Mechanical properties of talc- and (calcium carbonate)-filled poly(vinyl chloride) hybrid composites

The main objective of this study was to investigate and compare the mechanical properties of poly(vinyl chloride) (PVC) composites filled with calcium carbonate (CaCO3), talc, and talc/CaCO3. Talc and CaCO3 with different grades were incorporated into the PVC matrix. To produce the composites, the P...
