garden fence panels,environmentally friendly flower box ,decking cost calculator uk
Man has a long history of using lignocellulosic materials for producing composites.garden fence panels Its beginning can be traced back to the ancient times when the Egyptians added straw to mud to make bricks, which proved to be very strong and durable. Today, bio-based composites are becoming attractive in both commercial and non-commercial appli- cations . Wood plastic composites (WPCs) are widely used throughout the world; the most common type of such panels is produced by mixing wood flour and plastics. These composites are transformed by extrusion processes to obtain structural building applications including, pro- files, sheathings, decking, roof tiles, and window trims, with improved thermal and creep performance compared with unfilled plastics . In general, the stability of any building system consisting of interconnected components is directly related to the performance of the fastening ele- ments. Common wire nails and screws are widely used for making joints on WPCs particularly in decking, outdoor furniture, etc.environmentally friendly flower box because of their good performance and low cost . Therefore, knowledge of the withdrawal strength of nails and screws for WPCs will provide useful infor- mation about the stability and durability of the materials in the building system . Although numerous studies have been carried out to evaluate the withdrawal strength of different types of fasteners (such as dowel, nail, and screw).Accelerated deforestation and forest degradation, in addition to a growing demand for wood-based products, have raised an important issue regarding the sustained supply of raw materials. Consequently, there is need for alternative resources to substitute wood raw materials. Therefore, researchers, both in industry and academia, are looking for new sources of lignocellulosic materials. Among the possible alternatives, the develop- ment of composites using agricultural residues, non-wood plant fibers, and fast-growing species could play a major role in providing the balance between supply and demand for the manufacturing of wood-based composites such as WPC .,decking cost calculator ukAgricultural residues are excellent alternative waste materials to substitute wood because they are plen- tiful, widespread, and easily available. Aside from their abundance and renewability, utilization of agricultural residues has advantages for economy, environment, and technology .
