The development of biodegradable composites has gained significant attention due to the environmental concerns associated with synthetic polymers. Unripe banana starch, characterized by its high amylose content, presents excellent film-forming properties and biodegradability, making it a promising matrix for composite fabrication. Despite these advantages, its poor mechanical properties restrict its standalone use in structural applications. To improve its performance, reinforcement with natural fibres such as pineapple leaf fibres has been explored.
