The influence of the treatment parameters on the physical and mechanical properties were investigated. The wood samples were densified under three compression ratios (0%, 30%, and 50%), and thermally treated at three temperatures (180 degrees C, 200 degrees C, and 220 degrees C), at three thermal treatment durations (3 h, 4 h, and 5 h). The density, modulus of elasticity, modulus of rupture, radial hardness, and thickness swelling were measured. The results showed that the densities of the samples increased by 36.6% to 49.7%. As the compression rate increased, the temperature, duration, modulus of elasticity, modulus of rupture, and hardness increased. However, the dimensions of the densified samples were less stable. Compared to the densified samples, the maximum thickness swelling could be reduced by 74% (from 29.7% to 7.8%) when subjected to a thermal treatment at 220 degrees C for 3 h.application/pdfenCreative Commons Attribution-NonCommercial 4.0 InternationalDensificationHeat treatmentPhysical propertiesMechanical propertiesEffects of Thermo-Hydro-Mechanical Treatments on Various Physical and Mechanical Properties of Poplar (Populus) WoodArticle - RefereedBioresourceshttps://doi.org/10.15376/biores.15.4.9596-9610154
