PRODUCTION AND TRIBOLOGICAL EVALUATION OF BRAKE PAD MADE FROM LOCALLY AVAILABLE MATERIALS

Abstract

This study explores the design and production of environmentally sustainable automobile brake pads using locally sourced and renewable materials. Cow horn and palm kernel shells, known for their non-toxic properties, were selected as primary base materials, while epoxy resin with hardener functioned as a binder. Additionally, iron filings were incorporated as a reinforcement agent, and graphite powder was included to enhance lubrication. The developed composite brake pads were subjected to comprehensive physical, mechanical, and tribological property evaluations to determine their suitability for automotive applications. Key parameters such as density, compressive strength, and wear resistance were analyzed, with results demonstrating that brake pads produced from locally available materials exhibited promising properties.Among the tested formulations, the sample comprising 40% cow horn, 25% palm kernel shell, 5% graphite, 10% iron filings, and 20% epoxy resin with hardener yielded the most favorable performance metrics, including optimal density and compressive strength, as well as minimal wear rate. These findings highlight the potential of integrating agricultural and animal byproducts into advanced material design, providing an eco-friendly and cost-effective alternative to conventional brake pads while addressing environmental and health concerns associated with asbestos. This study underscores the viability of sustainable materials for high-performance automotive applications and contributes to the growing body of research on green composite materials.
