LCF30 PEEK Heat Resistance Composite

LCF30 PEEK is a high-performance thermoplastic composite material made from PEEK (polyether ether ketone) as the matrix and enhanced by 30% long carbon fibers. This material maintains the inherent high-temperature resistance, chemical resistance, and fatigue resistance of PEEK while significantly enhancing its load-bearing capacity, dimensional stability, and long-term structural reliability. It is specifically designed for high-load, harsh conditions and high-integration components.

By combining the inherent heat and chemical resistance of PEEK with the continuous reinforcing network formed by long carbon fibers, LCF30 PEEK becomes an ideal material choice for metal replacement, system weight reduction, and high-reliability structural design.

What is LCF30 PEEK?

LCF30 PEEK is a long carbon fiber reinforced PEEK composite material, mainly used for structural components with high load-bearing capacity and high reliability.
Unlike short-cut fiber-reinforced PEEK, the long carbon fibers form a more complete force transmission structure within the material, which can significantly improve:
Load-bearing capacity
Impact resistance
Fatigue life
Long-term stability of use
This material is suitable for injection molding. It enables the integrated manufacturing of complex structural components while maintaining high mechanical properties and excellent dimensional accuracy.

The Core Advantages of LCF30 PEEK Material

Outstanding mechanical strength
The tensile strength and bending strength of LCF30 PEEK are significantly higher than those of unmodified or short-fiber-reinforced PEEK.
The long carbon fibers can cross the stress concentration areas, effectively inhibiting the generation and expansion of cracks, and are particularly suitable for structural components subjected to cyclic loads.

Excellent high-temperature resistance
LCF30 PEEK can maintain stable mechanical properties at temperatures above 250°C in continuous operation and is suitable for high-temperature, thermal shock, and frequent thermal cycling environments.

Lightweighting
The LCF30 PEEK material can achieve the highest weight reduction effect, reducing system energy consumption and overall load.

Outstanding dimensional stability and creep resistance
The long carbon fiber reinforced structure significantly enhances the creep resistance of the material under long-term stress conditions, ensuring that the components maintain stable dimensions and performance throughout their service life.

Chemical resistance and wear resistance
LCF30 PEEK composite exhibits excellent tolerance to fuel, lubricating oil, hydraulic oil, and various chemical media and is suitable for complex and demanding industrial environments.

Why Choose LCF30 PEEK?

Performance indicator	Unenhanced PEEK	SCF30 PEEK	LCF30 PEEK	Metal materials
Intensity	Low	Ordinary	Moderate to High	Higher
Impact resistance	Good	Improvement, better than unenhanced PEEK	Excellent (fiber bridging effect)

Practical application case

Structural components of the automotive high-temperature transmission system

In modern automobiles and new energy vehicles, components close to the power system are constantly exposed to high temperatures, oil, and continuous mechanical loads. To enhance the overall quality of the vehicle, the customer intends to carry out an upgrade and renovation of the peripheral structural components of the transmission.

The pain points faced by the customer

Problem 1: The metal components are heavy, which can lead to an increase in the overall vehicle weight, thereby affecting fuel efficiency and range.

Problem 2: Insufficient performance in high-temperature environments. Metal parts may experience thermal expansion and corrosion over a long period of time when exposed to the high temperatures of the engine.

Problem 3: High processing costs and heavy inventory pressure. Metal structural components usually require high-precision machining and secondary surface treatment.

To improve these components, the client chose LCF30 PEEK (long carbon fiber 30% reinforced PEEK) as the structural material and achieved the integration of complex geometric functions through injection molding.

Ultimately, it achieved the desired effect of satisfying the customers and effectively resolved their pain points.

Improve the overall lightweight performance of the vehicle
Extend the long-term service life of the load-bearing components
Reduce manufacturing and maintenance costs
Ensure the assembly accuracy and system stability under high-temperature conditions
