Asbestos-Free Brake Lining Material Using Sea Shell

Abstract

Due to the extreme health concerns associated with asbestos-based brake linings, researchers are looking at using ecologically friendly bio-based biomaterials as reinforcing agents in composite materials used to make brake pad linings. The goal of this study is to see whether using sea shell (SS) powder in the production of asbestos-free brake lining materials is feasible. The powders were combined with the necessary fillers to make the brake lining. The reinforcing powders compositions were varied between 20% and 35%, the resin binder s composition was changed between 58 and 43 percent, and the filler metal and curing agents compositions were kept constant. These ingredients were weighed, prepared, combined, cured, and moulded. The composite materials were tested for water and oil absorption, compressive strength, hardness, and wear. According to the findings, increasing the quantity of reinforcing components increases the water and oil absorption of the samples. With the addition of up to 35% content, the composite s compressive strength increased proportionally. The tested coefficient of friction was found to be within acceptable limits. Furthermore, when mixed with other fillers and restricted, SS powder has showed tremendous promise in the production of brake linings.
