heal.abstract	A theoretical model for the determination of the elastic modulus and thermal expansion coefficient of particulate composites is presented in this work. This model takes into consideration the influence of neighboring spherical particles on the thermomechanical constants of the composite material consisting of matrix and filler. A microstructural dodecahedric composite model which represents the basic cell of the composite at a microscopic scale was transformed to a 4-phase spherical representative volume element (RVE) in order to apply the classical theory of elasticity to this. The obtained theoretical results using this model were compared with experimental results carried out on iron particles reinforced epoxy resin composites as well as with other theoretical values derived from expressions given in the literaturre. Finally, an observation of the fracture surface of the specimens was performed through Scanning Electron Microscopy. © 2006 Springer.	en
