Dry 30% Carbon Fiber (30 CF) PA 6/6
Dry 30 CF PA 6/6 is a grade of PA 6/6. It has the highest strength and lowest ductility compared to the other variants of PA 6/6. The graph bars on the material properties cards below compare dry 30 CF PA 6/6 to: polyamide plastics (top), all thermoplastics (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
