Over the past decade, there has been a growing interest in the development of construction and industrial products composed of wood fiber combined with thermoplastic resins. This mainly due to wood plastic composites (WPC) are renewable, less-abrasive to processing equipment, environmental friendly, low maintenance and similar as wood feature. The use of wood waste as filler make WPC promoted as environmental friendly products.
WPC and WPC process was patented in Italy around 1920s. In this process, polypropylene and wood flour were extruded to manufacture automotive interior parts. There was not much of an interest on this process until one American company implementing this Italian extrusion technology to produce automotive interior substrates (Clemons, 2002). This has followed by other companies to produce various shapes of automotive parts by extruding polypropylene and wood flour mixtures. Applications for these composites include a variety of building products, consumer, industrial and automotive. Recently, WPCs have found application areas other than automotive industry such as siding, fencing, window frames and decking. Especially after their use in decking applications, manufacturing of WPCs has seen phenomenal growth in the United States. It is well known that decking has a tremendous market in the USA with approximately 18.5 million m3 in 2000 (Winandy, 2004).
As the use of wood-plastic composite (WPC) materials extends to include more structural applications, there is an increasing need to determine design values appropriate for designing structural WPC elements. However, there are two important topics shall be clearly
