Mechanical Behavior of Wood Plastic Composites: Effect of Interfacial Compatibilizers

In this study, wood plastic composites (WPC) material were fabricated with wood flour and polyvinyl chloride (PVC). To improve the interfacial compatibility between the wood flour and the PVC, silane method (SM) and tianate method(TM) were used to treat the wood flour, maleic anhydride copolymerized PVC with dicumyl peroxide. The effects of wood flour content, surface treatment on the mechanical properties of WPC materials were investigated. Fracture surfaces of tests specimens were analysis by SEM. Test results indicate that WPC material with wood flour treated by SM or TM together with PVC copolymerized showed good mechanical properties.
