THEORETICAL DESCRIPTION OF PORES IN THE SIMULATION OF COMPOSITE-MATERIALS

The influence of porosity on the electric conductivity and the dielect ric constants of composite materials was studied using computer simula tion (the Monte Carlo method). A new approach to the simulation of por ous systems that treats pores as a component equivalent to the solid p hase components was proposed. Within the framework of this approach, a n analysis of the influence of the micro- and macroporosity on the ele ctric conductivity was carried out. It was established that the concep t of a barrier-disordered system is also valid for pores. It was shown for the first time that pores can serve as one of the factors that fo rms the contact barrier distribution function. The proposed theoretica l models were in good agreement with the experimental data.
