The poplar (Populus deltoides) wood samples were pressure-impregnated with different concentrations of nanoparticle-fortified resin formulations to evaluate the effects on physico-mechanical properties and decay resistance. The impregnation of higher concentrations of nano ZnO fortified PVAc (3% ZnO fortified...
Poplar wood was modified by a combination of thermo-mechanical densification (TMD) and heat treatment (HT) process at five temperatures ranging from 170 to 210°C. A new two-step conditioning method (CM) is suggested, in the course of which the modified wood is submitted to 50°C/99% RH...
The hardness of wood varies with the direction of thewood grain. Testing on the surface of a plank, perpendicular to the grain, is said to be of “side hardness”. Testing the cut surface of a stump is called a test of “end hardness”. Side hardness may be further divided into “rad...
Density profile relation to hardness of VTC wood composites was evaluated using X-ray densitometry and modified Brinell hardness method using different applied forces. Moreover, surface elasticity was evaluated. Prior to lamination, the low-density hybrid poplar ( Populus deltoides 脳 Populus trichocarpa...
The influence of silane coupling agent and poplar particles on the wettability, surface roughness, and hardness of UF-bonded wheat straw(Triticum aestivum L.)/poplar wood particleboard[J]. Seyedeh Masoumeh Hafezi,Kazem Doosthoseini.Journal of Forestry Research. 2014(03)The influence of silane ...
Wood speciesThe objective of this study was to evaluate the effect of heat treatment on surface roughness and hardness of four wood species, namely black alder (Alnus glutinosa L.), red oak (Quercus falcata Michx.), Southern pine (Pinus taeda L.) and yellow poplar (Liriodendron tulipifera)....
The results showed that density has a positive effect on SH and BH of panels. It was also observed that wood species (beech or poplar) and size of strands (normal or fine size) also effect on SH. Both species showed a specific behavior regarding the lapse of stress and strain during ...
We used silane coupling agents to improve the bonding ability between wheat straw particles and UF resin, and investigated surface properties (wettability and surface roughness) and hardness of particleboard made from UF-bonded wheat straw (Triticum aestivum L.) combined with poplar wood as affected...
Optically transparent wood is a type of composite material, combining wood as a renewable resource with the optical and mechanical properties of synthetic polymers. During this study, the effect of monochromatic UV-C (λ—250 nm) radiation on transparent
