Strength between PC and PC-CF
The strength of PC-CF is higher than unreinforced PC due to the addition of carbon fiber, which enhances tensile and flexural strength, stiffness, and dimensional stability. While standard PC is known for its high impact resistance and toughness, it lacks the rigidity needed for structural applications. PC-CF, with carbon fiber reinforcement, significantly improves stiffness and load-bearing capacity while maintaining good impact resistance. However, higher carbon fiber content may slightly reduce ductility compared to pure PC. This makes PC-CF an ideal choice for applications requiring greater strength, wear resistance, and stability under mechanical stress.
