文县杨木材物理力学性质试验分析

Experimental Research on the Timber Physic Mechanics Character of Wenxian Poplar

在木材物理力学性质试验的基础上,研究了文县杨木材的9种常规物理力学性质,并对其材性指标进行了评价。结果表明,文县杨木材生长速度快,密度很小,顺纹抗压,抗弯及抗剪强度均低,抗弯弹性模量和冲击韧性中等。对比分析可知其木材物理力学性质与杨属类其它种木材相近,并指出其木材利用的主要方向。

Based on the timber experiment of Wenxian Poplar, the paper researched its 9 kinds of common physic mechanics characters and evaluated its timber character index. The result shows that：its timber growth rate is greater; the intensities of pressure resistant, crook resistant and cut resistant are all lower, the elasticity modulus of crook resistant and shock toughness are moderate. The contrast analysis shows that, the timber physic mechanics character is similar with the other species of Populus. The main orientation of timber utilization is pointed out.
