Wood-Polymer Composites: Review of Processes and Properties

Abstract Wood-polymer composites (WPC) are made from wood and monomers that are polymerized inside the wood. Combining wood with polymer enhances the physical properties of the wood, allowing the composite to be tailored to specific applications. This paper reviews the processes and monomers used to make WPC, physical properties of WPC, and actual and potential applications. The characteristics of traditional monomers (methyl methacrylate and styrene) and new monomers are described, as are WPC surface hardness, water repellency, dimensional stability, abrasion resistance, and fire resistance. Current and potential uses for WPC range from hardwood flooring to furniture, sports equipment, parts for musical instruments, industrial applications, and construction materials.
