Presently, scientists and researchers are in an endless quest to develop green, recyclable, and eco-friendly materials. Natural fibre reinforced polymer composites became popular
among materialists due to their lightweight, high strength-to-weight ratio, and biodegradability.
However, all-natural fibre reinforced polymer composites are not biodegradable. Polymer matrices like poly-lactic acid (PLA) and poly-butylene succinate (PBS) are biodegradable, whereas
epoxy, polypropylene, and polystyrene are non-biodegradable polymer matrices. Besides biodegradability, PLA has been known for its excellent physical and mechanical properties. This review
emphasises the mechanical properties (tensile, flexural, and impact strengths) of natural fibrereinforced PLA composites. Factors affecting the mechanical properties of PLA composites are
also discussed. It also unveils research gaps from the previous literature, which shows that limited
studies are reported based on modeling and prediction of mechanical properties of hybrid PLA
composites reinforcing natural fibres like abaca, aloe vera, and bamboo fibres.
