processing methods for wood plastic composites

Effects of processing method and fiber size on the structure and

The aim of this study was to understand the roles of processing method and fiber size on the properties of wood–plastic composites (WPC). composites were manufactured using extrusion or injection molding (IM) and fibers of different fiber 

Wood–Plastic Composite Technology SpringerLink

4 Jun 2015 wood–plastic composites (WPCs) are a form of composite combining wood-based elements with polymers. An important constraint for polymers used in WPCs is requiring process conditions (melt temperature, pressure) that will not thermally degrade the wood filler. wood to better understand the mechanisms contributing to various degradation issues as well as methods to improve
