- High Strength-to-Weight Ratio:
Its tensile strength is 7 to 9 times that of steel, while its specific gravity is less than a quarter of steel. This means that under the same volume, carbon fiber is much lighter than steel, but its tensile strength is much higher than steel. In the automotive industry, carbon fiber is used to manufacture body and chassis components to reduce weight and improve vehicle performance.
- High Stiffness:The stiffness coefficient of carbon fiber is usually around 230GPa, which is much higher than that of traditional steel and aluminum materials, demonstrating the superiority of carbon fiber in engineering applications. Carbon fiber is widely used in the manufacturing of structural components for aircraft and rockets due to its high strength and modulus.
- High-Temperature Tolerance:Carbon fiber has extremely high heat resistance and can maintain stability in high temperature environments. The temperature resistance range of carbon fiber is very wide, usually maintaining stability at high temperatures of 1500 to 3000 degrees Celsius, making it an ideal material for manufacturing high-tech equipment such as aerospace.
- Corrosion Resistance:
It can withstand various acids, alkalis, and oils, and its corrosion resistance is even better than gold and platinum. In addition, carbon fiber composite materials can also withstand the corrosion of water and various media in nature, as well as the influence of thermal expansion. These advantages make carbon fiber material products have a very long service life, especially suitable for long-term operation and applications in contact with oil stains.
- Low Thermal Expansion:
Compared with traditional metal materials, carbon fiber composite materials have significant advantages in that they will not deform or explode even under large temperature differences. It is widely used in high-temperature environments in aerospace, automotive, marine and other fields, such as aircraft engine components, high-performance racing car components, etc.
