| Outline of Final Research Achievements |
Mechanical properties of the wood samples with various treatment which were swollen by organic liquid or mixture of water and organic liquid were examined, to explore the factors contribute to the increase of deformability and the mechanism of the deformation of wood. Mechanical properties of wood were changed due to the affinity between the wood constituents and the liquid. In particular, the creep deformation was significantly increased in the sample swollen by mixture of water and acetone, and/or the sample with the hemicellulose removal treatment.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、木材構成成分の改質や除去、また膨潤液体の種類や混合比を変化させることで、木材の力学的性質を自在に制御できることを明らかにした。これらの結果は、低エネルギーでこれまで以上に木材を変形できる可能性を示すものであり、従来の概念にとらわれない木材変形加工技術の創成に寄与できるものである。
