Outline of Final Research Achievements

Resin-impregnated compressed laminated veneer lumber (CLVL) is an old material invented in 1950s, and now it is widely used for electrical insulation, interior materials, tableware and so on. However, its dimensional stability is not enough to be used for the material of woodwind instruments. In this study, we have clarified appropriate choice of raw material (wood and resin) and the effectiveness of previous chemical modification for the dimensional stability of the CLVL. These results allow industrial fabrication of woodwind material from abundant forest resources.

Academic Significance and Societal Importance of the Research Achievements

多くの木管楽器の管体に使われているアフリカ産のグラナディラ材は絶滅危惧種であり、このまま使い続ければ、いずれ木管楽器を作れなくなる。本研究により、資源量が豊富で持続可能な国産木材を原料に、グラナディラに匹敵する性能を持った木質材料を作ることができるようになった。これは、希少な枯渇危惧種に頼らない持続可能な楽器生産につながるだけでなく、国産材の高付加価値化、ひいては国内林業の活性化にもつながる。
