polyethylene sawdust composites

Characterization of chemically modified sawdust ... - CiteSeerXAbstract. Chemically treated sawdust-reinforced recycled polyethylene composites were fabricated by the injection molding method, and the effect of fiber treatment on the physicomecha- nical properties of the composites were examined. Upon treatment with sodium hydro- xide and benzoyl chloride, the hydrophilic nature of sawdust was significantly reduced. The physical properties of the composites such as water absorption, thickness swelling, and biodegradation behavior ...

Rheological behavior and mechanical properties of sawdust ...18 Feb 2009 ... We have characterized the melt rheological behavior and the solid tensile properties of sawdust/polyethylene composites prepared in an internal mixer. Various concentrations (from 0 to 60 wt %) and three particle sizes have been tested, in presence of a coupling agent (maleic anhydride grafted polyethylene). In the molten state, for each particle size, a mastercurve of the complex viscosity as function of frequency can be plotted, using a shift factor depending on ...

Flat-pressed wood plastic composites from sawdust ... - SpringerPlus23 Nov 2013 ... This study deals with the fabrication of composite matrix from saw dust (SD) and recycled polyethylene terephthalate (PET) at different ratio (w/w) by flat-pressed method. The wood plastic composites (WPCs) were made with a thickness of 6 mm after mixing the saw dust and PET in a rotary type blender followed by flat press process. Physical i.e., density, moisture content (MC), water absorption (WA) and thickness swelling (TS), and mechanical properties i.e., ...

Mechanical properties and water absorption of low-density ...4 Jan 2018 ... Full-text (PDF) | The mechanical properties and water absorption of low-density polyethylene/sawdust composites were investigated. The relationship between the filler content and the composite properties was also studied. Different degrees of esterification of the sawdust with maleic anhydride wer...

Study of Wood-Plastic Composites with Reused High Density ...Solid plastic waste from polymers such as high density polyethylene is creating new challenges for an industry that is seeking greater waste utilization to ensure products that are efficient ecologically and environmentally friendly [5,6]. The cost and quality of these composites depends on the waste type incorporated, on the material and the processing route used [4]. The sawdust waste produced by the sawdust industry is about 5% per tree log, which makes this an important ...

Mechanical properties of composites from sawdust and recycled ...ABSTRACT: Mechanical properties of wood plastic com- posites (WPCs) manufactured from sawdust and virgin and/or recycled plastics, namely high density polyethylene. (HDPE) and polypropylene (PP), were studied. sawdust was prepared from beech industrial sawdust by screening to the desired particle size and was mixed with different virgin or recycled plastics at 50% by weight fiber loading. The mixed materials were then compression molded into panels. Flexural and tensile ...

Mechanical Properties of Chemically Treated Sawdust-Reinforced ...20 Aug 2011 ... In the present work, cetyltrimethylammonium bromide (CTAB)-treated sawdust-reinforced recycled polyethylene (RPE) composites were prepared by injection molding method. The mechanical properties of RPE composites reinforced with CTAB-treated sawdust were evaluated and the results were compared with those of untreated ones. The tensile strength (TS) values of the CTAB-treated composites were found to be much higher than those of the untreated ones.

Compressive mechanical properties of sawdust/high density ...16 Feb 2016 ... This article is concerned with the static and dynamic mechanical properties of high-density polyethylene (HDPE) reinforced with sawdust (SD) at a strain rate of up to 10<sup>3</sup> s<sup>1</sup>. In this study, the static and dynamic properties of HDPE/SD composites with different filler loadings of 5, 10, 15, 20, and 30 wt% SD were deliberated at different levels of strain rates (0.001, 0.01, 0.1, 650, 900, and 1100 s<sup>1</sup>) using a conventional universal testing machine and the split Hopkinson&nbsp;...

Compressive Mechanical Properties of Sawdust/High Density ...This article is concerned with the static and dynamic mechanical properties of high-density polyethylene. (HDPE) reinforced with sawdust (SD) at a strain rate of up to 103 s21. In this study, the static and dynamic properties of HDPE/SD composites with different filler loadings of 5, 10, 15, 20, and 30 wt% SD were deliber- ated at different levels of strain rates (0.001, 0.01, 0.1,. 650, 900, and 1100 s21) using a conventional universal testing machine and the split Hopkinson pressure bar.
