(I001_1)Temperature dependence of Emissivity and Electrical Resistivity of Carbon Fiber

摘要

We are developing thermal expansion measurement system for carbon fibers. In this system, the temperature distribution of sample, which is monofilament less than 10μm in diameter, is measured by microscope thermography, and the sample temperature is controlled by adjusting current passing through the sample. Therefore, the emissivity and electrical resistivity of a carbon fiber have been determined for measuring and controlling the temperature of the sample fiber in the thermal expansion measurement.
