Abstract: The production of closed cell foams has recently advanced as the materials gain interest. The purpose of this study was to use the transient plane source (TPS) method to measure the thermal conductivity of AlSi7 closed cell foams. Results showed that thermal conductivity increased with sample density, and experimental results were higher than the predictions of the theoretical models. Measurements were also carried out on different directions of the samples and it was observed that the thermal conductivities were highest in directions with closed outer skin. Due to its non-destructive method, the TPS technique would be an effective means to further investigate foam properties.
