“…Some of the applying pressing pressure, pressure heat, sort are given in the table 1 bellow. 100Mpa 160°C [20] 100bar 150°C [8] 50-100-200-300 Mpa 150°C [21] In this study the braking pad consists of barite, phenolic resin, glass fiber, coal and juniperus drupacea nut powder (JDNP). The effect of the formed pressures on the hardness, friction coefficient, density and wear rate of different pressing pressures were investigated by changing the pressing pressures to 100, 150 and 200 MPa, which are considered to affect the properties of the starting material.…”

In this study, samples which can be used as brake pads are prepared. A mixture of 50% barite by mass, 20% glass fiber, 25% phenolic resin and 5% coke powder was prepared, and 6 samples were prepared by adding juniperus drupacea nut powder (JDNP) at 10%, 25% and 40%. The samples were produced in 3 different mixing times, 2 different compaction times, 3 different compaction temperatures and 3 different compression pressures. The effect of the compression pressure on the wear rate, hardness, density and cold friction coefficient was investigated. The wear rate ranges from 0.093.10 -7 -4.235.10 -7 cm 3 .N -1 .m -1 . The coefficient of cold friction ranges from 0.30 to 0.48. The density is between 1.82-2.17g/cm 3 . The hardness values are from 85 to 117 according to the Rockwell R scale. Wear rate and cold friction coefficient values are in accordance with TS 555 standard. It has been determined that the compressive pressure is most affected by the hardness and friction coefficient. Generally, rise of pressure reduces hardness and friction coefficient. The effect of density on JDNP ratio is opposite.

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).
