细叶红锥(Castanopsis concina auct. non(Champ.)A. DC.)是我国阔叶用材树种,木材呈红褐色,材质坚实,不易蛀蚀,可作工业用材及家具。 本实验测试了细叶红锥木材物理力学性质,并对木材密度和各种强度进行了回归分析。 一、材料与方法 在福建省南靖县南坑区采集样木9株。 9株样木共制得符合要求的物理试件161个,力学强度试件906个,共进行各项力学试验1200次、物理性质测定1479次。 二、试验结果 1.木材物理力学性质的等级 细叶红锥木材物理力学性质的试验均值见表1。 细叶红锥木材基本密度中(偏重),材性类别中(偏高)者居多,径、弦向干缩差异属中,为1.63。
Castanopsis concina auct. Non (Champ.) A. DC.) Is a broad-leaved timber species in our country. The wood is reddish-brown in color and solid in texture. It is not easy to decay and can be used as industrial material and furniture. In this experiment, the physical and mechanical properties of the red cone wood were tested, and the regression analysis was conducted on the wood density and various intensities. I. Materials and Methods Nine samples of wood were collected in Nankeng District, Nanjing County, Fujian Province. A total of 161 physical specimens were obtained and 906 mechanical strength specimens were obtained. A total of 1200 mechanical tests were carried out, and physical properties were determined 1479 times. Second, the test results 1. The physical and mechanical properties of wood grades Fine red cone wood physical and mechanical properties of the experimental average in Table 1. Slender cone red wood basic density (partial weight), the material category (high) were the majority, diameter, chord shrinkage difference is, 1.63.
