In the thesis, we focus on a comprehensive review of the thermal and rheological properties of filaments made from pure polylactic acid (PLA) and copper-filled mixture of polylactic acid with polyhydroxyalkanoate (PLA/PHA). The objective of the thesis is to gain valuable insights into the processing conditions and potential applications of these materials. We aim to examine the behavior of PLA-based materials under different conditions and their suitability for applications in industries that prioritize sustainable and environmentally friendly practices, including the food, medical, automotive, electrical, and additive manufacturing industries, contributing to improved mechanical performance and wider utilization. The research includes conducting thermal analysis using the Differential Scanning Calorimetry (DSC) method to study the melting temperature, crystallization, and thermal stability of the as-received materials. For sample preparation, we will utilize the micro injection molding method. This technique allows the production of samples with standardized geometries, such as discs and rods, serving as representative samples for evaluating material properties. Subsequently, we will determine thermal properties of the micro-injection-molded samples using the DSC method to determine whether material properties have changed during the injection molding process. Additionally, we will perform rheological characterization to examine flow behavior and material processing parameters.
