1.Good seismic resistance
2. Lightweight
3. High rigidity and corrosion resistance
4. Good safety
5. Increased the freedom of structural design
The tensile strength of carbon fiber composite materials can reach 3500Mpa, which is 7-9 times that of steel, and the tensile modulus can reach 300Gpa, which is about 1.5 times of high strength. The shear modulus is equivalent to steel, and the density of carbon fiber is only about 1.6 g/cm3, which is about 40% lighter than aluminum. In addition, carbon fiber composite materials also have the advantages of large damping, good fatigue resistance, low vibration, and corrosion resistance.
