Raising the bar on WPC durability : CompositesWorldDecay of WPCs depends not only on formulation but geography, says Douglas gardner, professor of wood science and technology at the AEWC Advanced Structures and composites Center, University of Maine (Orono, Maine). For example, WPC decks in Florida showed evidence of red fungal fruiting bodies on surfaces within a few years after installation, implying the wood in the materials was still susceptible to bio-degradation. Similar observations have been reported in other ...

Study of Wood-Plastic Composites with Reused High Density ...In recent years, concerns about environmental preservation have motivated industries to adapt towards more environmentally friendly materials, resorting for this to recycled and waste materials. This has been the center for a growing number of research studies to enable less and less virgin materials waste [1], [2]. The use of recycled thermoplastics has been considered for the production of wood and plastic composites in recent years [3]. New materials have been developed with a ...

Chair: Marie-Pierre G. Laborie. wood plastic composites (WPCs) are gaining increasing popularity in exterior applications. However, the weatherability of WPCs drives the need for developing surface finishes that would offer both protection and aestheticism. Developing a suitable coating system for WPCs requires a thorough understanding of the surface properties,.
