Investigations on ageing of wood-plastic composites for outdoor

Oct 15, 2016 EN 15534 Part 1 contains information about which material properties need to be elaborated for WPC compounds and which synthesized test methods should be applied. EN 15534 in Natural ageing is investigated by the exposure of samples for one year to weathering conditions equal to South France.

Natural weathering properties of acetylated bamboo plastic

Jun 27, 2012 Therefore, the purpose of this study is to investigate the natural weathering properties of bamboo plastic composites (BPCs) showed that the retention ratios of mechanical properties of acetylated BPCs, especially those containing fibers with a high WG In fact, wood plastic composite (WPC) is promoted.

ultraviolet light protection and weathering properties of wood - Doria

Dec 1, 2014 The main aim of this thesis is to study the effect of pigments on the weathering properties of wood-polypropylene composites (WPC). The studied properties are color change, water absorption, thickness swelling and Charpy impact strength. The impact of weathering and UV exposure on WPCs was studied

The influence of accelerated weathering on the mechanical and

Mar 4, 2015 properties of wood-plastic composites (WPC). The goal is also to evaluate the importance of wood flour fraction size on the mechanical properties of WPC and their influence on the accelerated weathering results. Wood flour reinforced composites with three different fractions of wood flour made from birch

Wood-Plastic Composites: Weathering Quality Issues : Plastics

Who knew? Not the wood-plastic composite (WPC) manufacturers because the materials were too new on the market. Outdoor applications for wood and natural-fiber composites grew in 10 to 15 years from zero to over 2 billion lb/yr with little or no statistical data or test methodology to study the effects of weather and aging.

Surface Characterization of Weathered Wood-Plastic - StellarNet Inc

Abstract. The effects of weathering on the surface properties of wood-plastic composites (WPC) were examined. High-density polyethylene (HDPE) based WPCs made from modified wood flour (untreated, extractives free, and holocellulose (delignified) fibers) were subjected to accelerated (xenon-arc) weathering.

Effect of weathering on physical and mechanical properties of hybrid

They concluded that water absorption and thickness swelling of the composites were increased after accelerated weathering (Adhikary et al. 2009). On the other hand, weathering causes WPCs lose their mechanical properties. Moisture penetration into the WPC degrades the wood-polymer interface, which in turn causes

Considerations in Weathering Wood-Plastic Composites - CiteSeerX

Pigments, ultraviolet absorbers, and hindered amine light stablilizers have been used with some success in mitigating changes that occur during WPC weathering. Pigments were shown to mitigate the increase in lightness and significantly increase the flexural property retention of WPCs after accelerated weathering [2].

Weathering Characteristics of Wood Plastic Composites Reinforced

Jul 23, 2016 Weathering of WPC resulted in a surface lightening and a decrease in wood index (wood/HDPE) and flexural strength. WPCs that were reinforced with delignified wood flour showed higher ΔL* and ΔE* values, together with lower MOE and MOR retention ratios upon weathering when compared to those
