Alkali treated coir/pineapple leaf fibres reinforced PLA hybrid composites: Evaluation of mechanical, morphological, thermal and physical properties

Natural fibre plastic thermosets or thermoplastics composites are promising and sustainable green materials to achieve durability without the utilization of toxic chemicals Currently, the most commonly used agricultural by-products or agricultural-waste materials as reinforcement includes most of the cereal stalks, rice husks, bagasse, coconut fibres, corn cobs, nutshells and other wastes might alleviate the defined shortage Natural fibres such as coir fibres (CF) and pineapple leaf fibres (PALF) are interesting reinforcement in a composite system due to their specific properties such as low density, lightweight and non-abrasiveness during processing. In addition, they are low cost, renewable, biodegradable and abundantly available CF (Cocos nucifera) is known as versatile lignocellulosic fibres and is currently broadly being used in diverse indus-
