In this study, poplar wood and a phenol-formaldehyde (PF) resin were used to produce a large-scale scrimber product by a combined cold pressing and heat curing method. The water resistance, mechanical properties, and formaldehyde emission of the scrimber boards prepared at different core temperatures (l00[degrees]C, 110[degrees]C, 115[degrees]C, and 120[degrees]C) were investigated. The results showed that the peak core temperature had a significant effect on the scrimber performance. The thickness swelling rate and width swelling rate of the scrimber boards prepared at a core temperature of 100 [degrees]C were significantly higher than other samples. The formaldehyde emission from the surface layer of the scrimber boards prepared at a high core temperature (115[degrees]C and 120[degrees]C) was much lower than that at a core temperature of 100[degrees]C and 110[degrees]C. These results can be explained by the correlation between curing degree and temperature of the PF resin in the scrimber. With increasing core temperature, the modulus of rupture, compression strength, and horizontal shear strength of the scrimber boards first increased and then decreased, suggesting that core temperature during the heat curing process also played an important role in determining mechanical properties. The scrimber boards with the best mechanical properties were prepared at a core temperature of 115[degrees]C. The results of the study demonstrated that the optimal core temperature necessary to produce a low-cost and high-performance scrimber was 115[degrees]C., Poplar scrimber is a high-performance wood-based composite material made from poplar fluffed veneers and a low-molecular-weight phenol-formaldehyde (PF) resin, which has the characteristics of not disrupting the orientation of the [...]
