effect of the nanosilica content in the shell of

weathering durability of woodplastic composites wpcs is a significant issue for outdoor applications. nanosilica is widely used to enhance the ultraviolet uv aging resistance of composites. in this study, the effects of nanosilica 0%, 1%, 2%, 5%, and 10% added into the shell of coextruded wpcs were investigated after 2500hour uv exposure.

effect of weathering on the properties of wood

weathering properties hinder the outdoor applicability of wood-polymer composites wpcs . there are two main elements which may affect the performance of wpcs significantly: ultraviolet radiation and moisture. both the wood and polymer components of a composite can undergo degradation while exposed to uv irradiation.

mechanical properties: wood lumber versus plastic lumber

conclusions. there is a need for studies that focus on these properties to provide more data for a comprehensive comparison. thus, although it is inferior to wood in several mechanical properties, for some structural or semi-structural functions, plastic lumber and thermoplastic composites are alternatives to wood lumber.

influence of weathering on visual and surface aspect of

moreover the chain scission attested by size exclusion chromatography sec and lixiviation on the surface induces roughness and gloss loss. otherwise biocomposites were more degraded under natural weathering. this paper gives new insights in understanding how weathering affects physico-mechanical properties of wood plastic composites wpc .

the effects of weathering on wood-thermoplastic composites

now that wood-plastic composites have become a major player in the north american decking market, many of the lessons learned in how treated-wood decking has historically been used, removed from

effect of wood species on property and weathering

the effects of wood species on mechanical, thermal and accelerated weathering behaviors of high-density polyethylene based wood plastic composites wpc were investigated. the selected wood species are poplar, douglas-fir, black locust, white oak, and ponderosa pine. hybrid poplar and douglas-fir based composite ranked highly in flexural properties.

wood-plastic composites: weathering quality issues

weathering forecast. overall moisture content of a wood-composite deck board is usually claimed to be less than 2%. however, material at the board ends and 1 to 7 mm below the board surface 'frequently exceeds 25% moisture,' gnatowski notes. that 25% moisture is an open invitation for fungi to attack wood-plastic composites.

photodegradation and photostabilization of weathered wood

weathered composites both unstabilized and stabilized as well as the effect of weathering on the color fade and the retention of mechanical properties were characterized.
