| 内容記述 | In this paper, investigations were carried out on to a few fundamental properties of the following hardwoods : Kiruki-wood (Idesia polycarpa Maxim.), Inosugi-wood (Actiondapnne logiforia (Blume) Nakai) and Okinawaurajirogashi-wood (Quercus salicia Blume) grown in Amamiooshima, Kagoshima pref. These specimens were obtained in the stems measuring from 0.2 m to 4 m in heights above the ground, along the stem diameter, through pith from sapwood to another. In the handlings, the following physical and mechanical properties were examined. 1. Physical properties (moisture content in green condition and specific gravity in air drying condition). 2. Bending-strength test (a test carried out to ascertain the bending strength and modulus of elasticity in bending). 3. Impact-bending test (a test to ascertain the absorbed energy in impact bending). 4. Compressive-test (a test to ascertain the compressive strength parallel to grain). 5. Shearing-test (a test to ascertain the shearing-strength in the tangential and radial planes). 6. Cleavage-test (a test to ascertain the cleavage-resistance in the tangential and radial planes). The experimental results obtained about the physical and mechanical properties are summerized in Table 1 and Figs.1-7. 1. A moisture conntent in green condition ranged from 113% to 23% (average 66%) in kiruki-wood, from 126% to 29% (average 91%) in Inosugi-wood, and from 113% to 23% (average 66%) in Okinawaurajirogashi-wood. 2. A specific gravity in air condition in Kiruki-, Inosugi and Okinawaurajirogashi-wood ranged from 0.34 to 0.74 (average 0.55), from 0.51 to 0.67 (average 0.59) and from 0.60 to 0.95 (average 0.81), respectively. 3. A value of specific gravity of Kiruki-wood was equivalent to Yachidamo-, Shinanoki-, and Shioji-wood ; Inosugi-wood, to Kusu-, Kuri-, and Kuwa-wood ; Okinawaurajirogashi-wood, to Shirakashi-, and Isunoki-wood, respectively. | |||||
