Abstract
This experimental study aimed to assess the friction performance of nonasbestos organic (NAO) brake pad based on ternary combinations of rockwool, PAN, and cellulose fibers under fade-recovery conditions. Four compositions with varying volume fractions of rockwool, PAN, and cellulose fibers were fabricated. The tribological properties of the sample were tested using JF160 Chase tester based on SAE J661. Optimally, the sample with a synergistic combination of rockwool, PAN, and cellulose fibers in proportion of 10:4:4 vol.% exhibited the best overall friction performances. This combination could be used as NAO brake pad material for reliable, efficient, safe, and comfortable braking operations.
