PEEK-CF05 Material Overview

PEEK-CF05 is a high performance engineering plastic that is reinforced with 5% carbon fiber. It is designed for applications where high strength, dimensional stability, and chemical resistance are required, but where a lower reinforcement level is sufficient for moderate mechanical loads and environments. The 5% carbon fiber reinforcement offers improved stiffness, strength, and wear resistance compared to unreinforced PEEK, while still maintaining the excellent thermal and chemical properties inherent to pure PEEK.

Mechanical Properties

PEEK-CF05 offers enhanced mechanical properties compared to pure PEEK, with improvements in strength and stiffness, making it suitable for demanding applications that require good load bearing capabilities without the extreme reinforcement levels seen in higher carbon fiber grades.

Tensile Strength: ≥ 100 MPa

Flexural Strength: ≥ 150 MPa

Impact Strength: ≥ 2.5 kJ/m²

The addition of 5% carbon fiber helps improve the material’s overall mechanical performance, providing moderate stiffness and strength suitable for applications under moderate stress and mechanical loads.

Thermal and Chemical Resistance

PEEK-CF05 retains the outstanding thermal and chemical resistance properties of pure PEEK, making it ideal for use in high temperature environments and exposure to a wide range of chemicals. The 5% carbon fiber content does not significantly affect these properties, preserving PEEK’s natural advantages.

Heat Deflection Temperature (HDT): Approx. 300°C

Long-Term Service Temperature: Up to 260°C

Chemical Resistance: Excellent resistance to a wide range of industrial chemicals, including oils, fuels, and solvents.

The material’s excellent resistance to heat and chemicals makes it highly reliable in environments exposed to aggressive conditions, although not as extreme as higher carbon fiber versions.

Wear Resistance and Processing Characteristics

The 5% carbon fiber reinforcement improves the wear resistance of PEEK-CF05, making it suitable for components that experience moderate friction or stress over time. However, compared to higher fiber content grades, the wear resistance may be less extreme.

Wear Resistance: Good under moderate friction and continuous motion

Processing Methods: Suitable for injection molding and extrusion, with processing temperatures comparable to those of non reinforced PEEK.

PEEK-CF05 offers excellent processability with standard thermoplastic processing methods, while still maintaining superior durability and wear resistance compared to unreinforced PEEK.

Environmental Adaptability

PEEK-CF05 provides excellent environmental stability with 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-CF05 is ideal for applications where moderate reinforcement is sufficient, but superior thermal, chemical, and wear resistance is required. Typical applications include:

Automotive Industry: Lightweight structural parts, housings, and components exposed to moderate mechanical loads, heat, and chemicals.

Industrial Manufacturing: Components like gears, seals, and bushings that experience moderate friction and mechanical load.

Electronics: Housings, connectors, and enclosures exposed to high temperatures and moderate mechanical stresses.

Medical Devices: Components for medical equipment requiring biocompatibility, durability, and resistance to sterilization environments.
