Abstract
In this research, polylactide was hybrid-reinforced and heat-treated in order to obtaindurable structural materials with the use of eco-friendly components. Differential scanningcalorimetry (DSC) analysis, tensile tests at various temperatures, Vicat tests, impact tests, andmicroscopic observations were conducted on the annealed and non-heat-treated specimens.The theoretical and true density, as well as water absorption, were also determined. The simultaneousintroduction of chopped carbon and basalt fibers in equal mass fractions of 7.5% and 12.5% resultedin satisfactory increases in stiffness and tensile strength. The reinforcing effect was more efficientfor the heat-treated composites, especially at elevated temperatures. Heat treatment significantlyincreased the degree of crystallinity of the matrix, improving heat resistance and reducing waterabsorption. It also reduced the stress concentrations in the injection-molded specimens.
