pdf in this work the performance of gypsum plaster and wood particle in pastes and composites was investigated. wood particles of fineness 0.42 mm and 1.20 mm were employed. natural wood
wood plastic composites with 90 days of natural weathering were too evaluated for 120 days, where was monitored co 2 generation fig. 1-b . by both composites without and with 90 days of natural weathering the coupled composites showed a greater release of co 2.
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 .
the tensile strength of uniaxially reinforced all-cellulose composite was 480 mpa at 25 c, and the dynamic storage modulus was as high as 20 gpa at 300 c. these were comparable or even higher than those of conventional glass-fiber-reinforced composites. in addition, a linear thermal expansion coefficient was about 10-7 k-1.
processing temperatures are one of the few portions of the manufacturing phase where wood-plastic composites differ significantly from conventional plastics. wood-plastic composites generally process in temperatures around 50 degrees lower than the same, unfilled material. most wood additives will begin to burn at around 400 degrees fahrenheit.
wood plastic composites made from post-used polystyrene foam and agricultural waste. 2016, 3800 metric tons of durian were produced in malaysia alone and it is estimated that 1040 1046

wood-plastic composite material is a new environmentally friendly material that is based on wood fiber e.g., wood flour, bamboo flour, and rice husk powder, etc. and plastic, and prepared by molding and extrusion. it is a composite material made from thermoplastic polymer plastic as the matrix and filled with wood fiber particles borah and kim 2016 .
weathering of wood--plastic composites wpcs leads to discoloration and cracks, which greatly limits their outdoor application. in this study, light stabilizers including uv-327, hs-944 and nano-sio2 were added to the shell of a co-extruded high-density polyethylene-based wpc to improve its anti-ultraviolet uv ageing properties and simultaneously to maintain its good mechanical properties.
the use of such polymers as the matrix in wood plastic composites wpcs is one of the growing areas of interest because of the expanding wpcs market and the cost competitiveness achieved by taking advantage of cheap, abundant and biodegradable wood fibres as structural fillers .
