  Abstract: This study develops bio-derived polymer composites using a thermoplastic starch–lignin (TPS–lignin) matrix reinforced with alkali-treated coir and plantain fibers for sustainable load-bearing applications. The TPS–lignin matrix was formulated using cassava starch, glycerol, and 10 wt% lignin, while coir and plantain fibers were surface-modified using 5 wt% NaOH to enhance interfacial compatibility. Composite laminates were fabricated with varying fiber loadings (10–40 wt%) through melt-mixing and hot-press compression. Tensile, thermal, morphological, and …
