Abstract
Biodegradable bioplastics are increasingly considered promising alternatives to petroleum-derived plastics because of their reduced dependence on fossil resources and lower environmental impact [1]. However, their broader application remains limited by relatively high production costs and insufficient mechanical performance [2]. Natural plant fibers offer an effective reinforcement strategy, and the combination of fibers with different length scales can form hierarchical networks that improve dispersion, interfacial adhesion, and stress transfer [3]. In this study, jute fibers and microfibrillated cellulose were incorporated into a poly(lactic acid) matrix to construct a hierarchical interfiber network. The resulting foams exhibited improved compressive strength, energy absorption, and sound absorption owing to synergistic interactions between the dual-scale fibers and the polymer matrix. Furthermore, the foams maintained their structural and functional properties after reprocessing, demonstrating their potential as recyclable lightweight materials for structural and acoustic applications.
