| Abstract: | Based on the application of railway vehicle body sandwich composites, through the study of mechanical and fire-retardant property of foam core, the core material selection of vehicle body sandwich structure was carried out. The research showed that the developed PMI foam/aluminum sandwich structure body parts were assembled into a railway vehicle body, and the weight of PMI foam/aluminum sandwich structure body was reduced by 24%-28% compared with the same type aluminum alloy body. Also, the aluminum skin sandwich structure vehicle body had greater advantages in cost, efficiency, safety and maturity compared with the fiber resin skin sandwich composites. |
