Mechanical Properties
PA6-LCF40 is an ultra-high performance polyamide 6 (PA6) composite reinforced with 40% long carbon fiber (LCF), delivering outstanding mechanical strength, stiffness, and fatigue resistance. The elevated LCF content enables exceptional load-bearing capacity and structural integrity under severe dynamic and thermal conditions.
Tensile Strength: ≥ 160 MPa
Flexural Strength: ≥ 240 MPa
Impact Strength: ≥ 14 kJ/m²
PA6-LCF40 achieves a highly optimized balance between extreme rigidity and impact durability, making it ideal for structural applications exposed to continuous vibration, mechanical shock, or long-term load.
Thermal and Chemical Resistance
PA6-LCF40 provides excellent high temperature performance and long term dimensional stability under chemically aggressive operating conditions.
Heat Deflection Temperature (HDT): Approx. 150°C
Long Term Service Temperature: Up to 135°C
Chemical Resistance: Excellent resistance to oils, greases, fuels, and weak acids; moderate resistance to alkalis; not suitable for strong acids or oxidizing agents
Its superior thermal resistance and chemical profile make it well suited for demanding industrial and under the hood automotive environments.
Wear Resistance and Processing
The 40% LCF reinforcement delivers exceptional wear resistance, low creep, and superior surface durability under continuous load and frictional conditions.
Wear Resistance: Extremely high – designed for severe wear or load cycling
Processing Methods: Injection molding (with specialized LCF feeders), compression molding
Processing Notes: Use low shear settings to maintain fiber integrity; hardened tools are required due to abrasive filler content
Environmental Adaptability
PA6-LCF40 maintains structural precision across a wide range of environmental conditions thanks to its reduced moisture uptake and superior dimensional control.
Water Absorption: Significantly lower than unreinforced PA6
Dimensional Stability: Exceptional – remains stable under high humidity and thermal fluctuation
Applications
PA6-LCF40 is engineered for high performance structural components requiring extreme mechanical and environmental durability. Key sectors include:
Automotive:
Chassis and drivetrain support structures
Under hood load bearing brackets and mountings
Lightweight replacements for aluminum or steel components
Industrial:
Structural machine frames and support arms
Robotic linkages and dynamic assemblies
High load enclosures and 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.
