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.

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.
