The friction coefficient of PA66-CF is significantly lower than that of unreinforced PA66, thanks to the presence of carbon fiber, which acts as a solid lubricant. While PA66 already offers decent wear resistance, the addition of carbon fiber greatly enhances its tribological performance by reducing surface friction and improving wear resistance under load and repeated motion. This makes PA66-CF especially suitable for applications involving sliding contact or dynamic mechanical stress.

PA66-LCF10 Reinforced for Auto Electronics – High-Performance Engineering Plastic
Introduction to PA66-LCF10
PA66-LCF10 is a high-performance engineering thermoplastic composite made from Polyamide 66 (PA66) reinforced with 10% long carbon fiber (LCF). This advanced material combines the excellent mechanical properties of PA66 with the superior strength and stiffness provided by carbon fiber reinforcement. The result is a lightweight yet incredibly durable material that excels in demanding industrial applications, particularly in the automotive and electronics sectors.
PA66 itself is known for its high melting point, chemical resistance, and toughness, making it a popular choice for engineering applications. The addition of long carbon fibers enhances its structural integrity, offering improved tensile strength, impact resistance, and dimensional stability—key factors for components subjected to high stress and thermal cycling.
Key Properties of PA66-LCF10
-
High Strength & Stiffness
The 10% long carbon fiber reinforcement significantly increases the material’s tensile strength and rigidity, making it ideal for load-bearing automotive parts. -
Excellent Heat Resistance
PA66-LCF10 maintains its mechanical properties at elevated temperatures, with a heat deflection temperature (HDT) of approximately 250°C, ensuring reliability in high-heat environments like engine compartments. -
Low Warpage & Dimensional Stability
Unlike short-fiber composites, long carbon fibers provide better resistance to warping, ensuring tight tolerances for precision components. -
Lightweight Yet Durable
Carbon fiber reinforcement reduces weight while enhancing durability, making it a superior alternative to metals in automotive applications. -
Chemical & Wear Resistance
PA66-LCF10 resists oils, fuels, and other automotive fluids, reducing degradation over time.

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.
