Thermal conduction coefficient of carbon fiber reinforced cement-based composite material

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.
