Mechanical Properties
PA6-CF20 is a high performance polyamide 6 (PA6) composite reinforced with 20% carbon fiber, offering significantly enhanced stiffness, strength, and dimensional stability compared to unreinforced PA6. The increased carbon fiber content improves durability, reduces creep, and minimizes deformation under load, making it well suited for demanding structural applications. It also exhibits superior fatigue resistance, ensuring long term performance in dynamic or high-stress environments.
Key Mechanical Properties
Tensile Strength: ≥ 120 MPa
Flexural Strength: ≥ 160 MPa
Notched Impact Strength: ≥ 10 kJ/m²
With a 20% carbon fiber reinforcement, PA6-CF20 achieves an optimal balance of mechanical strength, rigidity, and weight reduction, making it an ideal material for high performance industrial and automotive applications.
Thermal and Chemical Resistance
PA6-CF20 offers excellent thermal stability and chemical resistance, allowing it to withstand harsh environments.
Heat Deflection Temperature (HDT): Approx. 140°C
Long Term Service Temperature: Up to 130°C
Chemical Resistance: Excellent resistance to oils, lubricants, and weak acids, but sensitive to strong acids and bases
This material ensures long term stability in environments requiring resistance to heat and chemical exposure.
Wear Resistance and Processing
The 20% carbon fiber reinforcement significantly enhances wear resistance and reduces friction compared to standard PA6.
Wear Resistance: Highly improved over unreinforced PA6
Processing Methods: Injection molding, extrusion
Due to the higher carbon fiber content, optimized processing conditions and reinforced tooling are recommended to achieve the best results.
Environmental Adaptability
PA6-CF20 absorbs less moisture than unfilled PA6, resulting in improved dimensional stability and mechanical performance in humid or fluctuating environments.
Water Absorption: Lower than standard PA6, reducing swelling and mechanical degradation
Dimensional Stability: Greatly improved, ensuring consistent performance in varying conditions
These properties make PA6-CF20 a reliable choice for precision components exposed to humidity and temperature variations.
Typical Applications
PA6-CF20 is ideal for high performance industrial and automotive applications that require superior strength, rigidity, and lightweight characteristics. Common applications include:
Structural Components: Load bearing brackets, frames, and support structures
Automotive Parts: High strength brackets, housings, dashboard structures
Sports Equipment: High impact, self lubricating performance components
Mechanical Engineering: Gears, sliding rails, and bearing housings

Strength Comparsion PA6 and PA6-CF
PA6-CF, reinforced with carbon fiber, exhibits significantly higher strength and stiffness compared to unfilled PA6. While standard PA6 offers good toughness and moderate mechanical properties, the addition of carbon fiber enhances tensile and flexural strength, improving load-bearing capacity and dimensional stability. PA6-CF also has lower creep and reduced thermal expansion, making it more suitable for high performance applications where strength and rigidity are critical. However, PA6 retains better elongation and impact resistance, making it more flexible and less brittle under sudden loads.
