What do T700 and T800 carbon fiber mean?
2 Answers
T-series carbon fibers use the last three or four digits to indicate approximate tensile strength, with units in kgf/mm2 or ksi. Here are the specific details about T700 and T800: T700: T700 is a grade of carbon fiber. The tensile strength of T700 carbon fiber is 4900MPa, with a specific strength of 3060MPa, which is significantly higher than the commonly used T300 but lower than T800. Additionally, the carbon mass fraction in T700-grade carbon fiber is 95.58%, making it a relatively high-performance material. T800: T800 is another grade of carbon fiber, typically measured by tensile strength. The tensile strength of T800 reaches 5.49GPa. T800 carbon fiber is currently the highest-strength grade of carbon fiber that can be industrially mass-produced abroad, playing an irreplaceable role in fields such as aerospace.
I often come across various knowledge about carbon fiber materials. Carbon fiber T700 and T800 represent different strength grades. The larger the number after 'T,' the higher the tensile strength. T700 has a tensile strength of about 4,900 MPa, offering moderate strength, making it suitable for secondary components in cars such as interior trim panels. It helps reduce the vehicle's weight and fuel consumption without sacrificing too much stability. T800, on the other hand, upgrades to approximately 5,880 MPa, providing higher strength and lighter weight, making it more suitable for critical parts like doors or suspension components, enhancing the vehicle's handling response and performance limits. When choosing, cost considerations are essential. T700 is relatively economical and commonly used in regular family cars to reduce weight, while T800 is more often seen in luxury sports cars or race cars, with a significantly higher price. Additionally, in practical applications, special adhesives must be used to prevent delamination. Overall, understanding these grades can help car owners make wiser upgrade decisions and avoid unnecessary expenses.
