PEEK-LCF10 Material Overview
PEEK-LCF10 is a high performance thermoplastic reinforced with 10% long carbon fiber, designed for applications that require good mechanical strength, dimensional stability, and chemical resistance. The moderate long carbon fiber content enhances stiffness and wear resistance, while still retaining the excellent thermal and chemical properties of pure PEEK.
Mechanical Properties
PEEK-LCF10 offers good mechanical performance suitable for a variety of applications that demand moderate strength and wear resistance but do not require the extreme load bearing capacities seen in higher long carbon fiber grades.
Tensile Strength: ≥ 200 MPa
Flexural Strength: ≥ 350 MPa
Impact Strength: ≥ 3.0 kJ/m²
With 10% long carbon fiber reinforcement, PEEK LCF10 provides improved stiffness, fatigue resistance, and dimensional stability compared to pure PEEK, making it suitable for moderate stress environments.
Thermal and Chemical Resistance
PEEK LCF10 retains the excellent thermal and chemical resistance properties of pure PEEK, performing reliably under a wide range of temperatures and chemical exposures. The carbon fiber content has minimal impact on these key characteristics.
Heat Deflection Temperature (HDT): Approx. 330°C
Long-Term Service Temperature: Up to 250°C
Chemical Resistance: Excellent against oils, fuels, solvents, and aggressive chemicals
PEEK LCF10 is well suited for industrial and automotive applications where thermal and chemical resistance are critical.
Wear Resistance and Processing
The 10% carbon fiber reinforcement enhances wear resistance while still allowing for easier processing compared to higher carbon fiber grades.
Wear Resistance: Good under moderate friction and stress
Processing Methods: Suitable for injection molding and extrusion at temperatures lower than higher reinforced PEEK grades
PEEK-LCF10 offers good processability while providing enhanced durability compared to pure PEEK in applications subject to wear.
Environmental Adaptability
PEEK LCF10 exhibits low moisture absorption and good dimensional stability, ensuring consistent performance under fluctuating temperature and humidity conditions.
Water Absorption: Low
Dimensional Stability: Excellent, even under varying temperature and humidity environments
Applications
PEEK LCF10 is ideal for applications where moderate mechanical strength, thermal stability, and wear resistance are needed, including:
Automotive: Components exposed to moderate mechanical loads and temperatures
Industrial Manufacturing: Wear resistant components like seals, bushings, and gaskets
Aerospace: Lightweight, strong components for moderate stress applications
Electronics: Durable enclosures and connectors exposed to moderate mechanical stresses
Medical Devices: Components requiring good durability and resistance to sterilization processes
