在石墨水泥基材料中掺入低电阻率且具有阻裂功能的短切碳纤维可以提高材料的导电性能。试验研究了环境温度、碳纤维长度及组合长度碳纤维等对石墨水泥基材料电阻率的影响。结果表明,碳纤维可以改善石墨水泥基材料的性能,组合长度碳纤维的掺入有利于材料导电网络的形成。
Incorporation of low resistivity and chopped carbon fibers in graphite cement-based materials can improve the conductivity of materials. The effects of ambient temperature, carbon fiber length and carbon fiber length on the resistivity of graphite cement based materials were studied. The results show that carbon fiber can improve the performance of graphite cement-based materials. The incorporation of carbon fiber with the combined length is conducive to the formation of conductive network.
