Tensile strength, wear characteristics and numerical simulation of automotive brake pad from waste-based hybrid composite

Abstract

Environmental impact of asbestos brake pad and negative impact on human health has been a real concern for years because the first generation of composites materials had relied heavily on asbestors reinforced composites. The aim of this work is to develop banana peel composite, test its mechanical and wear properties. On this study, a composite material made up of banana peel powder with carbon. Composition 1 increased in both stress and elongation to the maximum output stress of 2.1 MPa and elongation of approximately 13.0. Despite decrease in the weight percent of the carbon powder, the stress output decreased by 14.3% with composition 2 and likewise for composition 3 to approximately 1.40 MPa. Composition 1 experienced minimal loss of weight. This was concluded to be due to influence of the strength on the weight differentials. Composition 1 with minimal loss of weight would be applicable for the brake pad application. It is equivalent to 60% loss of weight in composition 2 and 67.7% loss of weight was experienced in composition 3 compared to composition 1. The results gotten were in correlation with the natural composite materials investigated for brake pad application by previous researchers. With directional heat flux (maximum) value of 604. 24 W/m2 recorded for the specified areas of the produced composites. As the boudary conditions were applied, the equivalent strain from the numerical simulation was 0.003174 m/m. Around the regions with bolt fixing, the numerical simulation gave 1.429 × 10−7 Pa equivalent stress (Maximum). Though there was less stress around the remaining parts.
