- Abstract
- This study investigated particulate matter (PM) produced during brake application, focusing on the effect of space fillers in low-steel friction composites. The composites ranked in terms of brake emissions in a descending order were BaSO4, Ca(OH)(2), and CaCO3. CaCO3 produced thicker friction films on the steel fibres than Ca(OH)(2), whereas bare steel fibres were found with BaSO4, indicating strong effects of the filler-dependent coverup layers, which was confirmed by microhardness tests. The filler effect on PM suggests that proper selection of space fillers can reduce brake emissions from grey iron discs by preventing direct adhesion with steel fibres.
