摘　　要：研究了碳纤维含量对水泥基复合材料导热系数的影响。试验结果表明:由于碳纤维加入水泥基材料中的同时也引入了气泡,导热系数随着碳纤维含量的增加而降低,碳纤维含量小于1.0%时,下降的幅度较大;含量大于1.0%时,下降的幅度变缓。通过对试验数据拟合得到了导热系数随碳纤维含量变化的函数关系。The effect of fiber content on thermal conduction coefficient of carbon fiber reinforced cement-based composite material was investigated.Results show that thermal conduction coefficient reduces with carbon fiber content increasing, for which carbon fiber adds at the same time in cement-based composite material have also led into air bubble.When carbon fiber content is less than 1.0% （by mass）, the reducing extent of thermal conduction coefficient is bigger than the coefficient change situation when the fiber is more than 1.0%.The functional relationship between thermal conduction coefficient and carbon fiber content is obtained by regression analysis.
