This paper presents an experimental investigation of single and hybrid carbon black and spiky nickel-filled conductive composite to understand the synergy effect when different types and shapes of fillers are combined in a silicone polymer matrix. The electrical and mechanical properties of the conductive composites are measured under a compressive loading cycle. The results showed that the electrical properties of the hybrid conductive polymer composites have a better repeatability at low filler ratio as compared to the virgin nickel or carbon black composite. The new hybrid composite piezoresistive behavior is similar to a high filler ratio nickel composite. This study provided insights to develop a tailored conductive composite with a low mass-ratio and different morphology of fillers.

“…For that reason, rubber composites are an excellent option for several demanding engineering materials and also for ordinary everyday applications. [1][2][3] To address this challenge of meeting diverse technical requirements, rubber composites are prepared with a complex mixture of ingredients that should be properly dispersed and distributed in the rubber viscous matrix. A typical rubber formulation contains many more ingredients when compared to others engineering materials formulations.…”

This study reports the reinforcement degree investigation of two types of rockwool fibers (F1 and F2), in nitrile rubber composites. The micro-computed tomography (micro-CT) 3D images showed that both fibers were well-dispersed in the NBR matrix, without a preferential orientation. The micro-CT analysis also allowed quantifying volume fraction, inter-fiber distance, and aspect ratio. Those morphometric parameters were used for supporting the composites rheological behavior assessment. Changes in the elastic modulus and phase angle followed the same trend of the inter-fiber distance values, regardless the type of fiber. Both volume fraction and aspect ratio data from the micro-CT analysis were used to predict theoretical values of elastic modulus using the Guth-Gold and modified Guth-Gold equations, and the results obtained were compared to the rheological experimental data. This analysis was helpful to better understand the rockwool fibers reinforcement degree differences in the production of the nitrile rubber composites.

“…Out of the plethora of nanofillers discovered, the reinforcing ability of carbon nanotubes (CNT) in rubber matrices has been studied by some researchers. This has been used alone as well as a hybrid filler in elastomer compositions involving natural rubber (NR), styrene butadiene rubber (SBR), chloroprene rubber (CR), and so forth, although the mechanism of interaction has not been understood 3–6 . Silicon carbide nanoparticles, even though used before in plastics such as epoxies, linear low‐density polyethylene (LLDPE), and polypropylene (PP), 7,8 have not been reported extensively as a reinforcing filler for elastomers 9 .…”

The article portrays the synergistic reinforcement of new generation nanofillers such as silicon carbide nanofibers (SiCs), carbon nanotubes (CNTs), and graphite nanofibers (GNFs) when used along with carbon black (CB) in a typical tire tread composition. The unique synergism in these composites, which were fabricated by a liquid phase mixing method, was reflected in their enhanced failure resistance and dynamic mechanical properties. At 4 phr loading of the nanofiber, the tensile strength, tear strength, modulus at 300% elongation, storage modulus, rolling resistance, and abrasion resistance were improved by 29, 45, 36, 110, 15, and 14%, respectively. The role of nanofibers in the development of a hybrid microstructure was investigated by scanning and transmission electron microscopy. Tribological characteristics were studied using a Laboratory Abrasion Tester (LAT 100), and the abrasion loss of the samples was correlated with energy dissipation occurring during the process. The fatigue properties indicated the ability of the CB-nanofiber dual filler system to arrest crack growth. The study also serves to establish a correlation between the wear loss and fatigue properties of the hybrid nanocomposites containing different fibrous nanofillers. A mechanism of reinforcement by hybrid fillers is proposed.
