Linear elastic properties of silicone rubbers filled with nano- and micro-silica particles

Linear elastic properties of the rubber composites filled with nano- and micro-particles were discussed on the basis of the experimental results for the silicone rubbers filled with the silica particles and theoretical analysis. Because the nano-particles behaved in the composite as apparent particl...
