Thermal conductivity of Al/AlN interpenetrating phase composites with different preform porosity

In this investigation, the thermal conductive (TC) properties of the Al/AlN interpenetrating phase composites (IPCs) with varying preform porosity at different temperatures (20°C to 200°C) were studied. The TC values obtained through experimentation were compared to predictions generated by analytical models. IPCs with higher preform porosity exhibit higher TC. The TC of IPCs exhibits an inverse temperature dependence. Theoretical models accurately predict the thermal conductivity of IPCs with high preform porosity.
