Degradation of Polylactic Acid Polymer and Biocomposites Exposed to Controlled Climatic Ageing: Mechanical and Thermal Properties and Structure

This paper deals with the study of degradation polylactic acid (PLA) material structures and biocomposite systems a PLA matrix containing ground natural particulate waste fillers, buckwheat husks egg shells. Waste fillers were used without difficult cleaning operations to describe effect raw on PLA. Biocomposites materials are increasingly coming forefront in car interiors packaging products. The prepared exposed controlled climatic ageing simulating long-term solar radiation cyclic outdoor conditions. was evaluated via thermal (differential scanning calorimetry) mechanical properties (tensile flexural tests, Charpy impact toughness). In addition evaluating using standardized influence visually assessed SEM images (electron microscopy) surfaces fracture test specimens.
