Brake friction materials (BFMs) have a critical role in ensuring the safety as well as the reliability of automotive braking systems. However, traditional BFMs, typically made from asbestos, are associated with environmental and health concerns. Therefore, this results in a growing interest in developing alternative BFMs that are eco-friendly, sustainable, and cost-effective. This study investigates the effect of varying concentrations of epoxy, rice husk, alumina (AlO), and iron oxide (FeO) on the mechanical and thermal properties of BFMs prepared using the hand layup method. In this study, the rice husk, AlO, and FeO were filtered through a 200-mesh sieve. Note that the BFMs were fabricated using different combinations and concentrations of the materials. Their mechanical properties, such as density, hardness, flexural strength, wear resistance, and thermal properties, were investigated. The results suggest that the concentrations of the ingredients significantly influence the mechanical and thermal properties of the BFMs. A specimen made from epoxy, rice husk, AlO, and FeO with concentrations of 50 wt.%, 20 wt.%, 15 wt.%, and 15 wt.%, respectively, produced the best properties for BFMs. On the other hand, the density, hardness, flexural strength, flexural modulus, and wear rate values of this specimen were 1.23 g/cm, 81.2 Vickers (HV), 57.24 MPa, 4.08 GPa, and 8.665 × 10 mm/kg. In addition, this specimen had better thermal properties than the other specimens. These findings provide valuable insights into developing eco-friendly and sustainable BFMs with suitable performance for automotive applications.
制动摩擦材料（BFMs）在确保汽车制动系统的安全性和可靠性方面起着关键作用。然而，传统的制动摩擦材料通常由石棉制成，存在环境和健康问题。因此，人们越来越关注开发环保、可持续且具有成本效益的替代制动摩擦材料。本研究调查了不同浓度的环氧树脂、稻壳、氧化铝（AlO）和氧化铁（FeO）对采用手糊法制备的制动摩擦材料的力学和热性能的影响。在本研究中，稻壳、AlO和FeO通过200目筛网过滤。请注意，制动摩擦材料是使用不同的材料组合和浓度制造的。研究了它们的力学性能，如密度、硬度、弯曲强度、耐磨性和热性能。结果表明，各成分的浓度对制动摩擦材料的力学和热性能有显著影响。由浓度分别为50 wt.%、20 wt.%、15 wt.%和15 wt.%的环氧树脂、稻壳、AlO和FeO制成的试样产生了制动摩擦材料的最佳性能。另一方面，该试样的密度、硬度、弯曲强度、弯曲模量和磨损率值分别为1.23 g/cm、81.2维氏硬度（HV）、57.24 MPa、4.08 GPa和8.665×10 mm/kg。此外，该试样的热性能优于其他试样。这些发现为开发具有适合汽车应用性能的环保和可持续制动摩擦材料提供了有价值的见解。
