Evaluasi Sifat Kekerasan Kampas Rem Biokomposit Sebagai Alternatif Non-Asbestos

Abstract

Brake pads play a crucial role in the safety system of motor vehicles due to their function in slowing down or stopping the vehicle. The use of asbestos as the primary material in brake pads has been associated with negative impacts on health and the environment, necessitating the development of safer and more sustainable alternatives. This study investigates the mechanical properties of biocomposite-based brake pads made from banana peel and rice husk waste, with polyester resin as the binding matrix. The filler materials were processed into fine charcoal with a particle size of 100 mesh and mixed using the hand lay-up method with specific volume fraction variations. Hardness testing was conducted using a Shore D durometer in accordance with ASTM D2240 standards. The obtained data were analyzed quantitatively using the ANOVA method through Minitab Statistical software. The test results indicated that variations in the composition of filler materials had a significant effect on the hardness value of the brake pads. These findings suggest that biocomposites made from organic waste have potential as environmentally friendly alternatives to non-asbestos brake pads.
