Abstract: It is showing that the mutual arrangement of composition elements, as there combination are affected to the thermal expansion and elasticity of dispersed-filled polymer composite materials. This made it possible to substantiate the difference in the results of theoretical models and experiments of that characteristic. It is showing that using the empirical coefficients into the mixture model can take into account the mutual arrangement of the elements of the composition.

Keywords: polymer composites, particulate fillers, coefficient of linear thermal expansion, voids, rule-of-mixtures model.
