The ever-burgeoning sustainable need for humanity to produce lighter, tougher, and more cost-effective materials has led to the development of biodegradable composites. Ever since their creation, natural fiber-based composites have found themselves ubiquitous. Due to their exceptional performance, Natural fiber-reinforced composites have been predominantly used in several engineering applications. Coconut leaf sheath (CLS) is an abundantly available agro-waste that can be easily extracted from the coconut tree. This review investigates the potential of incorporating coconut sheath into polymeric matrices. Also, the effects of surface treatments, synthetic fiber hybridization, and nanofiller-modified matrices were analyzed in detail. It has been observed that surface modification of coconut sheath, hybridization with other natural or synthetic fibers, and nanofiller-modified polymeric composites exhibit better mechanical performance compared to monolithic coconut sheath-based polymeric composites. One of the key advantages of hybrid composites is that they can combine the strengths of different constituents to overcome their individual limitations. Moreover, coconut sheath-based hybrid composites enhance the composites' damage tolerance and reduce the material cost.
人类对生产更轻、更坚固且更具成本效益材料的持续增长的可持续需求，推动了可生物降解复合材料的发展。自天然纤维基复合材料问世以来，它们已无处不在。由于其卓越的性能，天然纤维增强复合材料已主要用于多种工程应用中。椰叶鞘（CLS）是一种大量可得的农业废弃物，可轻松从椰子树上获取。本综述研究了将椰鞘纳入聚合物基体的潜力。此外，还详细分析了表面处理、合成纤维杂交和纳米填料改性基体的影响。据观察，与基于单一椰鞘的聚合物复合材料相比，椰鞘的表面改性、与其他天然或合成纤维的杂交以及纳米填料改性的聚合物复合材料表现出更好的机械性能。混杂复合材料的关键优势之一在于，它们可以结合不同成分的优点以克服其各自的局限性。此外，基于椰鞘的混杂复合材料提高了复合材料的损伤容限并降低了材料成本。
