The Super-speed Maglev System Trans-rapid - Profitability due to innovative composite construction and progress in manufacturing technology. The Super-speed Maglev System Trans-rapid is the world's most advanced, track-bound transportation system. Non-contact electromagnetic levitation, guidance and propulsion technology enables operation at high cruising speeds up to 500 km/h with a minimum of wear and tear, low energy consumption and high ride comfort. In order to provide light and stiff components innovative composite structures are used. For the structure of the carriage bodies, a hybrid design using aluminum hollow profiles and aluminum clad foam sandwich panels is chosen. The nose elements are self-supporting sandwich structures made from Glass Fibre Reinforced/Polyester resin cladding layers with a foam core. The various structural components are joined using mechanical fixing systems, welding and adhesive bonding. Laser welding is used to secure and seal one of the aluminum cladding sheets to the edging profiles which are integrated into the sandwich panels. The magnet poles as parts of the levitation system are assembled and sealed with resin based on epoxy components. To ensure a high and constant quality standard in the magnet p01 production a new process known as automatic pressure gelation is applied.
