Asbestos-Free Aluminium Dross Brake Pad: A Mini Review

Asbestos-related materials are avoided due to cancer-causing asbestosis that is a health risk to users. A brake pad that is eco-friendly with the use of aluminium dross industrial waste and epoxy binder is therefore proposed. Various applications of aluminium dross have been explored by researchers with the view of reducing hazardous waste from the environment. Compressive strength, hardness, specific gravity, microstructural analysis, flame resistance, oil, and water absorption, and wear characteristics are significant tests carried out on the brake pad. Waste materials such as banana peel, bagasse, periwinkle shell, palm kernel shell, amongst others, were employed as common additives in the production of the brake pad. Exploring utilizing industrial and agro-waste in the development of a viable brake pad as an alternative to the existing brake pad is therefore reviewed
