Application of Composite Materials in High-speed Train

The application of composite materials in high sepped trains is reviewed. With the increase of train speed, the lightness in weight and some special characteristics are demanded so that composite materials are soon chosen to manufacture the components of locomotives and cars, such as car body, bogie, braking parts and so on. Even some of expensive composite materials originally used in aviation and space flight are finding the way to be applied in high speed trains and many new kinds of composite materials will be developed.
