Carbon Fiber Reinforced Nylon — High-Strength FDM and CNC Material

Last updated: April 21, 2026

Carbon fiber reinforced nylon (CF-Nylon) is a high-performance composite material where short carbon fibers (typically 10-30% by weight) are compounded into a nylon matrix. This reinforcement dramatically improves mechanical properties, making CF-Nylon one of the strongest engineering materials available for both 3D printing and CNC machining applications.

CF-Nylon Material Properties

With tensile strength up to 120 MPa for CF30 grades (vs 80 MPa for unfilled nylon 66) and flexural modulus of 15,000-18,000 MPa (approaching aluminum stiffness), CF-Nylon offers exceptional performance. The coefficient of thermal expansion is 70% lower than unfilled nylon, ensuring dimensional stability. Our PA6-CFフィラメント provides excellent strength-to-weight ratio.

3D Printing vs CNC Machining

For 3D printing, CF-Nylon offers rapid prototyping and complex geometries but requires hardened steel or ruby nozzle (brass wears rapidly). CNC machining provides consistent properties and tighter tolerances (±0.02mm). For CNC applications, our PA66-CF30 stock material is recommended.

アプリケーション

CF-Nylon is used in aerospace for UAV frames, satellite components, and interior brackets. Automotive applications include engine mounts, structural components, and lightweight replacements. Industrial uses include pump impellers, bearing surfaces, and wear components.

Carbon Fiber Nylon — Frequently Asked Questions

Why does carbon fiber wear out brass nozzles quickly?

Carbon fiber has hardness of approximately 200 HB (Brinell), while standard brass has hardness of only 55-100 HB. A brass nozzle will wear out within 10-50 hours of printing with CF filament. Highly filled CF30 can destroy brass within 10 hours. Always use hardened steel or ruby nozzles.

Is CF-Nylon stronger than aluminum?

CF-Nylon PA66+CF30 has tensile strength up to 120 MPa with specific strength comparable to 6061-T6 aluminum at approximately 60% of the weight. Carbon fiber reinforcement reduces thermal expansion by 70% vs unfilled nylon.
