Abstract: This paper deals with the methods of softening timber by RF heating and of fixing the shape of bending stock by RF drying, taking P. stenoptera and C. tricuspidate as the sample, and analyzing the main factors such as power density and wood moisture content. The rate and quality of softening timber by RF heating are tested, and the time needed for fixing the shape by RF drying and honey combing degree of bending stock are determined under the various power conditions. The tests show: 1. The time needed for softening timber by RF heating is less than about 12 times that by steam-softening. 2. The time needed for fixing the shape of bending stock by RF drying is less than from 120 to 180 times that by the traditional kiln drying, even more, a better quality can be obtained.
