Strength between PP and PP-CF
PP-CF exhibits significantly higher strength and stiffness compared to unreinforced PP due to the addition of carbon fiber reinforcement. While standard polypropylene (PP) is known for its flexibility and impact resistance, it lacks the rigidity and load bearing capacity required for high-performance applications. In contrast, PP-CF enhances tensile strength, flexural modulus, and dimensional stability, making it more resistant to deformation under mechanical stress. This improved performance allows PP-CF to be used in applications where higher strength-to-weight ratio and structural integrity are critical.
