PEEK-CF20 Material Overview
PEEK-CF20 is a high performance thermoplastic reinforced with 20% carbon fiber, engineered for applications that require superior strength, dimensional stability, and enhanced chemical resistance. The higher carbon fiber content significantly improves stiffness, wear resistance, and mechanical strength while retaining the excellent thermal and chemical properties of pure PEEK.
Mechanical Properties
PEEK-CF20 offers significantly enhanced mechanical performance compared to pure PEEK, making it ideal for demanding applications that require high load bearing capabilities and resistance to mechanical stress.
Tensile Strength: ≥ 180 MPa
Flexural Strength: ≥ 250 MPa
Impact Strength: ≥ 4.0 kJ/m²
The 20% carbon fiber reinforcement boosts the material’s strength, stiffness, and fatigue resistance, making PEEK CF20 suitable for heavy duty applications.
Thermal and Chemical Resistance
PEEK CF20 retains the excellent thermal and chemical resistance properties of pure PEEK, allowing it to perform in high temperature and chemically aggressive environments. The increased carbon fiber content does not significantly alter these properties.
Heat Deflection Temperature (HDT): Approx. 320°C
Long-Term Service Temperature: Up to 280°C
Chemical Resistance: Excellent against oils, fuels, solvents, and aggressive chemicals
PEEK-CF20 excels in harsh environments, including extreme temperatures and exposure to aggressive chemicals.
Wear Resistance and Processing
The 20% carbon fiber reinforcement significantly improves wear resistance, making PEEK CF20 ideal for high friction or continuous motion applications. It outperforms lower carbon fiber grades in terms of durability and wear life.
Wear Resistance: Excellent under high friction and stress
Processing Methods: Suitable for injection molding and extrusion, requiring higher processing temperatures compared to non reinforced PEEK
PEEK-CF20 offers excellent processability while maintaining superior durability.
Environmental Adaptability
PEEK CF20 offers outstanding environmental stability, with low moisture absorption and high dimensional stability, ensuring consistent performance under varying temperature and humidity conditions.
Water Absorption: Very low
Dimensional Stability: Excellent, even in fluctuating temperature and humidity environments
Applications
PEEK-CF20 is ideal for applications that require high mechanical strength, excellent thermal and chemical stability, and superior wear resistance, such as:
Automotive: High strength structural components exposed to mechanical loads, heat, and chemicals
Industrial Manufacturing: Components like gears, bearings, bushings, and seals subjected to high friction and stress
Aerospace: Lightweight, high strength components requiring exceptional heat resistance and dimensional stability
Electronics: Durable housings, connectors, and enclosures exposed to high temperatures
Medical Devices: Biocompatible components for medical equipment requiring durability and resistance to sterilization

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.
