AbstractEffects of impregnation concentration，impregnation time and impregnation temperature on static bending strength and elastic modulus of poplar reconstituted wood were studied.it was showed impregnation concentrationand impregnation time have litle influence on the static bending strength，and elastic modulus was increasing firstly and then decreasing by experimental results.static bending strength was increasing firstly and then decreasing with impregnation temperature，but impregnation temperature has little influence on the elastic modulus.

重组木的设想起源于1973年[1-3]，是80年代由澳大利亚首创的一种新型人造实体木材[4]，它是将速生小径材、枝丫材及制材边角料等廉价质地材料经碾搓设备加工成横向不断裂，纵向松散而又交错相连的网状木束，再经干燥、铺装、施胶和热压而制成的[5]。（剩余2408字）
