- 摘要：Wood is one of the first noted and the oldest materials used in human history. Wood has been utilized as the building and home furnishing materials for thousands of years. With the intensifying of environment pollution and energy depletion, how to use wood in a high-quality and efficient way has become a bottleneck problem for the wood industry to achieve the goals of the scientific frontier and the human health. In order to increase the self-value, self-repair, self-diagnosis, and self-adaptability of natural wood, by learning from nature, we developed the intelligent wood products with bionic structures, which have proved to be an effective strategy to serve our society at a highly technical level. This review aims to highlight the significance of bionic constructed advanced functional wood products in the field of energy, environmental protection and intelligent manufacturing by discussing the basic theories, novel technologies and strategic impacts. We highlight the current literature in details including the development trends regarding the functional wood materials, and the challenges in manufacturing technologies and applications. In the conclusion, we provide suggestions for the future directions and opportunities of the wood bionic science.关键词：wood;bionics;intelligence;low carbon;Sustainable development

摘要：The drying schedule for Chinese Acacia melanoxylon lumber with 40 mm in thickness was studied to serve as a scientific basis for the practical production of wood drying. The results showed that the drying process lasted for 453 h (18.9 d) when the moisture content of wood decreased from 105.9% to 9.8%. The final average moisture content met the requirements of the 2nd in the national standard GB/T 6491—2012 "Drying quality of sawn timber", while the drying evenness, the moisture content deviation in thickness, the residual drying stress, and visible drying defects of the dried lumbers all met the requirements of the 1st grade of GB/T 6491—2012.关键词：Acacia melanoxylon;drying schedule;drying speed;drying quality- 45

摘要：The wood fiber reinforced magnesium oxide composite (WRMC) material, as a new decorative building product, has been used in the construction and decorating field due to its excellent physical and mechanical properties. The cutting force and the surface roughness of the workpiece during taper milling of WRMC were studied. The results showed that the cutting force was positively correlated with the milling depth, but negatively correlated with the taper angle and the milling speed. The surface roughness increased with the increase of the milling depth and decreased with the increase of taper angles and milling speeds. An optimized cutting parameter combination with the taper angle of 75°, the milling speed of 45 m/s, and the milling depth of 0.5 mm was proposed. Under the above conditions, the cutting force and the surface roughness were 50.24 N and 2.11 μm, respectively.关键词：wood fiber reinforced magnesium oxide composite (WRMC);tapered milling;cutting force;surface roughness- 54

摘要：In this study, the modified bamboo with a battery of weight percentage gain (WPG) was prepared by controlling the mass fraction of the furfuryl alcohol resin solution. The effect of WPG on the dimensional stability, the water absorption, the surface wettability, mechanical properties, and the thermal stability of modified bamboo were evaluated, respectively. With the increase in WPG, results indicated that the water absorption and contact angles of bamboo significantly decreased at the initial stage, then gradually slowed down the decreasing process. The anti-swelling efficiency (ASE) value increased and gradually become flat when the WPG was higher than 20%. An reduction in the modulus of rupture was observed, while the modulus of elasticity slightly increased. The residue carbon weight ratio increased and had a linear correlation with the WPGs. It was feasible to improve the comprehensive properties of modified bamboo by managing the WPGs reasonably.关键词：Moso Bamboo;furfuryl alcohol resin;modification;weight percentage gain (WPG);physical-and-mechanical properties- 49

摘要：In this project, scrimber was prepared from defibered Cupressus funebris veneer using the recombination technology. The surface properties, the water resistance and bending properties of scrimber were evaluated. The results showed that the density was the main factor affecting the surface properties and bending properties of Cupressus funebris scrimber. The surface roughness decreased, the surface contact angle and the bending strength increased as the density of scrimber increased. The hot-pressing temperature had a great effect on the water resistance. So, the water resistance of scrimber improved as the hot-pressing temperature increased. The bending strength of Cupressus funebris scrimber reached 160 MPa, which was 2.55 times of the standard value in LY/T 1984—2011"Reconstitued wood flooring". Therefore, the manufacturing of scrimber can be an effective way for the high-value-added utilization of Cupressus funebris resources.关键词：Cupressus funebris;scrimber;hot-pressing temperature;density;surface properties;water resistance;bending properties- 58

摘要：In-situ molding composites made of wood/bamboo splinter (fruit tree wood, poplar, elm, and bamboo) and Ganoderma lucidum mycelium were studied. The results showed that the fruit tree wood splinter was suitable for the mycelium growth. The thickness swelling rate of water absorption of different type composites at 2 h and 24 h were 3.71%~9.56% and 8.82%~13.29%. The compressive strength of fruit tree wood splinter/mycelium in-situ molding composite (GG composite) was the highest value at 10% deformation. The final mass residual rate of GG composite was 35.56% after the thermogravimetric test, the maximum loss rate was at minimum(0.57%), GG composite showed good thermostability. The thermal conductivity of the GG composite was less than 0.093 W/(m·K), which thermal insulation performance was similar to that of the commonly used thermal insulation materials in the building industry. GG composite display good compressive strength, thermostability, and thermal insulation performance.关键词：wood/bamboo splinter;Ganoderma lucidum;mycelium;in-situ molding composites;compressive strength;thickness swelling rate of water absorption;thermal insulation properties- 30
