Durability of Wood-Plastic Composites. (PDF Download Available)non-living agents (sunlight, moisture, temperature), but. often deterioration results from a combination of factors. Nowhere is this more evident than with WPCs, owing to. the marriage of dissimilar materials. Biological Agents of Damage. A variety of biological agents can attack wood and. plastic, either as a food source (primarily the wood) or as. shelter (both wood and plastic). For practical purposes, the. agents most commonly associated with WPC applications. include fungi, insects ...

OPPORTUNITIES FOR WOOD PLASTIC COMPOSITE PRODUCTS ...Richardson Hall, Corvallis, oregon, 97331, USA;. *Corresponding author: derek.thompson@oregonstate.edu. INTRODUCTION. wood plastic composite (WPC) products have gained significant market share over the past decade, especially in the residential market. The relatively high strength and stiffness-to-density ratio, and relatively low cost make WPCs a multi-purpose material that is extensively used in non-structural applications such as door skins, windows and door frames, ...

Wood-Plastic CompositesPerformance and Environmental ...22 Mar 2016 ... This chapter reviews and discusses the performance and environmental impacts of wood-plastic composites (WPCs) used in a variety of applications ranging from construction and automotive sectors to consumer goods. Performance is considered in terms of fitness for use, manufacturing methods, material components of WPCs, and user perceptions of the material. Recent research related to matrix components and their relation to mechanical properties are covered ...

Micromechanics of the internal bond in wood plastic composites ...Abstract. In this study, an integrated approach combining experimental measurements and numerical modeling was used for characterization of load transfer in the wood/matrix interface in wood plastic composites (WPCs). The experimental methodology was based on optical measurement of surface displacements and strains in model WPC specimens subjected to tensile loads. The model specimens consisted of thin HDPE films with single embedded wood particles. The optical ...

Field and Laboratory Decay Evaluations of wood-plastic Compositesdecay of woodplastic composite (WPC) materials subject to laboratory testing and exterior field exposure is limited and controversial. Data comparing laboratory test results with field performance for these composites are also lacking. (Ibach et al. 2007, Manning and Ascherl 2007, Shirp et al. 2008). WPCs are used for many applications, and a large proportion (about two-thirds) is used for outdoor applica- tions, e.g., decking, railing, fencing, and exterior covering applications, such as ...
