Carbon Fiber Reinforced

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.

Polyvinyl alcohol fiber reinforced cement-based composites are a new kind of material based on micro mechanics design. It is produced by adding polyvinyl alcohol fiber in the cement-based composites. In efforts to study the mechanical properties of polyvinyl alcohol fiber reinforced cement-based composites, some specimens were tested to examine performances. According to experimental investigation on mechanical properties, the stress-strain relationship curves and failure patterns are obtained. The test indicates that polyvinyl alcohol fiber reinforced cement-based composites have better toughness and fracture energy, and it has superior physical mechanical performance.
