Carbon fiber materials are widely used in many fields such as aerospace, automobile manufacturing, sports equipment, etc. Among them, T700 and T800 are two common types of carbon fiber materials, which have some differences in performance and application.
Firstly, from the perspective of performance parameters, the main difference between T700 and T800 lies in their strength and modulus. T800 has a higher strength, reaching 4900Mpa, while the strength of T700 is 4400Mpa. At the same time, the modulus of T800 is also higher, reaching 294Gpa, while the modulus of T700 is 230Gpa. This means that under the same weight, T800 has a stronger bearing capacity and stronger tensile and compressive resistance.
Secondly, in terms of processing technology, T800 adopts a more complex high-temperature oxidation treatment process, which gives it better heat resistance and chemical stability. While T700 adopts the traditional carbonization treatment process, although its heat resistance and chemical stability are worse, its production cost is relatively lower.
In terms of application, due to the superior performance of T800, it is mainly used in fields that require high strength and high modulus, such as aerospace, high-end sports equipment, etc. While T700 is mainly used in some fields that do not require very high strength and modulus, such as automobile manufacturing, building materials, etc.
In summary, both T700 and T800 are excellent carbon fiber materials, each with its own advantages and application fields. When choosing, you need to make a choice based on specific needs and budget. Although T800 has superior performance, its price is also higher; while T700, although slightly inferior in performance, has higher cost-effectiveness.
