Abstract

GREEN REINFORCEMENTS IN FRICTION MATERIALS: THE CASE OF EGGSHELL PARTICULATES IN NON-ASBESTOS BRAKE PADS

ABSTRACT

As the automotive industry transitions toward environmentally sustainable technologies, there is a growing need to replace hazardous materials in critical components such as brake pads. This study examines the reliability and environmental sustainability of non-asbestos brake pads reinforced with eggshell particulates (ESPs), a biodegradable, calcium carbonate-rich waste material. Considering the health and environmental hazards associated with asbestos, there is a growing demand for safer, eco-friendly alternatives in friction materials. Composite formulations incorporating ESPs of 20 μm, 25 μm, and 30 μm particle sizes were developed to evaluate their effects on key performance metrics, including wears resistance, hardness, and long-term reliability. The results reveal that brake pads reinforced with 20 μm ESPs demonstrated superior hardness and wear resistance, achieving a 94% reliability rating over one year of simulated use. These findings highlight the potential of ESP-based composites as sustainable, high-performance alternatives for automotive braking systems, offering both environmental and functional benefits.
