โœฆ Synopsis

The "steady" sinusoidal technique employed previously to determine the thermal diffusivity in carbons has been improved and its temperature range extended. In this technique a sinusoidal heat input occurs at one end of a thin walled tube placed in a uniformly heated container and the variation in temperature is observed at various points along the tube. Measurements of the longitudinal diffusivity were performed in the temperature range 40-1200ยฐC on various types of carbons graphitized at about 2800ยฐC.

The influence on the thermal diffusivity of the changes induced on the macromolecular network of an epoxy-amine system by different hardener/resin ratios was experimentally investigated. For each hardener/resin ratio, the open photoacoustic cell technique was used to measure the thermal diffusivity.
