Carbon-natural fibre hybrid composites are emerging as promising candidates for lightweight prosthetic socket structures due to their favourable strength-to-weight ratio and sustainability. In this work, carbon-flax and carbon-kenaf hybrid laminates were fabricated using a vacuum-assisted hand lay-up process and evaluated under dry sliding wear conditions. Tribological experiments and FESEM characterization were performed to investigate the influence of operating parameters and the associated wear mechanisms. Statistical analysis revealed that sliding speed was the dominant factor affecting wear behaviour, accounting for approximately 60% of the total variation, followed by sliding time (~26%) and applied load (~12%). FESEM examination showed matrix cracking, debris accumulation, and material removal on severely worn surfaces, whereas optimized laminates exhibited comparatively smoother surfaces and improved surface integrity. The results demonstrate the potential of carbon-natural fibre hybrid composites for enhancing the durability and wear performance of prosthetic socket materials.
