Article Synopsis
- Active fillers like carbon black and silica enhance the mechanical and viscoelastic properties of rubber through various interactions, affecting the compound's behavior.
- The study examines the effects of different silica loadings on three types of solution styrene-butadiene rubbers (SSBR) and one butadiene rubber (BR), finding that higher filler loading increases viscosity and hardness but can also worsen properties in BR due to weak polymer-filler interactions.
- An optimum filler loading was identified, where mechanical properties improved up to a point before declining, influenced by the type of rubber, amount of filler, and temperature.
A comparative study focusing on the visco-elastic properties of two series of carbon black filled composites with natural rubber (NR) and its blends with butadiene rubber (NR-BR) as matrices is reported. Strain sweeps at different temperatures are performed. Filler network-related contributions to reinforcement (ΔG') are quantified by the classical Kraus equation while a modified Kraus equation is used to quantify different contributions to dissipation (ΔGD″, ΔGF″).

Rubber-filler and filler-filler interactions can be influenced by various material factors, such as the presence of processing aids. Although different processing aids, especially the plasticizers, and their effects on compatibility have been investigated in the literature, their influence on rubber-filler interactions in highly active filler reinforced mixtures is not explicit and has not been investigated in depth.

Article Synopsis
- The roughness profiles of fracture surfaces in filled rubber were analyzed using height-height correlation functions, revealing anisotropic behavior with different roughness exponents based on direction.
- A two-dimensional analysis indicated the presence of Family-Vicsek scaling, characterized by two specific exponents within a certain range of length scales.
- The observed roughness exponents in the rubber were similar to those found in nonrubber materials, suggesting that ductile fracture processes occur within this specific length scale range.
