Developing trends in disc brake technology for rail application The substitution of conventional ferrous materials by light‐alloy solutions gives the opportunity for significant reduction of the rotating masses in the bogie and by that a decrease of energy consumption. The potential of conventional Al‐cast‐alloys is not suitable to solve this. Castable MMC‐materials are a high‐promising alternative. Under economic pressure MMC‐solutions need not to be only superior but also cost effective. And due to the low ductility of those particulate reinforced materials there is a need for new concepts. Locally optimised disks consist of a ductile carrier [body] with wear resistant rubbing surfaces. This led to several prototype disk brakes manufactured by different casting processes. This paper gives an overview about the state‐of the‐art and newly developed manufacturing routes and materials, metallic and non‐ metallic, for rail disk brake application.
