Get to Know PEEK LCF5

PEEK LCF5 is a kind of composite material. It is a combination of polyetheretherketone (PEEK) as the base and approximately 5% long carbon fibers added.

Polyetheretherketone (PEEK) is a linear aromatic polymer material that inherently possesses outstanding properties. It has high mechanical strength, good dimensional stability, excellent corrosion resistance, remarkable high-temperature resistance, and self-lubricating characteristics. Carbon fiber is a fiber material with high strength and high modulus and has a good reinforcing effect.

The PEEK LCF5 composite material formed by adding carbon fibers to PEEK integrates the advantages of PEEK and carbon fibers. On the one hand, the addition of carbon fibers notably enhances the strength, rigidity, and wear resistance of PEEK, enabling it to better endure larger loads and abrasion. On the other hand, the PEEK matrix provides good support and protection for carbon fibers, allowing them to fully exert their reinforcing function. At the same time, it also retains the advantages of PEEK itself, such as corrosion resistance and high-temperature resistance.

Generally speaking, the carbon fiber content in PEEK-LCF5 is about 5%. However, under different manufacturers or application scenarios, the carbon fiber content may vary to a certain extent. If the carbon fiber content is too high, it may lead to a significant increase in the processing difficulty of the material, and even problems such as equipment damage may occur during the processing. If the carbon fiber content is too low, the reinforcing effect of carbon fiber on PEEK material cannot be fully exerted. Therefore, in actual production, the appropriate carbon fiber content needs to be determined according to specific performance requirements and processing technologies.

Application Scenarios

The performance requirements for materials are extremely demanding. Surgical robots need to perform high-precision and high-frequency operations in a complex medical environment, and their various joint parts bear huge pressure and frequent movements in the field of high-end medical equipment, especially in some advanced surgical robots.

Under such high-intensity usage conditions, traditional materials often have many problems. For example, ordinary engineering plastics may experience wear after long-term use, leading to unsmooth joint movement and affecting the precision of surgery; although metal materials have high strength, they have disadvantages such as large weight and easy corrosion, and may also interfere with the electromagnetic environment of certain medical equipment.

PEEK-LCF5, on the other hand, shows unique advantages in this field. It contains about 5% long carbon fibers, which significantly improves the mechanical properties such as tensile strength, bending strength, and modulus of the material. In the key joint connection parts of surgical robots, PEEK+LCF5 can easily withstand frequent movements and large loads. For example, during minimally invasive surgeries, the joints of surgical robots need to rotate at multiple angles and be precisely positioned. Components made of PEEK LCF5 can ensure dimensional stability and high precision during these complex movements.

In terms of details, this material has a high surface smoothness, reducing frictional resistance and making the movement of joints more smooth. At the same time, it has good thermal stability and will not deform due to the heating of equipment during surgery. In addition, PEEK LCF 5 also has good chemical corrosion resistance and can resist the erosion of various disinfectants and body fluids in the medical environment.

Taking a high-precision minimally invasive surgical robot as an example, its arm joint part adopts LCF5-PEEK material. In actual surgeries, doctors can precisely control the movements of the robot through the console, and the joint parts of the robot can still maintain stable performance under the action of various forces. Even after long-term complex operations, these parts will not show obvious deformation or damage, ensuring the reliability and stability of the surgical robot. This provides doctors with accurate operation support, greatly improving the success rate and safety of surgeries and bringing better treatment effects to patients.
