PA66-CF10: Enhanced Performance Carbon Fiber Reinforced Polyamide 66
PA66-CF10 is a high performance polyamide 66 (PA66) composite reinforced with 10% carbon fiber, offering significantly improved strength, stiffness, and dimensional stability over unreinforced PA66. With its higher carbon fiber content, this material delivers elevated mechanical performance while maintaining good processability and excellent thermal resistance. PA66-CF10 is particularly well-suited for structural applications requiring enhanced rigidity, strength, and dimensional consistency over time.
Key Mechanical Properties
Tensile Strength: ≥ 95 MPa
Flexural Strength: ≥ 130 MPa
Notched Impact Strength: ≥ 9 kJ/m²
The 10% carbon fiber reinforcement provides a notable upgrade in mechanical strength and stiffness, while still retaining acceptable impact resistance, making PA66-CF10 suitable for demanding lightweight structural components.
Thermal and Chemical Resistance
PA66-CF10 delivers excellent thermal and chemical resistance, ensuring reliable performance in environments exposed to elevated temperatures and aggressive fluids.
Heat Deflection Temperature (HDT): Approx. 125°C
Long Term Service Temperature: Up to 115°C
Chemical Resistance: Excellent resistance to oils, greases, fuels, and weak acids; moderate resistance to bases; not suitable for strong acids or oxidizing agents
Wear Resistance and Processing
The addition of 10% carbon fiber significantly improves wear resistance and reduces surface friction compared to unreinforced PA66.
Wear Resistance: Enhanced over both standard PA66 and PA66 CF5
Processing Methods: Injection molding, extrusion
Processing Notes: Compatible with standard PA66 processing; minor adjustments may be needed for optimal fiber dispersion and mold fill
Environmental Adaptability
With reduced moisture uptake compared to standard PA66, PA66-CF10 offers excellent dimensional stability across changing environmental conditions.
Water Absorption: Lower than standard PA66
Dimensional Stability: Excellent consistency across temperature and humidity variations
Typical Applications
PA66-CF10 is ideal for structural and semi structural components where higher strength, rigidity, and thermal performance are required without significantly increasing weight. Common applications include:
Automotive Components: Engine bay brackets, structural clips, mounting fixtures
Industrial Equipment: High strength housings, load bearing supports, wear resistant parts
Consumer Electronics: Rigid internal frames, high strength mounts
Mechanical Hardware: Gears, pulleys, bushings, and friction elements

Strength between PA66 and PA66-CF
Compared to unreinforced PA66, PA66-CF (carbon fiber reinforced) offers significantly higher strength and stiffness. The addition of carbon fiber increases tensile and flexural strength, enhances dimensional stability, and reduces deformation under load. While standard PA66 provides good toughness and impact resistance, PA66-CF materials are better suited for structural and high-stress applications where superior mechanical performance is required.
