The additive manufacturing process of chicken feather fiber (CFF) filled polybutylene succinate (PBS) biopolymer, a sustainable 3D printing process using fully biodegradable and biocompatible polymers that are reinforced by animal-based short fibers reclaimed from agricultural wastes, is studied in this research. The protein-based natural fibers from one of the most abundant agri-wastes in the U.S. are implemented as a filler into the PBS biopolymer to improve its properties and lower the cost of the biocomposite material while maintaining the full biodegradability and biocompatibility of the 3D printed structures. In this paper, different weight percentages of ground CFF were added to the PBS polymer to make 3D printable filaments, and these custom-made filaments were loaded into an FDM 3D printer to print test specimens. The tensile and flexural properties of the CFF/PBS biocomposites are measured, compared, and analyzed. SEM imaging was also performed on the cross sections of failed tensile test specimens to characterize the matrix, fiber, and fiber-matrix interfaces. Finally, thermogravimetric analysis was performed to investigate the impact of the CFF addition on the thermal stability of the PBS polymer.

摘要

The additive manufacturing process of chicken feather fiber (CFF) filled polybutylene succinate (PBS) biopolymer, a sustainable 3D printing process using fully biodegradable and biocompatible polymers that are reinforced by animal-based short fibers reclaimed from agricultural wastes, is studied in this research. The protein-based natural fibers from one of the most abundant agri-wastes in the U.S. are implemented as a filler into the PBS biopolymer to improve its properties and lower the cost of the biocomposite material while maintaining the full biodegradability and biocompatibility of the 3D printed structures. In this paper, different weight percentages of ground CFF were added to the PBS polymer to make 3D printable filaments, and these custom-made filaments were loaded into an FDM 3D printer to print test specimens. The tensile and flexural properties of the CFF/PBS biocomposites are measured, compared, and analyzed. SEM imaging was also performed on the cross sections of failed tensile test specimens to characterize the matrix, fiber, and fiber-matrix interfaces. Finally, thermogravimetric analysis was performed to investigate the impact of the CFF addition on the thermal stability of the PBS polymer.
