Through the analysis of the current situation and technical characteristics of high speed train, combined with the investigation of performance advantages and industrial situation of fiber composite materials,the necessities of diversified development of structures and materials have been revealed. This article points out that the application of fiber composite materials is an effective way to realize the balanced development of all the performance of high speed train. Elaborating on the applications of composite products for high speed EMU both domestically and interuationally,the paper described fiber composite component under CRRC Sifang integrated design concept. We predicted the future work for composite materials applied in EMU and proposed feasible advice to promote the application of carbon fiber reinforced polymer （CFRP） in China railway transport in order to improve our international competitiveness and influence in this area.
