In the present study, the properties of polycaprolactone (PCL) and wood flour (WF) blends were examined by Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), Instron mechanical tester, and scanning electron microscopy (SEM). As for results, the mechanical properties of PCL were lowered obviously, due to the poor compatibility between the two phases, when it...

Wood liquefaction using an organic solvent and an acid catalyst has long been studied as a novel technique to utilize biomass as an alternative to petroleum-based products. Oxalic acid is a weaker organic acid than a mineral acid and wood liquefaction with oxalic acid as a catalyst will result in a higher amount of wood residue than that with a mineral acid. Yet the wood residue can be used as ...

Surface roughness and wettability of flat-pressed wood plastic composites (WPCs) incorporated with various fire retardants (FRs) (5, 10, or 15% by weight (wt)) at 50 wt-% content of the wood flour (WF) were investigated. The most common FRs, zinc borate (ZB), magnesium hydroxide (MH), and ammonium polyphosphate (APP), were used in the experiments. The WPC panels were made from dry-blended wood ...

Wood flour is the most common filler used in production of wood plastic composite (WPC) materials. In scientific studies on this subject, flours obtained from different trees and fillers annual plants are used. addition, some mineral-based also materials made plastic. study, a low-density polyethylene polymer form granules recycling was as matrix. Larch glass by grinding soft drink bottles were...

tobacco is planted extensively in golestan province and high volume of its stem wastes remained without using and it is burned. as a useful purpose of these wastes and to reduce the environmental problems, in this the mechanical properties of polypropylene composites reinforced with tobacco stalk flour were studied. for this purpose, the tobacco stalk flour as the reinforcement, in three levels...

This study used a high-density polyethylene (HDPE) polymer matrix, pine-wood flour (PWF) and walnut-shell (WSF) to produce wood-plastic composite (WPC) boards. The PWF WSF filler amounts were adjusted 20%, 30%, 40% by weight. Some of the mechanical properties produced boards comparatively investigated, such as flexural strength, modulus, deformation at break, tensile elongation break. Flexural ...

With its market demand expansion and increased application areas, products of wood-plastic composite (WPC) have been developing growing rapidly in many countries over the last decades. This paper attempts to investigate effect wood species that are waste from furniture industries on performance composites (WPCs). The samples were prepared by varying flour at 30wt% mixed with 70wt% HDPE (High De...
