抄録: | The aim of this study was to evaluate the bending quality for ten kinds of main Korean wood species and to investigate the effect of the metal strap thickness on the bending quality of Korean red pine. Bitter wood (Picrasma quassioides), horn beam (Carpinus laxiflora), birch (Betula schmidtii), painted maple (Acer mono) and cork oak (Quercus variabilis) showed excellent quality. Sargent cherry (Prunus sargentii), Korean red pine (Pinus densiflora) and pitch pine (Pinus rigida) showed intermediate quality. Basswood (Tilia amurensis) and royal paulownia (Paulownia tomentosa) showed worse quality. The density of wood species was the main factor to determine the bending quality. As for the relationships between annual ring orientation and metal strap thickness, the bending quality of specimens with intermediate annual ring orientations was better than that of flat-grained specimens in the strap thickness of 1.0 mm and 0.8 mm, while the reverse result was obtained in the strap thickness of 0.6 mm and 0.4 mm. These findings suggested that it was important to determine the appropriate strap thickness in relation to wood species, thickness of specimens, form radii and annual ring orientations in specimens. |
