A copper-graphite brush is used as a sliding part in the electrical contacts of electrical machines and usually operates at elevated temperatures. This experimental research relates the dynamic properties of the copper-graphite brush to its wear rate at elevated temperatures. The dynamic and material properties were researched using a dynamic response analysis, hardness test and differential scanning calorimetry. The results show that there is a key temperature range where the material properties of copper-graphite brush was changed and which reflects on the increases of damping by 15% and hardness decreases by 50 %.
