Mechanical Properties of Polylactide Filled with Micronized Chalcedonite

One of the methods of changing the mechanical properties of polymeric materials is by the creation of composites with various substances whose task is to strengthen and fill them. Thanks to the use of fillers, we can obtain new materials with interesting mechanical and chemical properties. Among the materials obtained, some of the features are often improved, while the others deteriorate. In this study, an attempt was made to obtain a polymer composite based on a PLA filled with macaroni chalcedonite in the amount of 5%, 10%, 15%, 20% and 30% by weight. The properties of the mechanically obtained mixtures were assessed. The tests show that the number of substances in the composite had a significant effect on changing the properties of the obtained material.
