| 摘 要： | 分别采用气干、常规干燥及高温干燥方法,对毛白杨木材进行干燥,并检测分析3种干燥方法对毛白杨木材的抗弯弹性模量(MOE)、抗弯强度(MOR)、冲击韧性及硬度等力学性质的影响.结果表明,3种干燥方法对MOE及MOR无显著影响,但高温干燥时木材的冲击韧性及表面硬度有较大的影响.

| Abstract: | Plantation grown populus tomentosa lumber was dried using three different methods: air drying,conventional drying,and high temperature drying.The mechanical properties of the dried lumber were evaluated and the effects of the different drying methods on the lumber performance were examined and compared.The mechanical properties measured in this study included modulus of elasticity(MOE),modulus of Rupture(MOR),toughness,and hardness,The results showed that both of the average MOE and MOR values of the three ... |
