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 ...

Provided it has been properly processed and implemented in structural applications, including protecting against biological attacks and accounting for moisture induced movements, wood is able to withstand considerable duration of loading thanks to its good resistance to fatigue and sophisticated multi-scale composite structure. For that reason, it is still present as the structural element of v...

Thermal modification is a well-known process to change the dimensional stability, hygroscopicity, and biological resistance of wood due to chemical modifications of wood cell components. In this study, we reviewed several characteristics of heat-modified solid wood and wood-based panels under various temperatures, durations and pressure. Thermal compressing treatment could affect drying speed, ...

A novel wood-based composite has been developed for use in structural applications. The process was designed to utilize rapidly-grown, low density, wood species. Plantation grown radiata pine is particularly well suited to this process. This is a laminated composite, where the lamina may be comprised of various materials, some of which have been treated with the viscoelastic thermal compression...

A novel biomass composite inspired from wood porous structure was manufactured by impregnating vinyl monomer into wood cellular structure under vacuum conditions, and initiating the monomer for in situ polymerization through a thermal treatment. The vacuum condition was studied, and the mechanical properties of the composite were also tested. SEM observation shows that polymer generated in the ...

injection molding is one of the most common processes which are used for manufacturing different plastic parts. this method includes 3 continuous steps: filling of the mold, cooling and driving the part out. a wide range of plastic and non-plastic materials can be used as raw material in this process. one of the most important advantages of this way of production is that it is very economic. in...

In wood-based composite panels, low-molar ratio (LMR) urea-formaldehyde (UF) resins usually result in reduced formaldehyde emission (FE) at the expense of poor adhesion. However, FE and adhesion medium-density fiberboard (MDF) bonded with LMR UF were both improved this study. The modified transition metal ion-modified bentonite (TMI-BNT) nanoclay simultaneously MDF panels. 5% TMI-BNT resulted a...

Recently, a processing technique resembling plastic-type forming has been developed for solid wood. To improve the recyclability of the formed products, thermoplastics were used as a binder. In this study, a hydrophobic monomer of methylmethacrylate (MMA) was used as a thermoplastic binder and was impregnated into wood, then polymerised by heat to form polymethylmethacrylate (PMMA). The effects...
