Outline of Final Research Achievements

Our objective is to develop a plastic forming process using superplastic-like behavior of wood which was firstly found by AIST. Meanwhile the mechanism of such large deformability tried to be revealed by various methods. We could partially understand the large deformability leading to superplasticity of solid wood to investigate the effects of changes in nano-scale pores and adsorption sites in amorphous region as well as interfacial properties such as cell-cell interaction and intercellular layer on the deformation behaviors of solid woods impregnated with various resins. Applying to plastic forming technology of metals based on the obtained results related to deformation behaviors of resin-treated solid wood, arbitrary-deformed 3D products with a better size stability, strength and thermal stability could be fabricated using their improved deformability, which have been hardly prepared by conventional shaping techniques of wood.
