摘　　要：文章采用了镀铜石墨粉制成碳刷试样,分析了镀铜石墨复合碳刷的微观结构、体积密度、电阻率等性能,最后讨论了外加石墨粉及改性酚醛树脂时试样的性能。实验结果表明,镀铜石墨粉制备的碳刷综合性能明显优于石墨粉与铜粉直接混合制备的碳刷。The copper-coated graphite powders to make samples are used in this paper. These samples are analyzed about microstructure, volume-density and resistance rate and so on. At last, this paper discusses the samples＇ properties when the other graphite powders and phenol-formaldehyde resin modified are added. Experiment results show the integrative properties of carbon brush made by copper-coated graphite powders are obviously better than that made by copper powders and graphite powders in mixing method directly.
