Innovative Recycling of Asbestos Waste: Reinventing Brake Pad Materials to Boost Automotive Components
Main Article Content
Abstract
When a brake shoe makes contact with the brake drum, a friction substance called a brake lining is connected to the surface of the brake shoe to generate frictional force. Previously, asbestos was the most commonly utilized material for brake linings. Alternative materials, however, have been developed in response to the health dangers involved with inhaling asbestos dust. Non-asbestos fibers, for example, have seen significant use in braking components. Semi-metallic, non-asbestos organic (NAO), low-metallic NAO, and ceramic brake pads are the four basic varieties offered. It is critical to determine which type is best for your vehicle. Paper, elastomerics, graphitics, and sintered metals are among the friction materials used. A variety of other materials, including ceramics, advanced fibers, and other metal alloys, are also used. Prior to its ban, asbestos was widely utilized as a friction substance. Natural minerals found in rock formations are used to make asbestos fibers. These minerals exist as strong, flexible fibers that can be split into individual strands and thin threads. These threads can be woven into high-temperature and chemical-resistant textiles.The goal of this study is to recycle old asbestos materials into practical commercial products with unique properties. Asbestos waste powder will be incorporated into particle-reinforced aluminum composites. The sintering processes improve mechanical strength and wear resistance by forming a metallic structure. Waste asbestos materials, whether in the form of fine powder or bigger particles, can be used to make new goods. Asbestos' intrinsic brittleness makes it appropriate for powder sintering to produce tile formations or acoustically orientated materials. This recycled waste product has applications such as layer creation in 3D printing and reinforcement in composite manufacturing processes. In addition, fracture surface analysis was performed as part of the technique.
