碳纤维增强水泥混凝土导电机理的研究

Study on the Mechanism of Electrical Conductivity of Carbon Fiber Reinforced Concrete

研究了沥青碳纤维掺量及外加剂对碳纤维混凝土复合材料导电性的影响 ,讨论了碳纤维混凝土复合体的导电机理。结果表明 :碳纤维掺量对复合材料的导电性有一个临界值 (Vfc) 。

The effects of addition and additional amounts of pitch based carbon fiber on electrical conductivity of carbon fiber reinforced lightweight concrete(CFRC)were investigated.The mechanism of CFRC's electrical conductivity was discussed.The results show that there is a limit to the effects of amounts of pitch based carbon fiber on electrical conductivity of CFRC,the addition can lower CFRC's electrical conductivity.
