N2 - The paper addresses the potential application of jute fibers in combination with powderized hazelnut shells as natural and biodegradable fillers in non-asbestos organic (NAO) friction composites. Two groups of the samples, based on a combination of jute fibers and graphite as a solid lubricant, and the jute containing samples where graphite is replaced with hazelnut shells, were prepared. Friction-wear properties of the prepared samples were evaluated using the CHASE tester according to the SAE J661 recommendation. The friction-wear tests revealed the jute with graphite samples to show significant fade phenomenon if the temperature during the second fade test increases above 300. °C. The samples belonging to the jute with hazelnut shells group show better resistance against the fade phenomenon even at temperatures higher than 300. °C. Based on the comparison of the overall friction performance, the composite with 5.6. vol.% of jute fibers and 8.4. vol.% of powderized hazelnut shells (assigned as JH-5.6) was selected as the best performing, and this composite contains 14. vol.% of natural, renewable and biodegradable components. If we accept that the maximum temperature during braking will be up to 290. °C then the composite with 23.6. vol.% of jute fibers and 6.3. vol.% of powderized hazelnut shells (assigned as JH-23.6) shows an acceptable stability of the friction coefficient, whereas this composite contains almost 30. vol.% of natural, renewable and biodegradable components.
