30% Carbon Fiber (30 CF) LCP
30 CF LCP is a grade of LCP. It has the highest strength and lowest ductility compared to the other variants of LCP. The graph bars on the material properties cards below compare 30 CF LCP to: polyester 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.
