초록
Nondestructive evaluation (NDE) technique method using a resonance frequency by free vibration mode was carried out for heat treatment wood produced under different conditions. The effect of heat treatment on the bending strength and NDE technique using the resonance frequency by free vibration mode of wood for Korean paulownia, Pinus densiflora, Lidiodendron tulipifera and Betula costata were measured. The heat treatment temperature has been investigated at 175℃ and 200℃, respectively.
