Experimental Study of Thermal Conductivity of Carbon Fiber Reinforced Cement-Based Composites

Article Preview

Abstract:

This paper studies the carbon fiber weight influencing on the thermal conductivity of carbon fiber reinforced cement-based composites. Experiment results show that the thermal conductivity decreases with the increase of carbon fiber weight. It is because that the air bubble results from the proceeding when the carbon fiber adds into cement-based composites. When the carbon fiber weight is less than 1.0%(by mass), the thermal conductivity decreases significantly. And when the weight is more than 1.0%, the decreasing tendency starts to slow down. Based on the experiment data, the functional relationship between the thermal conductivity and carbon fiber weight is obtained by using the fitting method.
