Abstract

The effect of heat treatment on the dynamic viscoelasticity of the woods of Picea sitchensis and Paulownia coreana which have been for musical instruments was investigated. The treatment was made in a temperature range of 60-180$^{\circ}C$ for periods of 3 hours to 24 hours. The results obtained are summarized as follows: Moisture absorption decreased with increasing temperature. Dynamic Young's modulus decreased with increasing temperature and hours. Dynamic viscoelasticity decreased with increasing moisture content, but internal friction increased with increasing amount of moisture content.
