A carbon contact strip using rice bran (RB) ceramics has been developed. RB ceramics are porous hard carbon materials that inhibit high wear resistance. In this study, the compliance characteristics of the RB ceramics contact strip and the contact break rate were investigated. The contact strip showed the same compliance characteristics as an existing contact strip and smaller contact break rates. Furthermore, the wear properties of the RB ceramics contact strip and a trolley wire in running tests with actual trains were investigated. The mean wear rate of the RB ceramics contact strip was 2.3 times higher than that of the existing contact strip. The wear rates of trolley wires sliding against the RB ceramics contact strip were approximately the same as those sliding against the existing contact strip, which did not affect the regular maintenance cycles of the trolley wires. On the basis of these results, the RB ceramics contact strip has potential for application as a real-world contact strip.
