Using solid fillers in an elastomeric matrix is a well-known method for improving the mechanical properties of elastomers. In this hot paper a silica-filled model elastomer was used to study the interparticle connections between the filler particles. It was found that the distance between the particles is a crucial parameter in the mechanics of materials, and was compared to the range of polymer dynamics modification within the system.
