Development of Ecofriendly Automobile Brake Liner using Different Grades Sizes of Pulverized Cow Hooves Powder
Main Article Content
Abstract
This paper presents the research on novel brake lining alternative materials. Asbestos has long been used as brake lining for automobiles for its exceptional physical and elemental properties. However, handling it is hazardous to one's health; therefore, its use has declined, paving the way for other substitutes. By application of materials such as cow hoof dust, epoxy, barium sulphate, graphite and Al2O3, an asbestos-free brake lining was created in this experiment. Three grades of sieves were created from the cow hooves: 106μm, 355μm and 660μm. Using a compression moulding process, the sieved cow hooves were employed in the creation of brake liner in a ratio of 25% cow hooves, 10% barium sulphate, 5% graphite, 10% aluminium oxide and 50% epoxy resin. Microstructure analysis, water absorption, density, hardness, compressive strength and wear rate are looked at. The outcomes demonstrated that the better the characteristics, the finer the sieve size. After the outcomes of this study were contrasted with those of commercial brake pads made of asbestos, a strong correlation was seen. Therefore, cow hooves can be utilised to make brake liners devoid of asbestos.
