PEEK-CF30 Material Overview
PEEK-CF30 is a high performance thermoplastic reinforced with 30% carbon fiber, designed for applications that demand superior strength, enhanced dimensional stability, and increased chemical resistance. The higher carbon fiber content provides a substantial improvement in stiffness, wear resistance, and mechanical strength while preserving the excellent thermal and chemical properties of pure PEEK.
Mechanical Properties
PEEK CF30 provides even more advanced mechanical performance compared to PEEK-CF20 and pure PEEK, making it ideal for applications that require exceptional load bearing capacity and resistance to mechanical stress.
Tensile Strength: ≥ 200 MPa
Flexural Strength: ≥ 300 MPa
Impact Strength: ≥ 4.5 kJ/m²
The 30% carbon fiber reinforcement significantly enhances the material’s strength, stiffness, fatigue resistance, and dimensional stability, making it ideal for extremely demanding environments.
Thermal and Chemical Resistance
PEEK CF30 maintains the outstanding thermal and chemical resistance properties of pure PEEK, allowing it to perform effectively in high temperature and chemically aggressive environments. The increased carbon fiber content does not significantly impact these core properties.
Heat Deflection Temperature (HDT): Approx. 330°C
Long-Term Service Temperature: Up to 280°C
Chemical Resistance: Excellent against oils, fuels, solvents, and aggressive chemicals
PEEK-CF30 excels in environments exposed to extreme temperatures and harsh chemicals, making it ideal for industries where both thermal and chemical resistance are critical.
Wear Resistance and Processing
The 30% carbon fiber reinforcement significantly improves the wear resistance of PEEK CF30, allowing it to withstand high friction and continuous motion better than lower carbon fiber grades. It is particularly suited for applications that require excellent durability and wear life.
Wear Resistance: Superior under high friction and stress
Processing Methods: Suitable for injection molding and extrusion, but requires higher processing temperatures than non reinforced PEEK
PEEK-CF30 maintains excellent processability while providing superior performance in wear resistant applications.
Environmental Adaptability
PEEK CF30 demonstrates exceptional environmental stability, with low moisture absorption and high dimensional stability, ensuring reliable performance across a range of temperature and humidity conditions.
Water Absorption: Very low
Dimensional Stability: Excellent, even under fluctuating temperature and humidity environments
Applications
PEEK-CF30 is ideal for applications that demand high mechanical strength, excellent thermal and chemical stability, and superior wear resistance, such as:
Automotive: Structural components exposed to mechanical loads, heat, and chemicals, requiring high stiffness and durability
Industrial Manufacturing: High performance components like gears, bearings, bushings, and seals subjected to severe wear and stress
Aerospace: Lightweight, high strength components with exceptional heat resistance and dimensional stability for aircraft and spacecraft
Electronics: Durable housings, connectors, and enclosures exposed to high temperatures and mechanical stresses
Medical Devices: Biocompatible components for medical equipment that need 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.
