湿地松木材物理力学性质研究

Study on Physical and Mechanical Properties of Pinus elliottii

研究湿地松木材的主要物理力学性质,并对各指标间的关系进行了回归分析,结果表明:(1)按我国木材材质等级划分标准,可以得出湿地松木材气干密度属轻,强度指标属低。(2)强度指标与气干密度之间表现为一元线性关系,其中抗弯强度、冲击韧性显著。(3)抗弯弹性模量与抗弯强度具有密切的线性关系。

Some wood properties of P.elliottii were tested and their relationship was analysed in this paper.The results were as follows:1.P.elliottii specific gravity belonged to light grade and intensity low grade;2.Intensity had a linear relation with specific gravity;3.The relationship between bending modulus of elasticity and bending strength was also linear.
