“…[14][15][16]. Besides these studies, many material developments for a better silica dispersion, such as the modification of polymers, silica, and silanes, are going on [17][18][19][20][21]. Overall, these studies primarily indicate that the silanization reaction plays a pivotal role for the dispersion and the bound rubber formation of a silica-filled rubber [22][23][24][25].…”

The Effect of Silanization Temperature and Time on the Marching Modulus of Silica-Filled Tire Tread Compounds

Marching modulus phenomena are often observed in silica-reinforced solution styrene–butadiene rubber/butadiene rubber (S-SBR/BR) tire tread compounds. When such a situation happens, it is difficult to determine the optimum curing time, and as a consequence the physical properties of the rubber vulcanizates may vary. Previous studies have demonstrated that the curing behavior of silica compounds is related to the degree of silanization. For the present work, the effect of silanization temperature and time on the marching modulus of silica-filled rubber was evaluated. The correlations between these mixing parameters and their effect on the factors that have a strong relation with marching modulus intensity (MMI) were investigated: the amount of bound rubber, the filler flocculation rate (FFR), and the filler–polymer coupling rate (CR). The MMI was monitored by measuring the vulcanization rheograms using a rubber process analyzer (RPA) at small (approximately 7%) and large (approximately 42%) strain in order to discriminate the effects of filler–filler and filler–polymer interactions on the marching modulus of silica-filled rubber compounds. The results were interpreted via the correlation between these factors and their effect on the MMI. A higher temperature and a longer silanization time led to a better degree of silanization, in order of decreasing influence.

“…According to investigations, higher surface area of silica resulted to an increased reinforcing effect due to strong polymer-filler while decreasing filler-filler interactions [163]. In addition, the large surface area of bamboo charcoal (BC) particles improved the stress transfer properties between PLA to BC enhanced strength and ductility index of the PLA-BC composite [164].…”

Polylactic acid (PLA) has increasingly attracted research in various industrial fields due to its great biocompatibility and sustainability over other thermoplastics, which are widely used as filament feedstock in 3D-printing technology, specifically in Fused Deposition Modelling (FDM). Despite PLA being suitable in FDM processing, it has limitations in applications that need plastic deformation at high-stress levels due to its low strength and ductility. For this purpose, this review article discusses the existing studies that involve the incorporation of fillers in 3D-printed polylactic acid to maximize its functionality, which is non-attainable by the pure filament material alone. An overview of polylactic acid in FDM and the properties and effects of functional fillers of different types are presented. Finally, a complete table of which functional fillers are categorized (carbonaceous, metallic, ceramic and glassy, plant-based, and mineral) summarizes the reported comparison of 3D-printed pure PLA and the composite, scoping to reveal the mechanical modifications of each filler.

“…Down the lane, researchers had been working to develop green technologies in tyre manufacturing to obtain a balance between rolling resistance and road grip. To reduce the rolling resistance, modifications can be made to the rubber compound, tread design and tyre build [ 22 ]. Accordingly, the viscoelastic properties (mainly loss factor) of the rubber compound were modified by the usage of silica fillers, other nanomaterials and steps taken to improve the filler dispersion in the compound, improvised the crosslinking process and also increased the usage of natural rubber [ 22 ].…”

It was found that tread contributed to more than 60% of the total tyre losses and hence changes were also introduced in the tread design by providing nano coatings to tread, reducing the depth of the tread pattern and introducing 3D shaping technology.…”

Growing natural calamities as a consequence of global warming are one of the most pondering subjects today. The exponential growth of environmental pollution due to unscientific human exploitation of natural resources is considered the prime reason for the harsh responses of nature. Researchers from various fields of industry and academia are working hard to develop and implement products/technologies that are environmentally friendly or less harmful to the ecosystem. Material researchers, specifically those working in the automobile sector are also not behind in search of green products from eco-friendly raw materials and production methods. The automobile industry is collectively responsible for around 40% of global pollution in terms of greenhouse gas emissions. Out of which around 20–30% is originating from tyre production and its end-use. In this view, tyre production from eco-friendly raw materials and technologies that have minimum hazardousness to the environment is a hot research topic today. A few products in the market with “green” tags and many are in the pipeline for the recent future. This review summarises a detailed discussion of the emerging green technologies for tyre production and depicted comprehensive data from the available literature. The paper has been drafted from a well-balanced academic and industrial point of view since the researchers from both sectors are working in harmony for a better future for green tyre technology.
