Optimization of eggshell particles to produce eco-friendly green fillers with bamboo reinforcement in organic friction materials

Abstract The environment is a very important topic today as well in the future. One source of air pollution that has potential to harm health wear particles released by vehicle braking systems. If these come from hazardous materials, they could destroy human and environment. Based on conditions, exploring more environmentally friendly materials substitute friction necessary. In this study, brake linings were prepared bamboo fiber eggshell (ES) with various pre-treatment conditions. composition material frictions consisted phenolic resin, fiber, particles, ES zinc, alumina, graphite following: 35% 10% graphite, alumina powder, 5% zinc 30% ESs. This study focused observing mechanical tribological behavior when using fillers. There are three stages manufacturing material: cold press, hot heat treatment. optimization characteristics ESs organic was carried out Taguchi method analyzed data envelopment analysis-based ranking (DEAR). An interesting finding calcined at 900°C for 120 min, particle size 200 mesh, volume fraction 25% resulted most optimal lining performance. Calcination min completely changed CaCO 3 phase CaO. also shows have be developed two-wheeled vehicles produced exhibited hardness, coefficient friction, specific rates 92.82 HR, 0.32, 4.43 × 10 −6 mm ·N −1 ·m , respectively.
