Fabrication and Characterization of Asbestos Free Brake Pads Composite using Elaeocarpus Ganitrus as Reinforcement

Abstract

To minimize the potential health hazards, there is a conscious avoidance of using asbestos fiber due to its recognize carcinogenic nature. This research aimed to produce a brake pad composite using elaeocarpus ganitrus seed powder to replace asbestos. The composition of elaeocarpus ganitrus seed powder was varying volume fraction from 8 wt% to 12 wt% with an interval of 2 wt%. The properties of brake pads, including their morphology, physical characteristics, mechanical performance, and wear behavior, were thoroughly investigated and analyzed. The experimental results indicated a positive correlation between the addition of 12 wt% ealeocarpus ganitrus and the observed increase in density and hardness of the produced samples. Moreover, the wear resistance increased with the percentage of elaeocarpus ganitrus increased. The samples containing 12 wt% in elaeocarpus ganitrus seed powder gave better properties compared with other sample composites. The research finding suggests that elaeocarpus ganitrus particles can be a viable alternative to asbestos in the manufacturing of brake pads.
