| Abstract: | The growing demand for ecofriendly brake friction materials has accelerated research into green alternatives to conventional hazardous components such as asbestos. This study examines novel hybrid composites with permanganate (KMnO4)-treated Alpinia galanga (A. galanga) stem fibers and Pseudoxytenanthera stocksii (P. stocksii) bamboo rhizomes as reinforcement, combined with Metapenaeus dobsoni (M. dobsoni) shrimp-shell powder as a functional filler. The treated natural fibers enhance structural integrity and thermal stability, while the shrimp-shell powder contributes to controlled abrasiveness and improved surface interaction, together tailoring the composite's frictional and wear performance for brake applications. Three composite variants were evaluated, with AGSSC (A. galanga-P. stocksii -Shrimp shell composite) exhibiting superior density (1.52 g/cm3), lower void content (2.56%), higher hardness (89 HRL) (measured by Hardness Rockwell L-scale), coefficient of friction (0.39–0.38), and 26% lower wear rate. The study directly supports SDG 12: Responsible Consumption and Production by upcycling multiple waste resources, including M. dobsoni shrimp shells as bio-fillers, P. stocksii Bamboo rhizome residues, and discarded A. galanga stems from medicinal plant processing, into high-performance friction composites. This approach promotes circular resource use, reduces dependence on non-renewable and non-recyclable materials, and demonstrates a sustainable pathway for developing eco-friendly brake friction materials.
