Abstract

Abstract Considering the emerging importance of a sustainable green environment today, this study contributed to realizing resource sustainability by expanding the use of natural materials in the brake pad sector. Brake pads used in vehicle applications were developed using natural components, and their effects on brake performance properties were observed in brake pad samples containing four different amounts of natural components with additive rates of 0 %, 4 %, 8 %, and 12 %. Tests were conducted on the pad tester to determine the samples’ friction coefficient and wear rates. Hardness measurements were made with a Shore D measuring device. Average and maximum disc roughness were measured to determine the effect of brake pads on the brake disc. Microscopic analyses were performed with a scanning electron microscope. The results showed that using tamarind seed powder in the pad content created a synergy with alumina, brass powder, and graphite as friction modifiers, and the friction coefficient increased slightly. Considering the emerging importance of a sustainable green environment today, it has been determined that using natural materials contributes to realizing resource sustainability by expanding its application in the brake pad sector and positively affecting the brake system disc roughness.

混合动力汽车制动片的摩擦、磨损和硬度特性以及对制动盘粗糙度的影响

摘要考虑到当今可持续绿色环境的重要性，本研究通过扩大天然材料在刹车片领域的使用，为实现资源的可持续性做出了贡献。使用天然成分开发了车辆应用中使用的刹车片，并在含有 0 %、4 %、8 % 和 12 % 四种不同添加量天然成分的刹车片样品中观察了它们对刹车性能特性的影响。在刹车片测试仪上进行了测试，以确定样品的摩擦系数和磨损率。使用邵氏 D 测量仪测量硬度。测量了制动盘的平均和最大粗糙度，以确定制动片对制动盘的影响。使用扫描电子显微镜进行了显微分析。结果表明，在刹车片中添加罗望子粉与氧化铝、黄铜粉和石墨作为摩擦改进剂可产生协同作用，摩擦系数略有增加。考虑到当今可持续绿色环境的重要性，使用天然材料可扩大其在刹车片领域的应用，并对制动系统盘面粗糙度产生积极影响，从而有助于实现资源的可持续发展。
