摘　　要：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。Mixed graphite cement-based materials with short-cut carbon fiber with low resistivity and crack resistance function can improve the conductive performance of materials. The effects of the ambient temperature, fiber length and composite length of carbon fiber on material resistivity are studied through tests. The results show that the carbon fiber can improve the performances of graphite cement-based materials and the composite length of carbon fiber is beneficial to the formation of conductive network of materials.
