I. Composition

PEI LCF10 uses polyetherimide as the base material and adds long carbon fibers with a mass percentage of 10% as the filling material for enhanced modification. This combination endows the material with the excellent characteristics of polyetherimide and the high strength of carbon fiber.

II. Performance Characteristics

1. Exceptional strength and rigidity: The incorporation of carbon fiber significantly augments the strength and rigidity of the material. When subjected to various external forces such as tension, compression, and bending, PEI LCF10 exhibits remarkable resistance and can withstand several times its own weight without undergoing deformation.
2. Superior heat resistance: It possesses outstanding heat resistance and can maintain stable performance at relatively high temperatures. Even in an environment reaching up to 200°C, this material can preserve the stability of its physical and chemical properties without softening, deforming, or losing strength.
3. Robust chemical corrosion resistance: It shows good tolerance to a wide range of chemical substances. Whether exposed to acidic, alkaline, or organic solvents, it is highly resistant to erosion. In harsh chemical environments, PEI LCF10 can maintain the integrity of its structure and the stability of its performance.
4. Excellent dimensional stability: Under different temperature and humidity conditions, the dimensional change is minimal. Even after experiencing drastic temperature fluctuations or being in a humid environment for an extended period, the dimensional change rate of this material can be controlled within a very narrow range, ensuring the accuracy and reliability of products.
5. Low friction coefficient: When utilized in moving parts, PEI LCF10 can reduce friction loss and enhance the service life and efficiency of components. Its surface is smooth, resulting in low friction when in contact with other materials, thereby reducing energy consumption.
6. Superior electrical insulation performance: It can play a crucial role in applications that require electrical insulation to ensure the safe operation of equipment. This material has a high resistivity and can effectively prevent the conduction of current and avoid electrical failures.

III. Application Fields

Due to its excellent performance, PEI LCF10 composite material has a wide range of applications in fields such as aerospace, automobile manufacturing, and electronics. For example, in the aerospace field, it can be used to manufacture aircraft parts; in the automobile manufacturing field, it can be used to manufacture high-performance engine parts.

IV. Application Case

It is important to use PEI LCF10 to manufacture the shell of a high-end electronic product. This electronic product has extremely high requirements for the shell. It not only needs to have high strength to resist collisions and drops in daily use but also needs good heat resistance to deal with the heat that may be generated during long-term use.

The PEI LCF10 composite material just meets these requirements. Its high strength and rigidity enable the shell to effectively protect the internal electronic components. Even in the event of an accidental drop, it can minimize the damage to the internal components to the greatest extent. At the same time, good heat resistance ensures that the shell will not deform or be damaged due to the heat generated by the internal electronic components during long-term use.

To verify the performance of this material, manufacturers have conducted a series of strict tests. In the strength test, the shell made of PEI LCF10 composite material is dropped freely from a certain height multiple times. After repeated tests, the shell still remains intact without obvious damage or deformation. In the heat resistance test, the shell is placed in a high-temperature environment for a period of time. After taking it out and observing, the shape and performance of the shell have not changed.

Through this application case, it can be seen that PEI LCF10 composite material provided by Carbon (Xiamen) New Material shows great application potential in the field of high-end electronic products with its excellent performance. With the continuous progress of technology, it is believed that this composite material will be widely used in more fields.

Different carbon fiber reinforced plastics will have differences in performance due to factors such as the difference in matrix resin, the content and type of carbon fiber, and the production process. Specifically, the advantages of PEI+LCF10 still need to be accurately evaluated by comparing and testing with specific other carbon fiber reinforced plastics according to actual application needs. In addition, 10% LCF filled PEI materials produced by different manufacturers may also 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 consult professionals.
