摘要

研究杉木、杨树和巨桉等6种人工林木材两两混合胶合的剪切强度、木破率和剪切强度效率（剪切强度与密度的比值）等性能的差异。结果表明:人工林木材混合胶合是可行的,不同组合间胶合性能差异显著;"中与中"密度组合的胶合性能较好,"低与中"密度和"中与高"密度组合的次之,"低与高"密度组合的最差。

Abstract

Bonding performances of glued-lumber specimens made from two different species were evaluated in this study.A total of six plantation grown wood species,including Chinese fir（Cunninghamia lanceolata）,Poplar（Populus×canadensis cv.’I-214’）,Eucalyptus grandis,E.grandis×E.urophylla,E.citriodor,and E.exserta were selected.The shear strength,percentage of wood failure,and shear-strength efficiency（defined as ratio of shear strength to density） were used to evaluate the bonding performance.The result showed that density was the dominate factor that determined the bonding strength.It was found that specimens made from two species with similar density had a high average bonding strength,while the specimens made from two species with a significant difference in their densities resulted in poor bonding performance.
