Strength between PBT and PBT-CF
PBT (Polybutylene Terephthalate) is known for its excellent mechanical properties, including good stiffness and strength, but when reinforced with carbon fiber, such as in PBT-CF, these properties are significantly enhanced. The addition of carbon fiber in PBT-CF improves its tensile strength, flexural strength, and impact resistance, making it more durable and resistant to deformation under high mechanical loads. While PBT performs well under moderate stress, PBT-CF is designed for applications requiring higher stiffness, greater structural integrity, and better wear resistance, making it ideal for more demanding environments where enhanced performance is required.
