“…The processing and use of poplar veneers are strongly influenced by wood defects such as soft texture and low density (Zhou et al 2017;Guélou et al 2022). In addition, most poplar wood is hygroscopic and highly sensitive to water (Dong et al 2016).…”

Fast-growing poplar (Populus tomentosa Carr) can produce wood veneers, but their poor quality restricts their application in construction and building. Modification of wood has the potential to improve its properties. In this study, poplar veneers were impregnated with calcium carbonate (CaCO3) to reinforce their performance. The results showed that CaCO3 was uniformly distributed in cell lumens in impregnated veneers. After impregnation, the maximum weight gain rate was up to 41.4%, and water uptake decreased from 6.82% to 0.94%. The hardness increased from 7.6 to 10.0 MPa, and the extent of wear fell from 0.91% to 0.05%. The ignition time was prolonged, and the heat release rate and total heat release were low. Experimental results demonstrated that CaCO3 improved the physical-mechanical properties and flame retardancy of poplar veneers.

This research paper studies the influence that the number of plies has on the identification of the mechanical properties of poplar Laminated Veneer Lumber (LVL) from tensile tests, such as its stiffness. LVL poplar specimens were prepared with different ply configurations and subjected to uniaxial tensile tests. Longitudinal and tangential rigidity were characterised in this research paper. The results show that the ply configuration influences the mechanical properties. The influence of the glued faces, the presence of lathe checks, and the glue line are also studied as well as the compression ratio of veneer during the manufacturing of the LVL. All these results provide valuable information for the design and optimization of laminated wood structures. An analytical modelling strategy is proposed to account for the effect of ply numbers, ply orientations, the compression ratio of veneers and the glue used on the stiffness of poplar laminate both in longitudinal and transverse directions.
