简介
In this paper, a novel hybrid AHP (analytic hierarchy process)-SAW (simple additive weighting) evaluation approach was proposed to select the preeminent brake friction composite formulation. Therefore, brake friction formulations containing varying amount (5–20 wt%) of natural fiber (ramie and hemp) were fabricated and tribo-evaluated on a Chase machine following IS 2742 (part 4). The experimental results such as performance coefficient of friction, fade-%, wear, recovery-%, friction fluctuations, stability and variability coefficient were taken as attributes for the performance assessment. The friction composites NF-1 reinforced with 5 wt% ramie fiber exhibit highest coefficient of friction, lowest fade-% with least friction variability and fluctuation. The composite NF-4 (containing 20 wt% ramie fiber) exhibited the highest recovery-% among all evaluated composites. Moreover, the friction composite NF-5 with 5 wt …
