This research investigates the effects of nano-reinforcement materials on the mechanical properties of rubber samples. The study finds that precipitated silica can improve the properties of rubber, while a combination of graphene nanoplatelets and carbon black can effectively enhance the tensile strength and elongation at break of rubber. However, the addition of graphene nanoplatelets negatively affects the abrasion resistance of the samples.
The complex structure of tyres makes them hard to recycle economically; hence, it is crucial to minimize the generation of tyre waste. Nano-reinforcement, such as graphene, has the potential to increase the abrasion resistance of rubber and thus their lifespan as well. In this research, hybrid styrene-butadiene rubber-based (SBR) nanocomposites reinforced with carbon black, silica and various amounts of graphene nanoplatelets are investigated with great emphasis on their combined effects on the mechanical properties of the rubber samples. Sixty-five phr of precipitated silica can holistically improve the properties of SBR. However, further addition of carbon black and graphene nanoplatelets to silica-containing samples do not benefit the properties of the samples. Further studies on the compatibilization of silica with carbon-based reinforcement are necessary. On the other hand, graphene and carbon black constitute an effective hybrid reinforcement system. The tensile strength and elongation at break of SBR are improved by almost 100% with 10 phr of graphene nanoplatelets in combination with 10 phr of carbon black. However, the abrasion resistance of samples was negatively influenced by the addition of graphene nanoplatelets whenever it was added in combination with other fillers. Silica was particularly effective in increasing the abrasion resistance of rubber.
