ABSTRACT

Due to the increased public awareness in ensuring a sustainable and long-lasting world, both academic and industrial researchers are trying to use eco-friendly and biodegradable materials in every sphere of life. Petroleum-based synthetic materials are nonrenewable, hazardous, and costly. In contrast, natural fibers are mainly derived from plant-based sources, which are recyclable, renewable, sustainable, abundantly available, and cheap. Hence, the use of natural fibers in the fabrication of composite materials is increasing dramatically. These are used as a reinforcement with the polymer matrix to fabricate the composites. Although a massive amount of research works has been performed to develop green composites, until now the composite fabrication process is facing some terrific problems such as the lower adhesion tendency of the composites, due to the presence of the hydrophilic natural fibers and hydrophobic polymer matrix. Researchers are trying to find out the optimum combination of the composites that can be able to exhibit excellent mechanical properties for the application areas where greater strength is a must. This review is focusing on the composite materials fabricated from the bast fibers, a branch of the natural fibers, with various thermoplastic and thermosetting polymers, and their potential application areas.

摘要

由于公众对确保可持续和持久世界的认识不断提高，学术界和工业界的研究人员都在努力在生活的各个领域使用环保和可生物降解的材料。石油基合成材料不可再生、危险且昂贵。相比之下，天然纤维主要来源于植物来源，它们具有可回收、可再生、可持续、资源丰富且价格低廉的特点。因此，天然纤维在复合材料制造中的使用正在急剧增加。它们用作聚合物基体的增强材料以制造复合材料。尽管已经进行了大量的研究工作来开发绿色复合材料，但到目前为止，复合材料的制造过程还面临着一些可怕的问题，例如复合材料的粘附性较低，由于亲水性天然纤维和疏水性聚合物基质的存在。研究人员正试图找出复合材料的最佳组合，以便能够在需要更高强度的应用领域表现出优异的机械性能。本综述的重点是由韧皮纤维（天然纤维的一个分支）与各种热塑性和热固性聚合物制成的复合材料及其潜在应用领域。
