        摘要：Water resistance and mechanical properties of crushed bamboo-mat composites,made from bamboo（Dendrocalamus farinosus and Phyllostachys heterocycla） mats with different node locations were studied.The results showed that the composite samples with nodes assembled in the middle portion had better water resistance and horizontal shear strength,while composite samples without nodes showed higher properties in modulus of rupture,tensile strength and compression strength.It is suggested that nodes should not be overlapped for making crushed bamboo-mat composites.

        摘要：Foaming specimens made from liquefied-bamboo resin were exposed to soil,heat,and light conditions,respectively,to evaluate their durability.The material mass loss and compressive strength before and after those conditions were tested.Results showed that the foaming material was easily degraded through soil exposure.The heat treated specimens had higher compression strength.There were some losses of weight and compressive strength after the light exposure.It was proposed that after a surface treatment,this foaming material could be used as exterior wall thermal insulation material for exterior wall building.

        摘要：Bamboo plywood was produced under different hot pressing parameters and mat moisture contents,and their properties were evaluated.The results showed that the hot pressing process,with cooling at the end of the pressing cycle,had significant influence on board surface flatness.Mat moisture content also had great effect on board thickness swelling,bending stiffness,boiled internal bonding strength,and panel flatness.The results showed that the optimal mat moisture content was around 15%.

        摘要：Thickness swelling（TS） due to water absorption is an important quality index of wood-based panel products.According to Chinese National Standard GB/T 17657-1999,TS is tested by immersing samples in（20±2）℃ water after being equilibrated at（20±2） ℃ and（65±5）% RH.The author conducted an experiment to investigate the effects of soaking time,water temperature,and the temperature and humidity of conditioning treatments on TS performance of particleboard（PB） and medium density fiberboard（MDF） samples.It was found that TS values of both PB and MDF samples increased with increasing water temperature,soaking time,and conditioning temperature and humidity.

        摘要：A brush sander is commonly used for sanding furniture components with complicated forms and shapes.In order to optimize the sanding process,roughness of red oak,cherry wood and Pinus sylvestris were evaluated after sanding with a brush sander using different belts lengths and contact depths.The results showed that belt length and contact depth had a great effect on the surface roughness.In general,a 100 mm long brush sander and a 1520 mm contact depth produced the best surface quality.
