The rising demand for sustainable automotive components has driven advancements in eco-friendly brake pads. This study explores the use of chemically modified Pseudoxytenanthera stocksii (P. stocksii) bamboo rhizomes to enhance mechanical and tribological properties while reducing hydrophilicity. Benzoylated bamboo rhizomes were incorporated into a cardanol-modified polymer matrix with polydimethylsiloxane (PDMS) to develop biodegradable, asbestos-free brake pads. Optimization studies identified the best-performing formulation, C10S8B12, which was rigorously tested using a CHASE tribometer per SAE J866a standards. It achieved a coefficient of friction (0.43 normal, 0.42 hot), minimal wear loss (3.33%), excellent fade resistance (6.67%), and a 102% recovery rate, meeting FF Edge Codes and OEM specifications. Scanning Electron Microscopy confirmed enhanced tribological performance, highlighting modified bamboo rhizomes as a sustainable alternative.
