Abstract

A suitable selection of a filler material enhances the mechanical and tribological characteristics of brake friction material. There are various types of fillers like organic, inorganic, metallic and natural fibres. Among these various types, metallic fillers are very important as they consist of different functional characteristics of brake friction material. Hence in this work, four friction composites are shown with identical parent composition (65 wt%) and varying steel powder from 0 wt% to 12 wt%, and barite from 35 wt% to 23 wt%, respectively in each composition, i.e., S0, S1, S2 and S3. All these four composites are characterised for physical and mechanical properties according to Indian Standards (IS). The coefficient of friction is investigated using a pin on disc tribometer. Finally, the correlation between physical properties and coefficient of friction is determined. It is concluded that inclusion of steel powder improved almost all the physical and mechanical properties. It is also observed that density, void content and hardness influence the coefficient of friction level.

钢粉填充盘式制动器摩擦材料物理力学性能试验研究

选择合适的填充材料可以提高制动摩擦材料的机械性能和摩擦学性能。填料有多种类型，如有机、无机、金属和天然纤维。在这些类型中，金属填料是非常重要的，因为它们构成了不同的制动摩擦材料的功能特性。因此，在这项工作中，四种摩擦复合材料显示了相同的母成分(65%重量%)，不同的钢粉从0重量%到12重量%，重晶石从35重量%到23重量%，分别在每种成分中，即S0, S1, S2和S3。所有这四种复合材料的物理和机械性能都符合印度标准(IS)。采用针盘式摩擦计对摩擦系数进行了研究。最后，确定了物理性能与摩擦系数之间的关系。结果表明，钢粉的加入改善了合金的所有物理力学性能。密度、孔隙率和硬度对摩擦系数也有影响。
