properties of wood-plastic composites wpcs reinforced with extracted and delignified wood flou r abstract: the water sorption and mechanical properties of wood-plastic composites wpcs made of extracted and delignified wood flour wf has been investigated. wf was prepared by extraction with the solvent systems
the water sorption and mechanical properties of wood-plastic composites wpcs made of extracted and delignified wood flour wf has been investigated. wf was prepared by extraction with the solvent systems toluene/ethanol te , acetone/water aw , and hot water hw , and its delignification was conducted by means of sodium chlorite/acetic acid aa solution.
thus, although it is inferior to wood in several mechanical properties, for some structural or semi-structural functions, plastic lumber and thermoplastic composites are alternatives to wood lumber. in addition, the use of high-aspect-ratio fillers and specific fibre orientations are effective ways to produce thermoplastic composites with mechanical properties that are closer or similar to those of wood.
the wood plastic composites were manufactured using 60% pine wood flour and 40% pp on a davisstandard woodtruder . dynamic mechanical thermal properties, polymer damping peaks tan , storage modulus e , and loss modulus e were measured using a dynamic mechanical thermal analyzer.
pyrolysis-gas chromatography/mass spectrometry py-gc/ms was employed to investigate the primary pyrolysis product distribution of the pyrolysis of wood-plastic composites wpcs and the mutual effects of poplar wood pw and high-density polyethylene hdpe .
mechanical and physical properties of the panels manufactured from combination of plastic and wood material and fibre with addition of various types of chemicals are shown in table 2. average moe value of the samples containing 60% and 80% wood fibre without having any chemicals was found 2,109 mpa figure 6 .
this study investigated weathering performance of an hdpe wood plastic composite reinforced with extracted or delignified wood flour wf . the wood flour was pre-extracted with three different solvents, toluene/ethanol te , acetone/water aw , and hot water hw , or sodium chlorite/acetic acid. the spectral properties of the composites before and after artificial weathering under accelerated
