Abstract

Manufacturing wood plastic composites from polyvinyl chloride (PVC) construction waste is one of the options for its continuously increasing scrap utilization. The aim of this study is to estimate the mechanical properties and durability of composites manufactured from recycled and commercially available PVC grades. The mechanical properties of PVC were reduced significantly after wood flour loading, showing weak compatibility between the matrix and the wood fibers. The composites from both PVC sources had weak durability, declining by up to 64% in tensile strength. The composite samples from recycled PVC displayed, however, better resistance to weathering compared to the composites from neat PVC. Chemical analysis of the composite surfaces by infrared spectroscopy and morphology study with a scan electron microscope before and after weathering confirmed the mechanical test results.
