✦ Synopsis

The effect of heat-treatment on the thermal diffusivity of an aluminosilicate fiber-reinforced carbon matrix was measured by the laser-flash method while the specimen was being heat treated. A permanent increase in thermal diffusivity was observed, which was attributed to the combined effects of structural modifications in the carbon at the atomic or molecular level, a change in the morphology of the pore phase within the carbon matrix, and possibly the crystallization of the fibers.
