进口实木地板木材物理力学性质的研究

本文测量研究了三种进口实木地板用材——纤皮玉蕊（Couratari sp．）、圭巴卫矛（Goupia glabra）和香脂木豆（Myroxylon balsamum）的物理性质和力学性能。测定和分析结果表明：这三种木材密度大，差异干缩小、尺寸稳定性好。抗弯弹性模量中或高，批弯强度为高，冲击韧性为中或低，顺纹抗压强度高，综合强度高，为优良的实木地板用材。

This paper measures and researches the wood physical and mechanical properties of Couratari sp. ; Goupia glabra and Myroxylon balsamum which are three imported solid wood floors. The results show that the gravities of these three materials are high, the contrasts of shrinkage are low with good dimensional stabilities. Their bending modulus of elasticity are middle or high class; the bending strengths are high; the stiffness are middle or low; the compression strength parallel with grain are high, and the comprehensive intensity are high. They are all good materials for solid wood flooring.
