“…Because of these properties, processes and applications utilizing natural fibers as reinforcement for plastic composites have been increasingly studied by many researchers in recent years [3][4][5]. In previous studies by our research group [6,7], both silk paper-and silk/ bamboo paper-reinforced poly(butylene succinate) (PBS) green composites have been developed using waste silk, and the corresponding mechanical properties have been studied in detail. Papermaking results in a network structure containing an improved distribution of short fibers, aiding connectivity between the fibers.…”
