Performance comparison between boron and alumina brake pad

This study proposed Boron as an alternative to Alumina in the brake pad composition. Specifically, it examined effects of Boron on the brake pad performances including friction coefficient, wear resistance, hardness, porosity and specific gravity at four different levels which are 0.6wt%B, 1.0wt%B,...

Specifically, it examined effects of Boron on the brake pad performances including friction coefficient, wear resistance, hardness, porosity and specific gravity at four different levels which are 0.6wt%B, 1.0wt%B, 1.5wt%B and 2.0wt%B. The performance of Boron mixed brake pads, in addition to their wear characteristics were also compared with the conventional brake pad consisting Alumina (AI2O3) respectively using scanning electron microscope(SEM) and surface roughness machine. A total of 20 samples were prepared to perform friction and wear test, 25 samples for hardness, porosity and specific gravity test respectively and 15 samples prepared for surface roughness test. It was found that friction coefficient of Boron mixed brake pads and commercial brake pad were significantly different during the CHASE test. Thickness loss for commercial brake pad sample was the highest compared to all Boron mixed brake pads. Thickness loss for the latter generally reduced with the increase in Boron content, with ZMF + B l . 5 % showed the best wear resistance. In summary, ZMF + B l . 5 % is considered as the best formulation among all formulations for its high friction coefficient value, low thickness loss, high hardness, constant porosity and specific gravity value. 2011-02-21T07:28:20Z 2011-02-21T07:28:20Z 2009-02 Thesis http://hdl.handle.net/123456789/673 en application/pdf application/pdf Fakulti Sains dan Teknologi
