For a better understanding of such materials, we perform Monte Carlo simulations on several bulk atomic structures. First, we built a united atom coarse grained model of resol and silica. The precursors interact weakly with each other and can form chemical bounds independently. We explore, numerically, the structural properties of the nanocomposite by adjusting the initial mass ratios of silica to resol. The degree of the polymerization is adjusted by decreasing the volume of the simulation box at different rates, corresponding to a fictitious evaporation of the solvent. We show how mechanical properties are reinforced as a function of the molecular weight of the polymer (resol). This preliminary study is the first step to investigate the mechanical properties of the nanocomposite templated by micelles.
