Bending Processing Properties for Parts of Furniture: I . Solid Wood-Bending of Larch Wood by Boiling Treatment

This study was performed to investigate the solid wood bending properties of larch wood (Larix lep- tolepis Gord.) grown in Korea by boiling treatment. The specimens were green and their dimension was l5x l5x350mm. The optimum conditions for solid wood bending processing of larch wood are showed in Table 5 and the minimum solid-bending radius was 280mm in boiling treatment. The effect of pin knots, resin pockets, and torn grains on the concave side of bent wood on the degradation of bending processing properties were very severe and their bending failures were 90%, 95%, and 50%. respectively, when bent to a 300mm radius.
