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.
