Analysis of Anatomical Character and Physical-mechanical Performance of 6 Wood Species

To further study of the bending processing performance of six wood species, such as Zelkova schneideriana, Betula alnoides, Hevea brasiliensis, Fraxinus chinensis, natural Tectona grands and artificial Tectona grands. The proportion of vessel tissues, fiber length, density, whrinkage and bulging, maximum load, MOR, MOE and maximum bending deformation were studied. The results indicated that study the proportion of vessel tissues and fiber length of Z. schneideriana were significantly different from those of other 5 wood species. The order of the proportion of vessel tissues size is as follows: Z. schneideriana> F. chinensis > B. alnoides > artificial T. grands > natural T. grands > H. brasiliensis. The order of fiber length size is as follows: Z. schneideriana> F. chinensis > H. brasiliensis > artificial T. grands > natural T. grands > B. alnoides. The density of B. alnoides was significantly different from that the other 5 species, and the density difference among Z. schneideriana, H. brasiliensis, F. chinensis, natural T. grands and artificial T. grands is not significantly, and they are all moderate density; The whrinkage and bulging of radial direction smaller than the tangential direction of 6 wood species in 2 condition. While the chord ratio of the Z. schneideriana is the largest, and the natural T. grands is the smallest; The maximum load, MOR, MOE of B. alnoides are the largest among the 6 wood species. The F. chinensis has the best bending performance, and the natural T. grands has the worst bending performance. The order of bending deformation size is as follows: F. chinensis > B. alnoides> artificial T. grands > Z. schneideriana> H. brasiliensis > natural T. grands.
