1. Vehicle body structural materials

Carbon fiber is widely used as a structural material for ultra high speed rail transit due to its high strength, high rigidity, and lightweight characteristics. The vehicle body structure made of carbon fiber materials has stronger fatigue resistance and corrosion resistance, which can significantly improve the service life and safety of the vehicle. At the same time, carbon fiber materials can also improve the insulation and sound insulation performance of vehicles, enhancing passenger comfort.

2. Bogie material

Bogie is one of the key components of ultra high speed rail transit vehicles, and its performance can directly affect the safety and comfort of vehicle operation. Carbon fiber is widely used in the manufacturing of bogies due to its high strength, high rigidity, and lightweight characteristics. Bogies made of carbon fiber materials have better fatigue resistance and corrosion resistance, which can significantly improve the operational safety and service life of vehicles.

3. Brake system materials

The braking system of ultra high speed rail transit vehicles needs to have high friction coefficient, high wear resistance, and lightweight characteristics. Carbon fiber is widely used in the manufacturing of brake pads and brake wheels due to its good friction performance and corrosion resistance. The brake system made of carbon fiber materials has better braking performance and wear resistance, which can significantly improve the operational safety and service life of vehicles.
