Strength Comparsion PA6 and PA6-CF
PA6-CF, reinforced with carbon fiber, exhibits significantly higher strength and stiffness compared to unfilled PA6. While standard PA6 offers good toughness and moderate mechanical properties, the addition of carbon fiber enhances tensile and flexural strength, improving load-bearing capacity and dimensional stability. PA6-CF also has lower creep and reduced thermal expansion, making it more suitable for high performance applications where strength and rigidity are critical. However, PA6 retains better elongation and impact resistance, making it more flexible and less brittle under sudden loads.
