Plant fibers,composed of carbohydrates,phenolic substances,and terpenes,take the form of fibrous or fluffy strands,exhibiting a wide range of varieties and abundant resources.These fibers possess the advantages of high specific strength,biodegradability,and renewability,making them a sustainable source of natural green bio-mass.Utilizing plant fibers as reinforcement materials in resin-based composites not only facilitates the efficient and valuable use of plant fiber resources,thus enhancing the comprehensive application performance of com-posites,but also contributes to cost reduction in composite manufacturing.In recent years,research into various types of plant fiber-reinforced biodegradable composites has attracted considerable attention.This paper reviews the latest advancements in plant fiber reinforcement in three biodegradable polymer matrices:Polylactic acid(PLA),poly(butylene adipate-co-terephthalate)(PBAT),and poly(butylene succinate)(PBS).It provides an analysis and comparison of the overall performance of these different composites,offering insights into their application potential and forecasting future trends.
