In today's quickly modernizing world, the use of composite materials and environmental pollution, as well as the employment of renewable and biodegradable resources, are intimately related. Finding sustainable materials is the focus of an environmental researcher. Both natural and synthetic fibers come in a variety of shapes and sizes. Recently, natural fibers have attracted the attention of scientists, engineers, and researchers as an alternative reinforcement for fiber-reinforced polymer composites. Because of their low cost, low density, non-toxicity, acceptable mechanical quality, high specific strength, non-abrasive nature, eco-friendliness, and minor waste disposal difficulties, they are utilized to replace more conventional fibers like glass, aramid, and carbon. Researchers have looked into the potential applications of natural fibers in great detail. Other fibers, such as banana, jute, coir, abaca, sisal, straw wheat, rice husk, pineapple leaf fiber, cotton, oats, and bagasse, have grown in importance over the past ten years. The banana (Musa sapientum) plant is a massive herb, a major fruit crop, and an ancient species that is planted all over the world. Bangladesh produces the most bananas in the world. The banana plant also produces banana fiber, a kind of textile fabric, in addition to the delicious fruit. Paper, polymer composite reinforcement, and teabags are a few applications for banana fiber. Banana fiber can be produced from the stems of banana plants, which are native to Southeast Asia and are discarded when the fruit is collected. When banana fibers are utilized as reinforcement, the physical, chemical, and mechanical properties of the polymer composites have greatly improved. The current study provides a thorough investigation of banana fiber reinforced composites and their potential applications. Combining banana fiber with some modern technology will help to reduce waste, boost energy efficiency, and enhance sustainability. In this study, banana fibers are investigated in terms of their utilization, mechanical qualities, and potential applications.
