The Use of Agricultural Waste in the Modification of Poly(lactic acid)-Based Composites Intended for 3D Printing Applications. The Use of Toughened Blend Systems to Improve Mechanical Properties

The presented research focused on improving the mechanical properties of PLA-based composites reinforced with buckwheat husks (BH) particles. work was carried out in two stages. Firstly, blend prepared addition polybutylene adipate terephthalate (PBAT) and thermoplastic starch (TPS), manufactured by injection molding technique, then selected materials were BH filler, samples using fused deposition modeling method (FDM). All subjected to assessment material properties. Thermal thermomechanical evaluated differential scanning calorimetry analysis (DSC) dynamic thermal (DMTA). Mechanical characteristic static tensile flexural measurements Charpy impact resistance tests. supplemented electron microscopy (SEM). It found that PBAT TPS greatly improves strength elongation, especially reactive compatibilizer. As expected, TPS, PBAT, reduced stiffness during DMTA testing. presence particles polymer matrix observed improve crystallization behavior PLA. optimal content filler composite be 10%, which allowed preserve good
