The successful development of the full carbon fiber composite material and the large-size car body load-bearing structure has verified the feasibility of the carbon fiber composite material used in the rail transit load-bearing structure. However, the application of carbon fiber composite materials in rail vehicles is still in its infancy, and it is still limited by cost, materials, design, process, etc. Especially the cost problem is a strong barrier restricting its promotion and application. The following aspects should be boosted in order to promote the continuous and rapid development of carbon fiber technology and the application of rail transit composite car bodies.
1. In-depth development of basic research on carbon fiber materials
2. Carry out research on the structural design of carbon fiber composite materials
3. Strengthen the optimization research of the composite material structure forming process
4. Establish a composite material standard system suitable for the rail transit industry
5. Improve carbon fiber production capacity and level
The promotion and application of carbon fiber in the body of rail transit vehicles is a major opportunity and challenge for the composite material industry. Although currently constrained by manufacturing costs, molding processes, and production efficiency, and it is difficult to achieve mass production in the short term, it is believed that in the near future, China will usher in another revolution in the application of new materials for rail vehicle bodywork with the improvement of new materials and new technologies.
