“…The composite specimens with the highest density were observed in the BP_10 specimen of 1.881 g/cm 3 . Conversely, the BP_30 specimen had the lowest density of 1.869 g/cm 3 . This is due to the possibility that the constituent materials may be damaged by the increased pressure during the molding process.…”

“…Figure 1 shows the relationship between compression molding pressure and composite specimen density. The densities of the samples subjected to pressures of 10 MPa, 20 MPa, and 30 MPa were 1.881 g/cm 3 , 1.879 g/cm 3 , and 1.869 g/cm 3 , respectively. The findings of the study indicated that increasing compression molding pressure results in decreased composite specimen density.…”

“…Moreover, they noted that high-pressure processing could cause the porosity of composite specimens to close. According to a study by Patel et al, 47 natural fiberreinforced epoxy composites utilized in the automotive and construction industries have a density ranging from 1.08 to 1.35 g/cm 3 . In another study, the density of kenaf/ GNPs/epoxy composites manufactured via vacuum infusion molding for automotive applications is 1.18-1.19 g/cm 3 , according to research by Malik et al 48 The densities obtained in this investigation were more significant than those obtained in prior research.…”

“…Furthermore, the emissions from motor vehicles harm the environment and atmosphere, resulting in adverse atmospheric phenomena, such as global warming and changes in the climate. [3][4][5][6][7] Pradeep et al 8 state that automotive vehicle manufacturers are actively researching lightweight materials for automotive vehicle applications. The intention is to enhance fuel efficiency by achieving a 6%-8% increase for every 10% reduction in vehicle weight.…”

The need to comply with environmental regulations and provisions set by the government for sustainability and environmental awareness has caused the use of natural fiber‐reinforced composites in the automotive industry to increase. Furthermore, there has been a lack of extensive research on the production of eco‐friendly composites for automotive applications utilizing epoxy resin, rice husk, Al2O3, and Fe2O3 by the compression molding technique. Therefore, the objective of this study is to determine the influence of compression molding pressure on the properties of eco‐friendly composites for automotive applications. The specimens consisted of epoxy resin, rice husk, Al2O3, and Fe2O3, in that order by weight percentages of 50%, 20%, 15%, and 15%, respectively. Compression molding with pressures of 10, 20, and 30 MPa and a holding time of 20 min at room temperature was utilized in this study. To evaluate the properties of the obtained specimens, density, hardness, flexural, wear, TGA (thermal gravimetric analysis), and DSC (differential scanning calorimetry) tests were conducted. The research findings show that composite specimens' physical and mechanical properties decrease while the friction coefficient increases with increasing pressure during compression molding. In contrast, the pressure increase did not significantly alter the thermal characteristics of the composite specimens. The BP_10 specimen, fabricated at a molding pressure of 10 MPa, exhibited superior properties compared to other specimens. Density, hardness, flexural strength, coefficient of friction, total residue, Tmax, Tg, and Tc in specimen BP_10 was 1.881 g/cm3, 80.5 shore D, 35.84 MPa, 0.262, 58.67%, 354.87, 285.53, and 497.7°C, respectively.Highlights The demand for natural fiber‐reinforced composites is increasing because more vehicles are on the road. The properties of natural fiber‐reinforced composites are strongly influenced by the pressure applied during compression molding. Results show that compression molding pressure strongly influenced the hardness, density, flexural strength, friction coefficient, and thermal stability of natural fiber‐reinforced composites. The natural fiber‐reinforced composites developed in this research can contribute to several Sustainable Development Goals (SDGs).

“…Finally, cars in Poland are noticeably older than the European average (14 years vs the EU average of 11.5 years). This also means that a higher proportion of cars do not meet the restrictive standards for exhaust emissions, so they have higher emissions and a greater impact on the environment (Wojtyra and Kudłak, 2022).…”

There is mounting evidence that the current model of economic development negatively affects many ecological processes and creates serious threats to the sustainability of economic processes and welfare. In response to those threats, policies have been introduced at supranational and national levels to alleviate the most burning environmental challenges and mitigate their consequences for humanity. At the same time, however, there is a growing understanding that economy–environment relations have to be analysed and approached from a geographical perspective, as this sheds more light on spatial differences and specificities, the unevenness of transition processes and their social consequences as well as the need to perform the transition towards sustainability in a spatially sensitive manner. This article seeks to reconstruct and analyse two processes – urban sprawl and the automobile revolution – that took place in the Polish urban regions during the systemic transformation period and to discuss their potential consequences for the transition to sustainability from a geographical perspective. We show that different places, due to their specificities and legacies, start sustainability transitions from different initial conditions that might affect the pace of this process as well as its environmental and social consequences.
