Mechanical-thermal coupling mechanisms in silicone foam (SF) composites play a crucial role in optimizing their performance for aerospace, automotive, and construction applications, where lightweight design and thermal efficiency are essential. This study presents a comprehensive theoretical framework to evaluate the mechanical and thermal properties of SF composites reinforced by carbon fibers (CF) and aluminum particles (Al) under axial pressure. A four-phase composite model is developed to incorporate inclusions, matrix and voids, accounting for morphological changes in the foam structure. ...
