According to the CRP, a cladding is a building product if its purpose it to rest permanently in a building or a part of it and if its properties moderate the building performance. A WPC cladding undoubtedly meets this criterion laid down in Article 2.1. Furthermore, the CPR defines seven basic prerequisites to

Therefore, The behavior of the wood component of the WPC to weathering using pyrolysis-gas chromatography- contributions of plastic matrix to the WPC properties during weathering and help explain the interfacial.

Wood plastic composites (WPCs) are generally used in outdoor applications, and hence their performance and durability are affected by the ambient climate conditions. It has been shown in the many studies that composites subjected to accelerated and natural weathering show loss of mechanical and physical properties.

ABSTRACT. The popularity and demand for wood plastic composites (WPC) has focused research on fiber properties An extensive body of research has been conducted on the effect that WF size has on WPC properties (Liew et al. 2000, Stark .. Effect of wood species on property and weathering performance of wood.

Solid wood has been traditionally used for decking and siding in the. United States and other countries. However, a shift to the use of wood plastic composites (WPC) for these products is occurring due to environmental and performance issues with solid wood. With this shift, a growing concern is the long-term 

tent of the weathered WPC surface. From this study, the use of holocellulose fibers improved the weather ing performance (color) of WPCs. Introduction. Fading color and properties change of wood-plastic composites (WPC) during weathering is becoming a great concern both to the manufacturers and consum-. Fabiyi:.

Thus, to explore the weathering mechanism of WPC, improve its durability and provide some data and guide for WPC production, the natural weathering performance of bamboo powder/polypropylene (PP) foamed composites was researched. The composites containing 33% bamboo flour, 1% modified AC 

However, FRPs offer much better structural performance with similar aesthetic appeal Note that "WPC" is also used as an abbreviation for Wood Polymer Composites, which are made by impregnating .. With this basic concept at the heart of this product, claims of weathering properties and durability are
