Investigation of usability of marble waste in automotive brake pads manufacturing

Brake linings used in automotive disks are usually composed of various components. Expected properties from a brake lining are appropriate standart value of wear resist, friction coefficient and also economical value. Brake lining extremely warms up during braking due to friction. The braking performance of brake lining changes and braking lining is subject to mecanical deformation due to excessive temperature.In this study, it is aimed to revaluate the waste of marble dust in marble processing in Turkey. For this purpose, marble wastes are grinded to produce marble dust. Dust wastes of marble is used as filler material in brake pads. The brake lining, which has new formulation, is produced by using various additive materials. Metallic particles, granite powder, marble dust and barite are added to brake lining components to improve brake lining properties. Marble dust is used to produce brake pad in different ratios. Therefore, the effect of marble dust on braking performance is investigated. It is observed that favorable results in braking performance is obtained using of marble dust. In the light of this results, the use of marble dust in brake pad is important in view of both revaluation of marble wastes and decreasing cost of manufacturing.
