Functionally Graded Materials (FGMs) are a class of composites materials with promising applications due to their interesting properties. The properties of these materials change gradually and depend on the architecture of the microstructure. The purpose of this work is to develop new materials based on a ceramic matrix reinforced with aluminum particles. An improvement of thermal properties of this material is achieved by optimizing the architecture of interconnected aluminum particles. The inter-particle contact condition (overlapping region) and the particle radii control the heat conduction within the particulate material. A numerical model was developed to optimize thermally the architecture of the phases. The method is based on both Discrete Element Method and Finite Element Method. This study introduces a new process for building FGMs and presents a numerical procedure in order to investigate the effects of the architecture on the effective thermal properties of the materials.
