Development & Tribological Analysis of New Asbestos Free Break Lining Friction Material

Frictional brake lining materials are broadly made of asbestos as their constituent. But asbestosis dangerous for handling due to health hazardous. Asbestos has ample physical, mechanical and tribologicalproperties. The material replacing it should have all these properties with no undermine. In this study on asbestos base and asbestos free brake lining material is presented. Purpose behind this is combine the demeritsof asbestos free and asbestos base materials with comparable properties. Some organic waste from farm like banana peel, palm karnel shell, were also tested for the replacement of asbestos and they found worth throughcomparison with each others. Base on above comparative study a composite material made up of asbestos free brake lining material, can developed to investigate Tribological and Mechanical properties of pista shell. Test set-up is proposed to do that for a drum brake The mechanical and physical properties compare well with commercial asbestos-based friction lining material. Its performance under static and dynamic conditions compare well with the asbestos-based lining material.However, further refinement of the PS liningformulation is recommended in order to have a comparable wear rate at higher vehicular speeds.
