| Abstract: | The development of high-speed train and its composites all over the world are introduced.The problems taking place with increase of train′s speed and the main approaches for its speeding are analyzed.Performances of sandwich structure composites and the trend of that sandwich structures substituted laminates are described.And the method that the structural components of high-speed train are manufactured by 3D integrated composite sandwich structures,which can cover the shortage of insufficient of the large structural components′ bending stiffness which manufactured by traditional foam core sandwich structures,is suggested. |
