The effect of microwave irradiation on wood bending was investigated in this study. The specimens irradiated with microwave were bent around a form by using pedestal-steel and clamps. The specimens, korea red pine (Pinus densiflora), for this test were water-soaked for 78 hours. Saturated specimens were boiled in water for an hour. The size of specimens was 350mm(L) by 20mm(R) by 10mm(T). These specimens were heated by microwave of 2,450MHz. The most suitable time for microwave irradiation seems to range from 60 to 90 seconds. Wood moisture content decreased remarkably with the increase of irradiation time. When a softened wood piece is bent, its convex side was stretched while the concave side was compressed. It can be compressed considerably, but stretched very little. Therefore the failure will be governed by the tensile breaking strain and occur mainly on the convex face. So we obtained results from three different bending process methods as follows : 1) When bending with a pedestal-steel, convex face had not tensile breakings, but concave face had compression fails. 2) When bending with a clamp, bending time increased more than pedestal-steel and occurred tensile breaking. 3) Bending with a pedestal-steel and a clamp was found to be the most excellent operation method in this study.
