I. Introduction to PEI LCF30 composite material

(I) Composition

The PEI LCF30 composite material is made by using high-performance polyetherimide as the base material and adding 30% long carbon fibers as the filling material for reinforcement and modification. The addition of long carbon fibers significantly enhances the performance of the material.

(II) Performance characteristics

1. High strength: Due to the reinforcement of carbon fibers, PEI LCF30 has extremely high strength and can withstand large external forces without being damaged.
2. High rigidity: The material has high rigidity and is not easily deformed, and can maintain a stable shape during use.
3. Good heat resistance: It can be used at relatively high temperatures and has excellent thermal stability.
4. Excellent corrosion resistance: It has good resistance to various chemical substances and is suitable for various harsh environments.
5. Low density: Compared with traditional metal materials, PEI LCF30 has a lower density, which helps reduce the weight of products.
6. Good wear resistance: It performs well in friction environments and can extend the service life of products.
7. Outstanding electrical insulation: It can be applied in fields with high requirements for electrical insulation performance.

(III) Application fields

1. Aerospace field: It can be used to manufacture aircraft parts such as wings and fuselage structural parts.
2. Automotive manufacturing: It is used for automotive engine parts and body structural parts, which can reduce vehicle weight and improve fuel efficiency.
3. Electronic and electrical field: It is used to make high-performance electronic equipment casings and radiators.

II. Application case

In the field of automotive manufacturing, a new type of high-performance sports car uses PEI LCF30 composite material to manufacture the engine intake manifold.

This sports car aims at extreme performance and lightweight design. Traditional intake manifolds usually use metal materials, which are heavy and prone to corrosion and deformation under high temperature and high pressure working environments. The intake manifold made of PEI LCF30 composite material fully exploits the excellent performance of this material.

First of all, the high strength and high rigidity of PEI LCF30 ensure the stability of the intake manifold under high engine speed and high load. It can withstand strong air flow impacts and pressure fluctuations without cracking or deformation. Secondly, the good heat resistance of this material enables it to work normally in the high-temperature environment of the engine compartment without softening or losing strength due to temperature increase.

During the manufacturing process, Carbon (Xiamen) New Material Company provides high-quality long carbon fibers to ensure the stable performance of the composite material. After precise design and manufacturing, the weight of this intake manifold is reduced by 40% compared with the traditional metal intake manifold, greatly reducing the overall weight of the vehicle and improving fuel efficiency and acceleration performance. At the same time, the corrosion resistance of PEI LCF30 composite material also enables the intake manifold to resist the erosion of various chemical substances emitted by the engine and prolongs the service life.

In addition, its low-density characteristic further helps the sports car achieve lightweight design. Good wear resistance ensures that the intake manifold will not be damaged due to friction during long-term use. Outstanding electrical insulation also provides a safer working environment for the engine’s electronic control system. Through the successful application on this sports car, PEI LCF30 composite material provides a high-performance and lightweight solution for the automotive manufacturing industry and is expected to be more widely used in the future.

Different carbon fiber reinforced and modified thermoplastic composite raw materials will have differences in performance due to factors such as different matrix resins, carbon fiber content and types, and production processes. The advantages of specific composites still need to be accurately evaluated according to actual application needs and through comparative tests with specific other carbon fiber reinforced plastics. In addition, thermoplastic composites produced by different manufacturers may have different emphases and variations in performance. If more accurate and detailed information is needed, it is recommended to refer to the product manuals and technical data sheets of relevant manufacturers or contact us directly.
