Abstract

This research aims to develop environmentally friendly brake camoas by utilising banana peel charcoal as filler material, replacing asbestos which is a health risk. Banana peel charcoal was mixed with polyester resin as the matrix, with variations in composition (35% and 45%) and particle size (100 mesh and 200 mesh). The mixing process was carried out carefully to produce a homogeneous and air bubble-free material. Hardness testing was conducted using a Shore D type durometer with five test points on each specimen. The test results showed that the specimen with 35% charcoal content and 200 mesh particle size produced the highest hardness value, 81.2 HD. This indicates that the finer the particle size and the higher the resin content, the denser and harder the material structure. The combination provides optimal mechanical performance, making banana peel charcoal a potential, low-cost, and environmentally friendly alternative brake lining material. Further research is recommended to evaluate the wear properties and thermal resistance for wide application in the automotive industry.
