Outline of Final Research Achievements

In this project, I have conducted the optimal design of novel composite materials endowed with mechanical flexibility and high-stiffness, from both viewpoints of plant-mimetic science and nano-structure physics. The composite material was assumed to be composed of a flexible host medium and reinforcing fibers embedded in the medium, being typified by "bamboo", a fascinating tropical plant native to East and Southeast Asia. The results shed light on novel plant-mimetic design of structurally optimized composite with high-strength and lightweight properties. I also have considered the geometry-properties relations in sp2-based nanocarbons (carbon nanocoils, carbon nanotubes, etc), which is possibly caused by the combination of soft intermolecular bonds and strong covalent bonds in constitute carbon atoms. I found that a unique elasto-plastic deformation mode leads to quantum mechanical responses and thus holds promise for developing bio-inspired quantum devices based on sp2 nanocarbons.
