PA6-LCF10 Long Carbon Fiber Reinforced Nylon Composite Material:

PA6-LCF10 is a nylon 6 composite material reinforced with 10% long carbon fibers. Utilizing specialized processing technology, continuous carbon fibers are uniformly dispersed within the nylon matrix. This innovative material retains the excellent wear resistance and processing characteristics of nylon 6 while significantly enhancing mechanical strength and dimensional stability through carbon fiber reinforcement, making it an ideal metal replacement solution for industrial applications.

Key Characteristics

1. Enhanced Mechanical Performance

The incorporation of long carbon fibers elevates the material’s tensile strength to over 180 MPa and flexural modulus to exceeding 8 GPa. Compared to standard nylon 6, its creep resistance improves by approximately 5 times, making it particularly suitable for components under sustained loads. Even at 80°C, it retains over 85% of its room-temperature strength.

2. Exceptional Lightweighting Effect

With a density of just 1.3 g/cm³, PA6-LCF10 is over 50% lighter than aluminum alloys. For example, when used in automotive engine brackets, it achieves 40% weight reduction while meeting all strength requirements.

3. Superior Fatigue Resistance

In cyclic load testing, PA6-LCF10 maintains 90% of its original strength after 1 million stress cycles—far surpassing short-fiber reinforced nylon (typically 60-70%). This property makes it ideal for moving parts and dynamic applications.

4. Excellent Dimensional Stability

• Heat deflection temperature (1.82 MPa load): 210°C

• Linear thermal expansion coefficient: as low as 2×10⁻⁵/°C

• Minimal dimensional variation across temperature/humidity changes, ensuring precision within ±0.1 mm/m.

5. Processing Adaptability

Compatible with injection molding and extrusion, featuring:

• Low molding shrinkage (0.3-0.5%) – 50% reduction vs. standard nylon

• Capability to produce complex structures with wall thickness ≥1.5 mm

Typical Industrial Application Example

Textile Machinery Yarn Guide Components:

In high-speed textile machinery, traditional metal yarn guides face challenges such as excessive weight and high energy consumption. PA6-LCF10 yarn guides demonstrate remarkable advantages:

• 55% weight reduction, significantly lowering equipment energy consumption

• Wear-resistant lifespan extended to 8,000 hours – 3 times longer than metal components

• 15 dB reduction in operational noise

• Eliminates yarn abrasion caused by metal parts
