説明
Shirasu/Aluminum functionally gradient materials (FGMs) were successfully fabricated by centrifugal casting method, where Shirasu is volcanic eruptions accumulated over the south kyushu in Japan. Thermal conductivity of Shirasu/Aluminum FGM was measured by a comparative method in two directions, i. e. perpendicular and parallel to the gradient direction. The thermal conductivity was theoretically estimated using the equation derived by Bruggeman both on Shirasu/Aluminum FGMs and uniformly dispersed Shirasu/Aluminum composites. It has been found that the thermal conductivity of the Shirasu/Aluminum FGMs in the perpendicular direction to the gradient is larger than that in the parallel direction. The anisotropy in the thermal conductivity obtained by the experiment is found to be larger than that predicted by the calculation. Since the Shirasu/Aluminum FGM has a strong anisotoropy in the thermal conductivity, this FGM can be used as a good heat-insulating material, compared with the uniform composite which contains the same amount of Shirasu.
