Small-angle X-ray scattering indicates that increase of the silica particle (PSP) content leads to changes in the fractal organization of epoxy-silica composites and in the number of levels of self-similarity. Fractal structures of the primary silica particles in the size range of 4-14 nm are formed, and with increasing particle size they aggregate to form surface fractals with sizes of ~35-40 nm in the polymeric matrix of the composites.
