University of Tokyo trial of high-speed rail hybrid ceramic material with lightweight brake disc

Tokyo University to participate in research projects developed with hybrid ceramic material, is not easily broken and lightweight characteristics may be used in the field of high-speed rail brake. The project used the trial out of the material Shinkansen brake disc and solve the technical issues of the physical properties and production. Estimated maglev train, car, high-speed lifts, brake material, as well as aerospace use materials can be used in the future.
The hybrid ceramic according to need to be configured in a member different characteristics of the ceramic material. Manufacturing a brake disk of this project, the vicinity of the surface thereof is an anti excellent fracture properties of the carbon fiber reinforced SiC ceramics, the internal strength is excellent SiC ceramic material monomer.
On the molding method to establish a net molding process, can be directly manufactured as a member using a shape, reduce the manufacturing cost. Specifically, (1) is developed having a nanostructure mixed preform manufacturing technology and (2) high-speed net molding technique. The carbon fibers are dispersed in the SiC, the shape of the brake disk can be formed simultaneously.
The project is through the practical application of research and development of nanotechnology tip member of Japan's New Energy and Industrial Technology Development Organization (NEDO) project to start the second half of 2008. To participate in the project with state-of-the-art science and technology research center of the University of Tokyo, Japan Covalent Materials Corporation (Headquarters: Tokyo), the Japan Aerospace Exploration Agency, Japan's National Institute for Materials, University of Tokyo Institute of Industrial Science. The project leader is the state-of-the-art scientific and technological research center of the University of Tokyo professor Kagawa abundance. Responsible for the development of industrial and manufacturing technology of the brake disc by Covalent Materials.
