PA66-CF30: Ultra High Strength Carbon Fiber Reinforced Polyamide 66
PA66-CF30 is a premium grade polyamide 66 (PA66) composite reinforced with 30% carbon fiber, offering exceptional strength, stiffness, and dimensional stability well beyond unreinforced or lower filled PA66 materials. The high carbon fiber loading provides maximum mechanical reinforcement while maintaining processability through conventional manufacturing methods. PA66-CF30 is engineered for structural applications that demand high load bearing capacity, superior rigidity, and long term performance in harsh environments.
Key Mechanical Properties
Tensile Strength: ≥ 135 MPa
Flexural Strength: ≥ 190 MPa
Notched Impact Strength: ≥ 11 kJ/m²
The 30% carbon fiber reinforcement delivers a substantial increase in mechanical performance, making PA66-CF30 suitable for highly stressed, lightweight structural components that require top tier rigidity and fatigue resistance.
Thermal and Chemical Resistance
PA66-CF30 provides excellent thermal resistance and chemical compatibility for use in elevated temperature and chemically aggressive conditions.
Heat Deflection Temperature (HDT): Approx. 145°C
Long Term Service Temperature: Up to 130°C
Chemical Resistance: Outstanding resistance to oils, fuels, greases, and weak acids; moderate resistance to bases; not suitable for strong oxidizers or strong acids
Wear Resistance and Processing
The high carbon fiber content gives PA66-CF30 superior wear resistance and reduced surface friction, ideal for dynamic or high load applications involving motion and contact.
Wear Resistance: Maximized over all lower filled PA66 grades
Processing Methods: Injection molding, extrusion
Processing Notes: Requires attention to fiber orientation and mold design; proper screw and barrel wear protection is recommended due to the abrasive nature of carbon fiber
Environmental Adaptability
With minimal water absorption, PA66-CF30 exhibits excellent dimensional control and stability in varying temperature and humidity environments.
Water Absorption: Significantly lower than unreinforced PA66
Dimensional Stability: Outstanding, even under fluctuating ambient conditions
Typical Applications
PA66-CF30 is designed for high performance engineering applications where strength, thermal performance, and dimensional precision are critical. Typical uses include:
Automotive Components: Engine mounts, structural brackets, suspension interface elements
Industrial Equipment: High load housings, machine parts, robotics frames
Aerospace & Defense: Lightweight structural parts with fatigue and vibration resistance
Mechanical Hardware: Precision gear sets, sliding elements, high stress bushings
Sustainability and Design Flexibility
PA66-CF30 enables metal replacement in structural parts, reducing system weight while maintaining high performance. Its excellent processability allows integration into complex designs, offering engineers a material that supports lightweighting, strength optimization, and cost effective production. The durability and long service life of PA66-CF30 also contribute to sustainability through reduced maintenance and part replacement cycles.

Strength between PA66 and PA66-CF
Compared to unreinforced PA66, PA66-CF (carbon fiber reinforced) offers significantly higher strength and stiffness. The addition of carbon fiber increases tensile and flexural strength, enhances dimensional stability, and reduces deformation under load. While standard PA66 provides good toughness and impact resistance, PA66-CF materials are better suited for structural and high-stress applications where superior mechanical performance is required.
