 Natural fibers have been studied extensively over the past few decades due to their potential to replace traditional synthetic fibers in polymeric composites. This research has focused primarily on the characterization of natural fibers and their comparison with conventional composites in terms of mechanical behavior and application performance. Natural fibers exhibit a wide range of variation in properties depending on the harvesting location and environmental conditions, which makes it challenging to select the most suitable fiber for a given application. Additionally, recent publications have explored new types of natural fibers such as emergent fibers, which offer unique properties and potential applications. Finally, a bibliometric analysis was conducted to assess the current state of natural fibers' applications and identify areas for further development.
