Green, or biodegradable, composite materials are gaining attraction because they are less harmful to the environment and have the potential to eventually replace traditional composite materials. PLA-based green composites have drawn more and more attention from researchers due to the growing ecological risk and environmental consciousness. Because of its excellent mechanical and thermal qualities, eco-friendliness, biodegradability, and antibacterial qualities, PLA has emerged as the most promising matrix material for sustainable bio composites. These composites have the potential to be more appealing than conventional petroleum-based composites, which are toxic and nonbiodegradable. Due to their cost-effectiveness and lightweight nature, composite materials are widely used in a wide range of applications in the structural, automotive, aerospace, and other household sectors. However, the recycling process of traditional fiber-reinforced plastics frequently poses environmental challenges. The mechanical characteristics of bio composites may be greatly affected by the kind of fiber employed in the fiber/matrix adhesion. Furthermore, the current state of PLA 3D printing with natural fiber reinforcement was outlined, along with its potential in 4D printing for uses of stimuli-responsive polymers. The purpose of this study is to highlight the progress made and investigations completed on bio-composites based on natural fibers and polylactic acid (PLA) during the last decade. The synthesis, biodegradation, properties, methods and possible uses of PLA-derived bio composite materials are all summarized in this article.
