        摘要：A bamboo（Sinocalamus affinis） fiber composite with high specific strength and stiffness can be used for load-bearing wind turbine blades.The composite is made from 3～4 year-old bamboo culms that have been reconstituted and hot-pressed.Specimens,ranging in density from 1.08 to 1.20 g/cm3,were tested for tension,compression and fatigue properties and compared with traditional glass fiber composites.The results provide blade designers with positive preliminary technical parameters.

        摘要：Making new isolation wall materials from liquefied bamboo resin will improve bamboo utilization efficiency.Based on bamboo liquefaction and resin preparation characteristics,the authors conducted further research to understand the foaming process.Effects of a foaming agent,filler addition（calcium carbonate）,and curing agent（phosphate and p-toluene sulfonic acid） on the foaming process are discussed.Under optimized conditions,the foaming material had about 0.14 g/cm3 density and 454.5 kPa average compression strength.

        摘要：In order to reduce the cost of testing for volatile organic compound（VOC） emissions from wood-based panels,the authors designed and developed a small 15 L environmental chamber.They used a portable VOC gas monitor and gas chromatography-mass spectrometer to measure emission components and concentrations from medium density fiberboard samples.The results showed that aromatics,alkanes and olefins were the main VOC emissions.Compared with a large 1 m3 environmental chamber,the total VOC and alkane concentration levels using the small environmental chamber is slightly higher.

        摘要：The authors improved oak sliced veneer durability and surface color quality by modifying it through acetylation and then dyed the oak sliced veneer with 6 different dispersant dyes.The results indicated that dye uptake increased when increasing temperature and duration.The acetylated oak sample’s stain color was similar to that of dyed polyester fabric.

        摘要：Two formulae of furfuryl alcohol solutions with water and ethanol as the main solvents were prepared for Chinese fir（Cunninghamia lanceolata） furfurylation.The results showed that the formula with ethanol as the main solvent increased the overall sample weight by 34% and the treated samples have better anti swelling efficiency（ASE） and mechanical properties than the samples treated with the other formula using water as the main solvent.

        摘要：Fast-growing poplar and pine（Pinus sylvestris） samples were acetylated and their performances evaluated.Results showed that acetylation improved wood thermoplasticity and dimensional stability,and had no effect on wood painting film adhesion.However,the wood bonding strength was decreased.The authors believe that acetylated wood could be compressed to increase its density and hardness to meet furniture manufacturer’s requirements.

        摘要：Acoustic emission signals that were produced while drying small thin wood samples were collected and analyzed in this study.The results showed that there were mainly two different signals.One was generated during free water evaporation and the other was related to wood deformation due to the fast drying process.The authors expected that acoustic emission could be used to monitor the drying condition of samples to improve drying quality and efficiency.

        摘要：In this study,three test methods from different standards,including Chinese National Standard GB/T,Construction Industry Standard JG/T,and ISO Standard,were used to evaluate shear strength parallel to grain of 4-year Moso bamboo(Phyllostachys pubescens) samples.Shear strength related to specimen shape and loading speed was also evaluated.The results showed that: 1) there were significant differences among three test methods and specimen shapes;2) loading speed had considerable influence on shear strengths.It was found that the test configuration specified in the Construction Industry Standard was more suitable for testing shear strength,and the loading speed was suggested from 0.8 to 1.5 mm/min.

        摘要：Poplar(Populus tomentosa) and spruce(Picea asperata) samples were pretreated by soaking them in a glycerin solution before further heat treatment.Density increasing rate,moisture content,moisture adsorption antiswelling efficiency(ASE),and water absorption ASE of the treated wood samples were measured.The results showed that after glycerin pretreatment the sample’s density increasing rate increased,their equilibrium moisture content first decreased but then increased,and both moisture adsorption and water absorption ASEs also increased.
