high density wood composite

Morphology, mechanical properties, and dimensional stability of ...Four types of wood particles with various compositions including native wood flour (WF), hemicellulose-removed particle (HR), holocellulose (HC), and -cellulose (C) were prepared and compounded with high density polyethylene (HDPE) in an extruder, both with and without maleated polyethylene. Injection molding was used to make test specimens. The HR-based composites exhibited the best water resistance. The HC-based composites obtained a greater tensile modulus but a ...

Dimensional stability and mechanical behaviour of woodplastic ...This paper investigated the stability, mechanical properties, and the microstructure of woodplastic composites, which were made using either recycled or virgin high-density polyethylene (HDPE) with wood flour (

Preparation and Properties of Wood Plastic Composites Made of ...This article deals with experimental investigation of composites based on recycled high-density polyethylene (RHDPE) and poplar fibers (Populus deltoids) formed by air-forming and hot-pressing. The effects of the fiber content (55, 70, and 85 wt%) and compatibilizing agent (0, 2, and 4 wt%) concentration on the mechanical properties and water absorption were evaluated. The use of polyethylene-grafted maleic anhydride (PE-g-MA) improved the compatibility between the fiber and ...

Composites from compounding wood fibers with recycled high ...The development of composites consisting of wood fibers and recycled plastics offers not only an opportunity to utilize an abundant natural resource but also a means to alleviate the serious plastics disposal problem. In this work, aspen fibers are incorporated into recycled high density polyethylene with a co-rotating inter-meshing twin-screw extruder to study processing-property relationships. Tensile, impact, and flexural strengths are measured as functions of fiber concentration.

Weathering of High-Density Polyethylene-Wood Plastic Composites ...18 Sep 2013 ... Abstract. Due to the widespread use of wood-plastic composites (WPCs), high-density polyethylene-wood flour composites (HDPE/WF) were studied in order to determine their stability in different application conditions. UV degradation and periodic absorption/desorption of moisture cause damaging changes to material during WPCs' exterior application, so it is necessary to ensure WPCs' durability against atmospheric influences. Samples were characterized by FTIR ...

Flammability and flame-retardant mechanism of high density ...1 Jun 2016 ... Abstract. Fabrication and characterization of a novel high density polyethylene/wood fiber/modified ammonium polyphosphate (HDPE/WF/MAPP) composite have been carried out. The flammability of the composite is characterized by the limiting oxygen index (LOI), vertical burning test (UL-94), and cone calorimetry. The flame-retardant mechanism is investigated by Fourier transform-infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), and scanning electronic ...

Wood-fiber/high-density-polyethylene composites: Coupling agent ...26 Jan 2005 ... Abstract. The coupling efficiency of seven coupling agents in woodpolymer composites (WPC) was investigated in this study. The improvement on the interfacial bonding strength, flexural modulus, and other mechanical properties of the resultant wood fiber/high-density polyethylene (HDPE) composites was mainly related to the coupling agent type, function groups, molecular weight, concentration, and chain structure. As a coupling agent, maleated polyethylene ...

Wood-thermoplastic composites from wood flour and high-density ...16 Jun 2009 ... Abstract. high-density polyethylene/wood flour (HDPE/WF) composites were prepared by a twin-screw extruder. The effects of WF, silane coupling agents, polymer compatibilizers, and their content on the comprehensive properties of the WF/HDPE composites have been studied in detail, including the mechanical, thermal, and rheological properties and microstructure. The results showed that both silane coupling agents and polymer compatibilizers could improve the ...
