Abstract
Purpose
The purpose of this study is to investigate the potential of fly ash in automotive brake lining materials.
Design/methodology/approach
Three brake linings containing fly ash (36, 41 and 46 Wt.%) were designed and produced by dry-mixing, pre-forming and hot pressing. The surface hardness of all brake lining samples was measured by using Brinell hardness tester. The density of the specimens was determined based on Archimedean principle in water. The friction and wear characteristics of the brake lining samples were determined using a real brake disc-type tester. Detailed examinations on the worn surface were analyzed using a scanning electron microscopy.
Findings
Fly ash can be good alternative as space filler to reduce the cost for brake lining.
Originality/value
The present study has successfully demonstrated that there is a high potential for commercial applications of brake linings including fly ash as a filler.
