T300 is a high-strength carbon fiber that is commonly used in the aerospace and sporting goods industries. It is made from polyacrylonitrile (PAN) precursor and has a tensile strength of 350 ksi (kilopounds per square inch) and a modulus of elasticity of 33 msi (million pounds per square inch). T300 carbon fiber is known for its excellent strength-to-weight ratio, good fatigue resistance, and low coefficient of thermal expansion.
T700 is a higher-grade carbon fiber than T300 and is used in more demanding applications such as aerospace and high-performance sporting goods. It is also made from PAN precursor and has a tensile strength of 700 ksi and a modulus of elasticity of 33 msi. T700 carbon fiber is known for its superior stiffness, strength, and fatigue resistance.
Carbon fiber has become a popular material for a wide range of applications, from aerospace to automotive and sports equipment. In particular, two types of carbon fiber, T300 and T700, are frequently compared due to their different properties and applications. In this article, we will explore the differences between T300 and T700 carbon fiber.
The chemical groups of T300 and T700 contain carbon, but the carbon content of T700 is higher than that of T300. The carbon content of T700 carbon fiber is 95.58% and that of T300 is 92.5%. The carbonization temperature of T700 is higher than that of T300, and the carbon element is more stable.
T300 is a type of high-strength carbon fiber that has been used for several decades. It is widely used in the aerospace industry due to its excellent mechanical properties, including high strength, stiffness, and fatigue resistance. T300 carbon fiber has a tensile strength of approximately 1,000 MPa and a modulus of 34 GPa.
In contrast, T700 carbon fiber is a more recent development and has been used extensively in the automotive and sports equipment industries. T700 is considered a higher grade carbon fiber and has a tensile strength of approximately 1,400 MPa and a modulus of 65 GPa. Compared to T300, T700 is lighter, stiffer, and stronger, making it an excellent choice for applications that require high strength and stiffness, such as sports equipment and high-performance cars.
Another key difference between T300 and T700 carbon fibers is their manufacturing process. T300 adopts wet spinning process while T700 adopts dry jet wet spinning process. T700 carbon fiber is typically produced using a more advanced manufacturing process, which results in a more consistent and higher quality material. This process involves using a higher temperature during the production process, resulting in a higher degree of crystallization and a more uniform material structure.
T300 carbon fiber is commonly used in the aerospace industry for structural components, such as aircraft wings, fuselages, and tail sections. It is also used in the sporting goods industry for products such as tennis rackets, bicycle frames, and fishing rods.
T700 carbon fiber is used in high-performance aerospace applications such as military aircraft, satellites, and rockets. It is also used in the sporting goods industry for high-end products such as racing bicycles, high-performance golf clubs, and high-end fishing rods.
In conclusion, both T300 and T700 carbon fiber composites have excellent properties and are widely used in various applications. T300 is an excellent choice for applications that require high strength, good fatigue resistance, and low cost. T700, on the other hand, is ideal for applications that require high stiffness, superior strength, and exceptional fatigue resistance. Ultimately, the choice between T300 and T700 carbon fiber depends on the specific application, cost considerations, and performance requirements.
