What’s PEEK LCF40?

PEEK LCF40 composite material is a thermoplastic composite material with excellent performance.

Here are its main characteristics:

1. Unique composition

This material uses Polyetheretherketone (PEEK) as the base material and is filled with 40% long carbon fibers. PEEK itself has high temperature stability, while carbon fiber is known for its excellent strength. The combination of the two endows the material with excellent performance in high temperature and high strength environments.

2. Excellent performance characteristics

– Excellent mechanical strength: It can withstand large external forces without being easily damaged and shows strong resistance when subjected to various stresses such as tension, compression, and bending.
– Good chemical corrosion resistance: It can maintain stable performance under the erosion of various chemical substances. Whether in acidic, alkaline or organic solvent environments, it can maintain the integrity of its structure and performance.
– Strong stability at high temperatures: Even in high temperature environments, it can maintain the stability of its structure and performance without softening, deforming or losing strength due to high temperatures.
– Low friction coefficient: When used in moving parts, it can reduce friction loss and improve the service life and efficiency of parts.
– Good insulation performance: It can play an important role in occasions that require electrical insulation to ensure the safe operation of equipment.
– High dimensional stability: Under different temperature and humidity conditions, the dimensional change is extremely small, ensuring the accuracy and reliability of parts.
– Good flame retardancy: When encountering a fire source, it has a certain self-extinguishing ability to reduce the risk of fire.

3. Wide range of application fields

These characteristics make PEEK resins wtih 40% LCF filled widely used in fields such as aerospace, the automotive industry, and high-performance sports equipment.

PEEK LCF40 Applied in Brake System

Carbon (Xiamen) New Material compounds PEEK LCF40 composite material for producing brake system components.

Requirements of extreme working environments

These brake system components are in an extremely extreme working environment and need to maintain stability and high strength under high temperature, high pressure and high friction conditions. During the high-speed driving of a racing car, the brake system will generate extremely high temperatures in a short period of time, even reaching several hundred degrees. At the same time, the pressure borne by braking is also huge and needs to be able to withstand strong braking forces instantly. Moreover, due to the high-speed movement of the racing car, the friction coefficient between the brake component and the brake disc is also very high. Under such extreme conditions, traditional materials are often difficult to be competent and are prone to deformation, wear and even failure.

Advantageous performance

The high heat resistance of the PEEK+LCF40 material makes the brake system not easily deformed during violent braking. It can maintain a stable structure in a high temperature environment and ensure the reliability of the brake system. At the same time, the addition of long carbon fibers significantly improves the strength and rigidity of the components. Carbon fiber has extremely high strength and rigidity and can withstand huge pressures and impacts. During braking, the brake component needs to withstand strong braking forces, and the carbon fiber in the PEEK 40%LCF composite material can effectively disperse these forces, ensuring the high efficiency and durability of the brake system.

Powerful proof of test data

Test data shows that at a high temperature of 600°C, the strength attenuation of this material is less than 5%, while that of traditional materials is as high as 15%. This data fully proves the superior performance of the PEEK LCF40% composite material in high temperature environments. In addition, after multiple tests simulating the actual braking situation of racing cars, the brake components made of PEEK LCF40 composite material have shown excellent wear resistance and stability, greatly prolonging the service life of the brake system.

Value manifestation of application cases

This application case shows the superior performance of 40%LCF PEEK composite material under extreme working conditions and further verifies its potential in high-performance components. It provides a powerful guarantee for the safety performance of high-performance racing cars and also provides a reliable material selection scheme for other fields when facing extreme working conditions.
