PEEK-CF10 Material Overview
PEEK-CF10 is a high-performance engineering plastic reinforced with 10% carbon fiber. It is designed for applications where higher strength, dimensional stability, and chemical resistance are required, with increased reinforcement compared to lower carbon fiber grades. The 10% carbon fiber reinforcement improves stiffness, strength, and wear resistance, while retaining the exceptional thermal and chemical properties of pure PEEK.
Mechanical Properties
PEEK-CF10 offers significantly improved mechanical properties compared to pure PEEK, making it suitable for demanding applications that require high load bearing capabilities and resistance to mechanical stress.
Tensile Strength: ≥ 150 MPa
Flexural Strength: ≥ 220 MPa
Impact Strength: ≥ 3.0 kJ/m²
The 10% carbon fiber reinforcement significantly enhances strength and stiffness, making PEEK CF10 ideal for moderate to heavy duty applications.
Thermal and Chemical Resistance
PEEK CF10 retains the excellent thermal and chemical resistance properties of pure PEEK, making it ideal for high temperature environments and exposure to aggressive chemicals. The added carbon fiber reinforcement does not significantly affect these properties, preserving the material’s thermal stability and chemical resistance.
Heat Deflection Temperature (HDT): Approx. 310°C
Long-Term Service Temperature: Up to 270°C
Chemical Resistance: Excellent resistance to a wide range of industrial chemicals, including oils, fuels, and solvents.
PEEK-CF10 performs reliably in environments exposed to high temperatures and aggressive chemicals.
Wear Resistance and Processing Characteristics
The 10% carbon fiber reinforcement in PEEK CF10 significantly enhances its wear resistance, making it suitable for applications where high friction, continuous motion, or long term stress are present. Compared to lower carbon fiber grades, PEEK CF10 offers superior wear resistance.
Wear Resistance: Excellent under high friction and continuous motion
Processing Methods: Suitable for injection molding and extrusion, with processing temperatures higher than those for non reinforced PEEK, but still manageable within typical thermoplastic processing ranges.
PEEK-CF10 offers good processability, making it suitable for a wide range of applications while maintaining durability and wear resistance.
Environmental Adaptability
PEEK CF10 exhibits excellent environmental stability, including low moisture absorption and high dimensional stability, ensuring reliable performance in environments with fluctuating temperatures or humidity levels.
Water Absorption: Low
Dimensional Stability: Excellent, even under varying temperature and humidity conditions
Applications
PEEK CF10 is ideal for applications that require enhanced mechanical strength, high thermal and chemical stability, and superior wear resistance. Typical applications include:
Automotive Industry: Structural parts, housings, and components exposed to high mechanical loads, heat, and chemicals.
Industrial Manufacturing: Components like gears, bearings, bushings, and seals that experience high friction and mechanical stress.
Aerospace: Critical components requiring high strength, heat resistance, and dimensional stability.
Electronics: Housings, connectors, and enclosures exposed to high temperatures and moderate mechanical stresses.
Medical Devices: Components for medical equipment that require biocompatibility, durability, and resistance to sterilization environments.

Strength between PEEK and PEEK-CF
PEEK offers good strength with a tensile strength of around 90-100 MPa, while PEEK-CF (carbon fiber reinforced) has significantly higher tensile strength (100-200 MPa) and flexural strength (150-250 MPa), providing greater stiffness and wear resistance. However, PEEK-CF may have slightly lower impact strength due to its brittleness from the carbon fiber reinforcement.
