the manufacture of wood-plastic composites (wpc) utilizing recycled or virgin thermoplastics and lignocellulosic flour from wood or agricultural plants has gained significant attention over the past couple of decades . this new class of materials utilizes organic fillers like wood flour instead of mica, talk, .
wood flour (wf), a chemical modification of wf is an appropriate solution. this study analyzes the influence of different chemical modifications of wf on the mechanical properties of wood-plastic composites (wpcs). wpc test samples were .
wpc manufac- turing is in the form of dry particles with a powdery consistency, often called wood flour. in general, the wood waste 'raw material' is in the form of sawdust and/or planer shavings. there are two steps to produce wood flours: size reduction and size classification (screening).

bonding performances of five different adhesives to polyvinyl chloride (pvc)/wood flour composites (briefly referred to pvc-based wood-plastic composites (wpc) in this paper) were tested in this paper, in order to determine which adhesive was suitable to bond pvc-based wpc. the results showed that .
wood flour with different wood particle size were used. the mechanical properties in tension (tensile modulus and tensile strength) were determined. it was found out that these properties for both composites substantially depend on the type of wood flour. keywords: wood-polymer composite (wpc), wood flour, .
wood flour and pvc. mechanical properties. (flexural modulus and flexural strength) were determined. it was found out that mechanical properties of composite substantially depend on the type of wood flour and filling ratio. keywords: wood-plastic composite (wpc), mechanical .
wpc) belong to a group of natural fiber-reinforced compounds in which wood fibers (or wood flour) are used as reinforcing fillers in amounts generally ranging from. 50 to 80 %. a number of other natural fibers can be used for comparable applications, for example, hemp, flax, sisal, and coconut .
wood flour (founding, in the process, winchester, va.-based trex company, the first wpc board manufacturer, in 1996), durability and low maintenance have been the key selling points for .
wood flour improve the mechanical properties of thermoplastics, on the other hand it increases the burning speed of the materials. to modify the flammability of wood-plastic composites(wpc), various fire retardants, such as ammonium polysphosphate (app), melamine polyphosphate (mpp) and aluminum .
wood flour and thermoplastic(s) in addition to wood fiber and plastic, wpcs can also contain other ligno-cellulosic and/or inorganic filler materials. wpcs are a subset of a larger category of materials called natural fiber plastic composites (nfpcs) .
