Study of Wood Plastic Composites on Mechanical and Thermal Properties after Immersed into Water

Article Preview

Abstract:

In this study, silvergrass (SV) reinforced high density polyethylene (HDPE) composites were prepared. The effects of slivergrass fibers (SV) content on the mechanical properties, crystalline properties of wood plastic composites (WPCs) before and after water absorption were investigated. It was found that compared with the untreated WPCs after immersed into water, the tensile strength of PMDI treated composites were higher. Silvergrass can be the nucleating agent with treated by PMDI. The Xc of PMDI treated WPCs after immersed into water was also increased. However, this improved Xc has negative effect on mechanical properties.
