Abstract

This study investigates the development of sustainable composite brake pad materials reinforced with mechanically extracted pineapple leaf fibers (PALF) without chemical processing and aluminum chip waste. The work was motivated by environmental and health concerns associated with conventional friction materials containing synthetic and potentially toxic fibers. A Taguchi L4 design of experiments was employed to evaluate the effects of pineapple leaf fiber length (20 and 40 mm), PALF mass fraction (5 and 7 wt.%), and aluminum chip mass fraction (3.3 and 6.7 wt.%) on tribological performance. Four formulations were fabricated while maintaining the remaining constituent’s constant. The composites were tested using a pin-on-disc tribometer to determine the coefficient of friction and wear mass loss. The experimental data were analyzed descriptively using mean response values, main effects plots, and Delta analysis. The results showed that tribological performance was strongly influenced by formulation. Delta analysis indicated that PALF content had the greatest influence on the coefficient of friction, whereas fiber length most strongly affected wear mass loss. Sample 1 exhibited the lowest wear mass loss (0.0183%), while Sample 4 showed the least favorable overall tribological performance, combining the highest coefficient of friction (0.2308) and wear mass loss (0.0622%). These findings demonstrate the potential of PALF and recycled aluminum chips as sustainable constituents for composite brake pad materials.
