“…Pine has the highest density as compared to avocado and mahogany (Karlinasari et al, 2010). The second causes were gluing and pressing during production process (Zhang et al, 2018;Cahyono et al, 2020). The adhesive addition might add the com-ply's weight, while the compression had the potential to change the density when changing the material properties, such as the occurrence of densification.…”

This research was conducted to investigate the linear expansion and resistance properties of a composite board (com-ply). This board was made of medium-density fiberboard (MDF) laminated using avocado (Persea americana), mahogany (Swietenia mahogani), and pine (Pinus merkusii) veneers. These three types of veneers were laminated on both surfaces of the MDF using adhesives, namely, epoxy and isocyanate. Glue (250 g･m −2 ) was spread on the surface, followed by cold press for 3 h with an applied pressure of 15 kg･cm −2 . The research result revealed that com-ply exhibited an increased dimensional stability compared with MDF, indicated by reduction in water absorption, thickness swelling, and linear expansion. The com-ply made of the pine veneer and isocyanate adhesive exhibited high density, water absorption, thickness swelling, and screw withdrawal load. The com-ply that exhibited the strongest resistance to drywood termite attacks was the one made of the mahogany veneer and isocyanate adhesive. Moreover, the com-ply that exhibited the biggest weight loss (3.6 %) was made of the pine veneer and epoxy adhesive. The results of this research may facilitate in manufacturing com-ply using the selected veneer and adhesive without the application of hot press.

“…However, with the severe shortage of high-quality timber resources in the world, although the fast-growing forest timber (e.g., poplar and pine) as a substitute is rich in resources, it has the bottleneck problem of low strength [ 11 , 12 ] and unstable size [ 13 , 14 ], which restricts its extensive and efficient use in the field of building structures. Although some lightweight structural timbers such as oriented strand board (OSB) [ 15 , 16 , 17 , 18 ], laminated veneer lumber (LVL) [ 19 , 20 , 21 , 22 ] and cross-laminated timber (CLT) [ 23 , 24 , 25 , 26 ] have been developed through structural unit reorganization and can be used as building materials, these raw materials are mostly limited to pine resources, and poplar resources with relatively lower strength and dimensional stability are not yet available for direct use as structural building materials through unit reorganization.…”

Wood is a viable alternative to traditional steel, cement, and concrete as a structural material for building applications, utilizing renewable resources and addressing the challenges of high energy consumption and environmental pollution in the construction industry. However, the vast supply of fast-growing poplar wood has bottlenecks in terms of low strength and dimensional stability, making it difficult to use as a structural material. An environmentally friendly acrylic resin system was designed and cured in this study to fill the poplar cell cavities, resulting in a new type of poplar laminated veneer lumber with improved mechanical strength and dimensional stability. The optimized acrylic resin system had a solid content of 25% and a curing agent content of 10% of the resin solid content. The cured filled poplar veneer gained 81.36% of its weight and had a density of 0.69 g/cm3. The static flexural strength and modulus of elasticity of the further prepared laminated veneer lumber were 123.12 MPa and 12,944.76 MPa, respectively, exceeding the highest flexural strength required for wood structural timber for construction (modulus of elasticity 12,500 MPa and static flexural strength 35 MPa). Its tensile strength, impact toughness, hardness, attrition value, water absorption, water absorption thickness expansion, and water absorption width expansion were 58.81%, 19.50%, 419.18%, 76.83%, 44.38%, 13.90%, and 37.60% higher than untreated laminated veneer lumber, demonstrating improved mechanical strength and dimensional stability, significantly. This method provides a novel approach to encouraging the use of low-value-added poplar wood in high-value-added structural building material applications.
