Introduction To contribute to the reduction of the production of CO2 and improve the efficiency of automobiles, functional light weight composites are needed. Although many researchers have attempted to develop such materials, there is limitation on the existing technology. Therefore, not only engineers and scientists, but designers and even companies are looking to the natural world to find inspiration for new technology and idea. The scope of this project is also to develop a multi-functional materials with ideas and method from nature, so called bio-inspired materials, and produce eco-technology in bio-inspired light weight nano-composite with three dimensional structures based on self-assembly and guided self-assembly, which are resulted from low temperature and low consumption energy process. Bio-inspired materials and applications Fig.1 Schematic images of the favbriaction process and applications for the bio-inspired materials Natural system provides the best ideas and method; for instance, layered structure of organic-inorganic composite from Nacre, multi-scale hierarchical nano-composites from natural bone structures with excellent physical and mechanical properties, multi-functional properties from bio-system of integument, and low friction and high wear resistance system from shark skin. Lightweight transparent materials The technologies of nano-crystals formation based on a preferred orientation of three dimensional in amorphous structures, nano size low melting powders into glass fiber structures, functional coating on glass substrates are required for lightweight transparent materails.
