dc.description.abstractIn this research, green composites were produced by reinforcing 30% hemp fiber by weight for the purpose of improving the properties of polylactic acid (PLA) polymer. Surface treatments such as alkali (NaOH) and silane (APTES), different modification methods such as poly (butylene succinate) (PBS) and thermoplastic polyurethane (TPU) blend processes, maleic anhydride (MA) coupling were all employed to improve fiber-matrix interfacial adhesion. Extrusion and injection molding were used to create PLA bio-composites, and their thermal, mechanical, and degrading characteristics were examined. The glass transition and crystallization temperature generally reduced, while the melting temperature and degree of crystallinity increased, according to Differential Scanning Calorimetry (DSC). Reinforcement of hemp fiber increased the tensile strength of all bio-composites. Compared to pure PLA, the tensile strength of N-H/PLA (alkali-treated hemp/PLA) is 54.3%, P-H/PLA (PBS-untreated hemp/PLA) is 24.69% improved the T-H/PLA (TPU-untreated hemp/PLA) had the best elongation at break value due to the TPU polymer’s flexibility. The N-H/PLA bio-composite showed the lowest soil degradability after neat PLA. The S-H/PLA (silane-treated hemp/PLA) offers the highest weight loss value. The FTIR spectra of APTES-treated hemp fibers did not change significantly. The N-H/PLA had the lowest water absorption, while the M-H/PLA (MA- untreated hemp/PLA) had the greatest.
