I. Introduction to PEI LCF40 Composite Material

(I) Composition

The PEI LCF40 composite material is made by using high-performance polyetherimide as the base material and adding 40% long carbon fibers as the filling material for reinforcement and modification. The high proportion of long carbon fiber filling endows this material with excellent performance.

(II) Performance Characteristics

1. Ultra-high strength: The presence of a large amount of carbon fibers endows PEI LCF40 with extremely high strength and can withstand huge external forces without damage.
2. Outstanding rigidity: The material has very high rigidity and is not easily deformed during use, maintaining a stable structure.
3. Excellent heat resistance: It can work stably in high-temperature environments and has good thermal stability.
4. Superior corrosion resistance: It has strong resistance to various chemical substances and is suitable for various harsh working conditions.
5. Low density advantage: Compared with traditional metal materials, it has a lower density, helping to reduce product weight.
6. Good wear resistance: It performs well in friction environments and extends the service life of products.
7. Prominent electrical insulation: It can be safely applied in fields with high requirements for electrical insulation.

(III) Application Fields

1. Aerospace field: It can be used to manufacture key structural parts of aircraft.
2. Automotive manufacturing field: Suitable for high-performance automotive parts.
3. Electronic and electrical field: It can be used to make high-end electronic equipment casings and the like.

II. Application Case

In the field of automotive manufacturing, a new type of electric racing car uses PEI LCF40 composite material to manufacture the battery case.

This electric racing car pursues extreme performance and lightweight design. Traditional battery cases mostly use metal materials, which are not only heavy but also may be affected by corrosion and collision in complex working environments. The battery case made of PEI LCF40 composite material perfectly solves these problems.

First of all, the ultra-high strength of PEI LCF40 ensures the safety of the battery during high-speed driving and violent collisions of the racing car. Even in extreme cases, it can effectively protect the battery from damage. Its outstanding rigidity makes the casing not deform during installation and use, ensuring the installation accuracy of the battery.

During the manufacturing process, Carbon (Xiamen) New Material Company provides high-quality long carbon fibers, providing a strong guarantee for the performance of the material. After careful design and manufacturing, the weight of this battery case is reduced by 50% compared with the traditional metal case, greatly reducing the overall weight of the racing car and improving the cruising range and acceleration performance.

At the same time, the corrosion resistance of PEI LCF40 composite material enables it to resist the erosion of chemical substances inside the battery and the influence of harsh external environments. Good wear resistance also ensures that the casing will not be damaged due to friction during long-term use. Prominent electrical insulation provides a reliable guarantee for the safe operation of the battery. Through the successful application on this electric racing car, PEI LCF40 composite material brings innovative solutions to the automotive manufacturing field and shows its great potential in the manufacturing of high-performance automotive parts.
