Optimization of Process Parameter in the development of Ecofriendly Brake-pad from Coconut Fruit Fiber (Coir L.) And Oyster Sea Shells (Magallana-Gigas L.)

Abstract

Coconut Fruit Fiber, CFF, and Oyster Sea Shells, OSS were gathered from the waste peel and suspended in a solution of sodium hydroxide (NaOH) for about 12h in other to eliminate unwanted remnants. Dried CFF and OSS were grounded to powder using an electric grounding machine. Thereafter sieved to 75, 125, and 175µm grain sizes. The based materials, CFF and OSS were prepared into organic-based brake pads by compressive molding with different formulations of base materials, epoxy resin, hardener, graphite friction modifiers, and copper chips. A commercially bought brake pad was used for evaluation in this research. The characterization of the brake pad produced is mostly influenced by molding pressure and grain sizes, respectively. Hence, the density, hardness, tensile strength, and compressive strength values were reduced with a rise in grain sizes. In conclusion, the ideal values of all responses fall within the normal desires of brake pads as they matched positively with commercial lining material. Thus, the characterization of the developed friction lining links suitably and is proficient in creating fewer sounds during the application of braking, owing to its high mechanical properties. Therefore, coconut fruit fibers and oyster sea shells can be a conceivable replacement for asbestos friction brake lining manufacture.
