A Rheo-Optical Study on Reinforcement Effect of Silica Particle Filled Rubber
In order to clarify the filler effect
on rubbers, rheo-optical
measurements were performed for unfilled and filled samples of a styrene–butadiene
rubber/silica system. Refractive index matching was performed to increase
transparency of samples and to reduce form birefringence of particles.
The component stress of matrix rubber and the filler was successfully
determined by using the strain-induced birefringence data. Our results
were consistent with the composite model in micromechanics if the
vitrified rubber layer is consider on the surface of fillers. On the
basis of the experimental results, we proposed a phenomenological
equation for large tensile properties for ideal filled rubbers
