Experimental investigation on the friction characteristics of hazelnut powder reinforced brake pad

After the realization that asbestos fiber is harmful to human health, efforts produce organic and environmentally friendly brake pads have increased. In this study, an pad (NUS sample) was produced with addition of 3.5% hazelnut shell powder. Hardness density measurements sample were made. Chase type device used for wear friction tests. The experiments done according SAE J661 standard. average coefficient value obtained as a result found be 0.435 µ. Bu de?er standartlara uygundur ve “FF” s?n?f? aral???ndad?r. This complies standards in "FF" class range.
