금속계 마찰재에 첨가된 Graphite 형상에 따른 마찰특성 연구

초록

The essential element of brake device for railway vehicle is in demand for higher performance alongside the trend of railway vehicle size and speed. Essential element of brake device for High Speed Train is composed of Metallic Friction Material and Brake Disc. Thus, brake distance, duration and brake stability shall be determined due to Friction Materials and Friction Characteristics. Also Friction Characteristics are influenced by Metallic Friction Material’s properties of matter, manufacturing process and component parts. Various materials and configurations of Metallic Friction Materials are currently being implemented to railway vehicles, for this reason study of friction Characteristics in accordance with materials is necessary, but study of these important elements are not actively being accomplished. Therefore, in this study, wished to study the Graphite’s Friction Characteristic comprised in Friction Material in accordance with particle size and amount of volume through Lab-scale test.
