Chinese enterprise develops world’s first carbon fiber composite vehicle body

A Chinese enterprise has developed the world’s first carbon fiber composite vehicle body, which is 35 percent lighter than metal ones.

The Chinese state-owned enterprise, CRRC Changchun Railway Vehicles Co., Ltd, has exclusive rights in developing and testing the carbon fiber composite body, making China a world leader in adopting the material in rail transit industry.

Due to its special physical characteristics, the car body is 35 percent lighter than metal ones, which can improve carrying capacity and reduce energy consumption and damage to circuits, according to People’s Daily.

The carbon fiber composite material also shows excellent performance under extreme conditions and severe environments.

In addition, owing to its extraordinary resistance to fatigue, corrosion, and ultraviolet aging, its service life can be more than 30 years.

Also, the body is more advantageous than metal ones in terms of insulation and vibration damping, which can reduce internal noise and vibration during operation, improving passengers' comfortableness.
