소원택,So, Won-Tek 한국목재공학회 1983 목재공학 Vol.11 No.2
Hornbeam trees(Carpinus laxiflora BL.) are growing in Korea and have good characteristics such as relatively high density, fine texture, split-resistance, and white colour. However, they have seldom been used as manufacturing materials This study was carried out to evaluate the possibility of using hornbeam wood as bent-wood furniture materials. Softening methods were steaming and micro-wave heating. The specimens of $15{\times}15{\times}350mm$ were used green or air-dried, and were steamed at $100^{\circ}C$ for 20min, or microwave heated for 60 seconds. The bending processing conditions are showed in Table 3. The minimum solid-bending radii of air-dried wood were 40mm for steaming and 200mm for micro-wave heating, respectively. And that of green wood were 40mm for micro-wave heating. In conclusion, both of the steamed wood and micro-wave heated green wood showed very good solid bending processing properties, but micro-wave heated air-dried wood were not sufficient for bent-wood furniture.

고주파 평면가열에 의한 중밀도섬유판(MDF)의 핑거접합
소원택,So, Won-Tek 한국가구학회 2006 한국가구학회지 Vol.17 No.2
This experiment was carried out to investigate the high-frequency gluing characteristics of poly vinyl acetate emulsion adhesive(PVAc) on MDF edge-glued boards. The edge-glued boards were glued lengthwise with butt, scarf, or finger joint. The wastes of MDF boards were reused as board materials. The obtained results are summarized as follows; the bending strength of edge-glued MDF increased slightly with the HF heating time, but the economically desirable heating time was 6 minutes. The bending and tensile strength of edge-glued MDF were high with scarf, finger and butt joint, in order. The strength of finger jointed MDF showed 80% of scarf jointed MDF. The effects of location of finger joints on the bending strength of edge-glued MDF were larger than those of the numbers of finger joints. The bending strength of edge-glued MDF with one joint on the middle position showed 40% decrease in comparison with non-jointed MDF.

핑거접합방식에 의한 삼나무의 고주파가열 집성판 제조에 관한 연구 (1) - 삼나무 판재의 초산비닐수지 접착특성 -

This experiment was carried out to investigate the gluing characteristics of poly vinyl acetate emulsion adhesive(PVAc) on the Cryptomeria japonica laminated boards. This sample trees are major planting species and have been planted in southern district for a long time. The optimum gluing conditions for laminated board were summarized as follows; the amount of spreading glue, assembly time, clamping pressure, and clamping time for PVAc resin were $200g/m^2$, 10min., $5kg/cm^2$, and 6hrs., respectively, and the relative formulae between extension ratio(x) and block shear strength(y) was $y=-9.6x+85.2(R^2=0.95)$.

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.
