        摘要：A crushed bamboo-mat composite has a high potential in exterior structural applications.The mechanical properties and dimensional stability of the bamboo composites,after an accelerated six wet-dry cycle and water boil tests,were studied.The results showed that the average modulus of rupture,modulus of elasticity,and shear strength of moso-bamboo composites,after the accelerated test,were no less than 120 MPa,13 000 MPa,15 MPa,respectively.The thickness swelling of the composite was no more than 5%.The mechanical performance of Neosinocalamus af finis bamboo composite,after the accelerated test,was even better.

        摘要：The authors examined the effects of three different sawing procedures on the deformation of two hardwood logs（Schima superba and European beech） to improve lumber quality and utilization efficiency.They found that through-and-through sawing resulted in the best results for medium diameter logs.They also found the saw-dry-rip method improved dimensional stability for flatsawn boards ripped from the width direction and quartersawn boards ripped from the thickness direction.

        摘要：Surface densification and post-heat treatment were used to improve the dimensional stability of Pinus yunnanensis samples.The process involved hot pressing for 10 minutes under 150 ℃ and then heat treatment for 2 hours under 180 ℃ or 220 ℃.The results showed that hot-pressing to densify the surfaces was an effective way to improve surface hardness and bending property of samples.Heat treatment for these surface densified sample could improve their dimensional stability considerably,such as,equilibrium moisture content,water absorption,thickness swelling,but decrease their modulus of rupture slightly.

        摘要：As the irregular shape of blocks,it is difficult to get the best positioning with traditional positioning methods.The authors developed a new precise scanning method which is cheap and could easily transform blocks profiles into digitization.By projecting laser beams on rotating blocks,reflected images of the blocks were obtained.Then processed by software,the actual displacement from the blocks surface to the axis of rotation centers was calculated.Finally,the 3D contour of the blocks can be easily constructed.

        摘要：The effects of wood flour size and coupling agents on the mass flow during the wood plastic composite extrusion process were studied.The result was that as the wood flour size decreased,the flow resistance increased and the wood plastic composite color become darker.Considering the manufacturing cost and the composite performance,the authors determined wood flour from 45～60 mesh should be used with a lead stabilizer and aluminate coupling agent.
