wood-plastic composites wpcs have emerged as potential eco-friendly and cost-effective alternatives to inorganic fiber polymeric composites. in the last decade, several major industries, such as the construction and building industries, have shown considerable interest in the progress of high-wear-resistance wpc materials omrani et al. 2016 .
polymers used in wood plastic composites are mostly polyolefins such as polyethylene particularly hdpe and pp. pvc is also used as well, particularly in windows, doors and house shingles. styrenic polymers such as ps and abs find occasional applications in wood composites. composites contain both wood fibers and wood flour.
this bcc research report gives a comprehensive study of all cellulosic-plastic combinations as well as plastics that are direct competitors in the drive to replace lumber in building and construction markets. these segments include wood-plastic composites, plastic lumber, cellulosic plastics and natural fiber composites.
in addition to various wood species, various other natural fibers have been included into fiber-plastic composites. examples include bast fibers flax, hemp, jute, kenaf, ra-any species can be incorporated into wpcs. non-wood fibers can also be used.
than long wood fibers, which tend to agglomerate and cause dispersion problems during mixing. however, because of their higher aspect ratio, long fibers provide greater reinforcing effects in wood plastic composites wpcs than particles. the fiber can be difficult to disperse but the dispersion
polymer composites is the engineering and scientific journal serving the fields of reinforced plastics and in this article it was used to replace part of a wood fiber wf filler to reinforce highdensity polyethylene hdpe . this study indicated that paper mill sludge could be used in wood plastic composites, which would reduce
composite lumber is a material that is a mixture of wood fiber, plastic, and some type of binding agent. these ingredients are put together to form a material that is denser, stronger, and heavier than wood alone, a wood-plastic composite
from all fiber reinforced composites produced in europe 15% = 400,000 t of total are reinforced with natural fibers like wood or bast fibers like hemp and kenaf. only a small share of 15,000 tons of these so called bio-based composites was injection-molded, with an average fiber share of 42% in 2012.
more recent references on wood plastic composites from thermoplastic polymers include oksman et al. and klyosov . also of interest is the production of eco-composites utilizing bio-derived polymer matrices . this review will focus on wood plastic composites manufactured from thermoplastic polymers and wood flour or wood fibers.
outreach activities in- cluded the organization and presenta- tion of two international conferences on wood fiber-plastic composites, pre- sentations at many conferences, publi- cation of several papers, and several spin-off cooperative studies with indus- try. one major study with industry dem- onstrated the commercial feasibility of making
the construction and municipal waste plastic-wood fiber based biocomposites exhibited undesirable properties compared with virgin plastic ldpe-based wood-plastic composites . multicomponent systems using such mixed plastic wastes mostly pp and pe deliver inferior performance due to incompatibility.
wood-plastic composite. wood plastic composites wpcs are composites manufactured from predominantly typically synthetic thermoplastic resins and wood flour filler, though thermoset resins and naturally derived resin systems may also be used. and this capacity rose to 260,000 in 2012 spear and eder, 2015; schwarzkopf and burnard
