Mechanical Properties
PA6-LCF10 is a high performance polyamide 6 (PA6) composite reinforced with 10% long carbon fiber (LCF), providing a significant upgrade in strength, stiffness, and impact resistance over unreinforced or short fiber PA6. The long carbon fibers enable superior load distribution and durability, making PA6-LCF10 an excellent candidate for lightweight structural applications that demand mechanical integrity and fatigue resistance.
Tensile Strength: ≥ 100 MPa
Flexural Strength: ≥ 145 MPa
Impact Strength: ≥ 10 kJ/m²
The 10% long carbon fiber reinforcement enhances the balance of stiffness, toughness, and dimensional control, particularly valuable in components subject to vibration, shock, or repeated load.
Thermal and Chemical Resistance
PA6-LCF10 maintains robust thermal stability and chemical resistance, even in aggressive operating environments.
Heat Deflection Temperature (HDT): Approx. 130°C
Long Term Service Temperature: Up to 120°C
Chemical Resistance: Excellent against oils, greases, fuels, and weak acids; moderate resistance to alkalis; not recommended for strong acids or oxidizers
Its thermal and chemical profile supports reliability in demanding automotive and industrial systems.
Wear Resistance and Processing
The use of long carbon fibers improves both surface wear resistance and long term fatigue life compared to PA6-CF10 and unfilled PA6.
Wear Resistance: Enhanced over PA6 and short CF grades
Processing Methods: Injection molding (with LCF compatible feeders), compression molding
Processing Notes: Optimized low shear conditions are important to preserve fiber length and distribute fibers uniformly for maximum mechanical benefit.
Environmental Adaptability
With lower water absorption than unreinforced PA6, PA6-LCF10 ensures greater dimensional precision and stable mechanical behavior across variable environmental conditions.
Water Absorption: Reduced compared to standard PA6
Dimensional Stability: Strongly improved due to low moisture uptake and reinforcing long fiber matrix
Applications
PA6-LCF10 is engineered for semi structural to structural parts that demand a combination of lightweight design, strength, and long term durability under stress or motion. Common applications include:
Load bearing brackets and semi structural reinforcements
Lightweight engine bay components
Interior, exterior structural mounts

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.
