摘要：

The hot-press temperature curves were researched and effects of hot-pressing temperature,thickness of veneer and the numbers of layer on mechanical properties of laminated veneer lumber(LVL)were analyzed with emphasis in the paper.Results showed that there was positive relationship between hot-pressing temperature and modulus of elastic(MOE);the modulus of rupture(MOR)of LVL was best when manufactured at 160 ℃.When the thickness of veneers was 3.25 mm the LVL usually destroyed due to veneer tearing;while when the thickness of veneers was 1.70 mm it easily splited in adhesive layer;the mechanical properties of LVL were best when the thickness of veneers was 1.70 mm;the 3 multinomial degrees of fitting the numbers of layers with MOE and MOR of Eucalyptus LVL matched very well,the R2 value were 0.951 6 and 0.981 2,respectively.
