What is LCF40-PEEK?

High Heat Resistance LCF40-PEEK Composites (high heat resistance 40% long carbon fiber reinforced polyetheretherketone composites) is a high-performance engineering material. 

1. Base materials:
– PEEK matrix: PEEK (polyetheretherketone) is an aromatic semi-crystalline linear thermoplastic polymer. It has a special molecular structure with benzene rings, ether bonds, and carbonyl groups on the molecular chain. This structure endows PEEK with characteristics such as heat resistance, radiation resistance, chemical resistance, and high mechanical strength. Its glass transition temperature is as high as 143°C, the melting point is 343°C, the long-term service temperature is as high as 260°C, and the instantaneous service temperature can reach 300°C.

2. Reinforcements:
– Long carbon fiber (LCF): Long carbon fiber has very high strength and stiffness, which can significantly improve the mechanical properties of materials. In this composite material, the content of carbon fiber is 40%. This proportion setting can not only ensure that the material obtains good reinforcement effects but also maintain the balance of material processing performance and other properties.

3. Performance characteristics:
– Excellent heat resistance: Inheriting the high heat resistance of PEEK itself, and under the reinforcement of long carbon fiber, the heat distortion temperature is further increased. It can maintain good dimensional stability and mechanical properties in high-temperature environments and can be used for a long time under high-temperature working conditions. It is suitable for occasions with extremely high heat resistance requirements, such as aerospace, automotive engine peripheral components, etc.
– Outstanding mechanical properties: The addition of carbon fiber greatly improves the strength, stiffness, and hardness of the material, making it have more excellent mechanical properties than pure PEEK. Its mechanical indicators such as tensile strength and bending strength are significantly improved, and it can withstand greater loads. It is suitable for manufacturing structural parts that bear high stress.
– Good wear resistance: PEEK itself has certain wear resistance, and the reinforcement effect of carbon fiber further improves the wear resistance of the material, making it have a longer service life under friction and wear conditions. It can be used to manufacture wear-resistant parts such as bearings and gears.
– Low friction coefficient: This composite material has a low friction coefficient, which can reduce friction resistance and energy loss when used in moving parts and improve the operating efficiency of equipment.
– Good dimensional stability: The low water absorption and linear thermal expansion coefficient of PEEK and the reinforcement effect of carbon fiber jointly endow this composite material with excellent dimensional stability. Under different temperature and humidity conditions, its dimensional change is extremely small, which can ensure the accuracy and reliability of parts.

4. Application fields:
– Aerospace field: It can be used to manufacture aircraft structural parts, engine parts, wing parts, etc., which can reduce the weight of aircraft and meet the use requirements in harsh environments such as high temperature and high pressure.
– Automobile industry: It is suitable for manufacturing automotive engine parts, transmission system parts, braking system parts, etc., which can improve the performance and reliability of automobiles, reduce the weight of automobiles, and reduce fuel consumption.
– Electronic and electrical field: It can be used to manufacture electronic equipment casings, radiators, connectors, etc. It has good insulation performance and heat resistance and can ensure the safe operation of electronic equipment.
– Mechanical manufacturing field: It can be used to manufacture various mechanical parts such as gears, bearings, bushings, etc., which can improve the service life and operating efficiency of machinery.
