        摘要：Bamboo-based fiber composite specimens,developed for wind turbines,were heat treated at 80 ℃ for 8 hours and 50 ℃ for 24 hours.Their surface appearance and some mechanical performances were then evaluated.The results showed that some small and discontinuous cracks were observed after the heat treatment.However,the heat treatment had no obvious influence on the mechanical properties.The treated composite had slightly improved tension,compression,horizontal shear strength properties.

        摘要：Decorative wood-based panels,overlayed with metal foil,have become more popular in China due to their appearance and low cost.The authors sought to improve the panel’s durability by modifying regular phenol-formaldehyde resin by mixing it with thermoplastic resins and coupling agents to improve the bonding performance between aluminum foil and MDF panels.The results showed that modified phenol-formaldehyde resin improved surface bonding strength and reduced water soakage.Although the modified resin reduced the mechanical properties,they still met the requirement of industry standard LY/T 1983-2011.

        摘要：Knots are one of the main natural defects that affect wood utilization.The authors sought to have a better understanding how knots affected glue laminated board performance by testing and analyzing the shear modulus of 100 mm×88 mm×48 mm Pinus sylvestris samples with different knot types and size.The results showed that knots present in the gluing surface influenced the bonding.Generally,knot size had more effect than the knot type on shear strength.The conclusion is that knots with diameter more than 25 mm significantly reduced the shear strength and should be removed.

        摘要：In order to improve rubber wood heat treatment technology,the authors investigated the amount of organic acid released and its effect on rubber wood performance during high temperature heat treatment.The results indicated that increasing the temperature and the heat treatment duration increased the amount of organic acid released which improved the color appearance and decay resistance of treated wood.However,it possibly had a negative impact on bending strength.

        摘要：Workshop air pollution is one of the most visible environmental problems in China.Inhalable particulates,in particular,have recently drawn more attention due to the pronounced influence on air quality and human health.In this study,the concentration and distribution of total suspended particulates（TSP）were investigated during the straw crushing process.The result showed that the concentration of inhalable particulates,with diameter less than 10 μm（PM10）,was much higher than the requirement specified by the national standards,and the proportion of particulates with diameter less than 2.5 μm（PM2.5） reached 0.01%.

        摘要：The authors measured moisture contents in solid wood flooring in different apartments in multistory building in Nanjing,Jiangsu province.The results indicated that the average moisture content of flooring located near windows and balconies facing toward the south were lower than those located near windows in north facing bedrooms,except for the first floor where there was no obvious difference among moisture contents of the same solid wood flooring species.Generally,the moisture content decreased when the floor location increased.This paper provides useful information to produce solid wood flooring with reasonable moisture content and flooring installation.

        摘要：Edge-glued panels made from Tsuga heteophylla,Hevea brasiliensis and Carya spp.were tested for bonding,shearing,and bending performance.The results showed: 1) the edge-glued samples,after the immersion delamination test,met the type Ⅰ requirements specified in the National Standard GB/T 21140-2007,but the finger-jointed samples failed to meet the type Ⅱ requirements entirely.2) the average shearing strength of edge-glued samples was about 5.0% less than the average solid wood shearing strength parallel to grain.3) the average bending strength of the finger-jointed samples was about 26.2%77.9% of the solid wood bending strength.

        摘要：The authors pretreated Poplar（Populus euramevicana） with a surface densification process to improve utilization.The process involved hot pressing for 2.5 hours and heat treatment for 3 hours.The results showed that the samples increased surface hardness,modulus of elasticity,and tangential dimensional stability following surface densification.However,modulus of rupture decreased slightly due to hemicellulose decomposition whereas paint film hardness of poplar flooring increased but coating adhesion and coating wear resistance were unchanged.

        摘要：The authors used wild plant stalk（miscanthus floridulus） to make oriented stalk board with fire resistant performance to add value to the abundant resource.The stalks were reduced by chopping them into elements with a target dimension of 4 mm wide,4 mm thick,and 105 mm long.Before being dried,they were treated with diammonium hydrogen phosphate（DAP） in 4%,6% and 8% concentrations,respectively.The test results showed the samples made with the DAP treated stalks had considerably improved fire resistant performance.
