explain some application advantages of carbon fiber.
1. Carbon fiber car battery box
The power battery is an important power component of new energy vehicles, and the battery box, as a carrier for protecting the battery, is generally installed under the car to protect the lithium battery from external erosion and damage. The traditional battery casing is made of metal material, which increases the weight of new energy vehicles and reduces their range. Carbon fiber composite material is lightweight and high-strength, and its lightweight effect is significant when used to make automotive battery cases. Taking the carbon fiber car battery case customized by a certain car brand in Bozhi as an example, compared with the original metal material case, the quality has been reduced by 60%, which has a good improvement effect on reducing car energy consumption and increasing endurance. The excellent properties of carbon fiber composites, such as corrosion resistance, low creep and aging resistance, also play a good role in the protection of batteries.
2. Carbon fiber car seats
The internal bracket structures of car seats we encounter in daily life are mostly steel structures, which are relatively bulky in quality. The internal shock absorbers are mostly springs, which are prone to rust over time, greatly reducing the shock absorption effect and causing a lot of resource waste. The carbon fiber composite seat frame has performance advantages such as 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 higher safety factor.
3. Carbon fiber rearview mirror housing
Carbon fiber composite materials can also be used to make rearview mirror shells for cars, but lightweight significance is not significant. The main purpose is to meet customers' needs for carbon fiber car products and play an aesthetic role. Similar components include carbon fiber car license plate frames, carbon fiber car interior parts, etc.
4. Carbon fiber anti-collision beam and energy absorbing box
The collision beam and energy absorbing box are the main components of the bumper system that absorb energy during a collision. Traditional collision beams and energy absorbing boxes are generally made of metal materials such as steel and aluminum, which to some extent limits the lightweight level of vehicles. Carbon fiber composite materials have a very high energy absorption rate when facing impact, even more than four times higher than materials such as steel and aluminum. Therefore, they are very suitable for use in parts of cars that are prone to impact, such as front collision beams and energy absorbing boxes. Using carbon fiber materials to make car energy absorbing boxes not only reduces the weight of components by 60% -80% compared to raw metal materials, but also makes elastic deformation the main deformation form under low-speed collisions, increasing energy absorption rate.
The above are all application cases of carbon fiber products in the automotive field. We have also customized these carbon fiber automotive parts for enterprises and car owners multiple times. We have more than ten years of customized experience in the field of carbon fiber, and have complete molding and processing equipment, which can complete the production of various types of carbon fiber products.
