In numerous industries beyond rail vehicle technology, the utilization of continuous fiber reinforced plastics (FRP) has already gained prominence alongside conventional metallic materials due to their exceptional lightweight potential. However, the application of such materials in rail vehicles encounters limitations, including stringent fire protection requirements, the need to establish new repair processes, feasibility of recycling, and higher manufacturing costs. To address these challenges and facilitate the structural implementation of FRP in rail vehicles, a comprehensive approach has been developed. This approach primarily encompasses material selection, design, simulation, and relevant manufacturing technologies, while also considering the intricate interactions among these factors. Through the successful application of this approach, a remarkable breakthrough has been realized: the design and fabrication of an exceptionally robust, high-impact structure positioned beneath the car body of a high-speed train. One cornerstone of this approach is a multi-stage material selection process that meticulously evaluates both general and rail-specific requirements. These encompass fire safety, thermal stability within operational temperature ranges, recyclability, static strength, fatigue resistance, manufacturability, and numerous other critical factors. Leveraging the outcomes of this rigorous material selection process, an innovative design strategy guided by advanced simulation techniques was employed to craft a resilient and cost-effective component using carbon fiber-reinforced thermoplastics (CFRTP).
