On the basis of the nanocomposite technology, we have proposed the new materials design concept "multi-functional materials" (Intermaterials), in which multi-functions such as mechanical and electric properties are realized in a composite. In order to develop such a novel material, close international collaboration researches is strongly required. Therefore, we have proposed Japan-United States-Korea international research project. Three famous research groups, the institute of Scienlific and Industrial Research, Osaka University (Japan), MIT of United States of America, and Korea Institute of Science and Technology, are joined in this project.The purpose of this project are to clarify the mechanisms of mechanical and functional properties improvements and to develop various kinds of multi-functional materials (Intermaterials) including of ceramic-, metal- and polymer-based composites by applying this nanocomposite technology and molecular-level compositing technology. The final target … More of this project is to propose the nano/cluster composite concept with better multi-functional properties, based on the nanocomposite technology.The main results obtained from this project is as follows :1) Development of new fabrication processing to obtain high-performance ceramic-based nanocomposites. Novel processing of powder preparation and sintering including in-situ compositing processes have been developed. This resulted in successive fabrication of high-performance nanocomposites in ceramic/ceramic and ceramic/metal nanocomposite systems.2) Design, development of multi-functional ceramic composites. We have succeeded to obtain new nanocomposites with multi-performance, in which both mechanical and functional properties have been realized in one composite materials. Here, adding new functions to structural ceramics as well as superior improvement of mechanical properties of functional ceramics (such as ferroelectric and ion conducting materials) have been succeeded in ceramitc/metal nanocomposite systems and functional-ceramic-based nanoconiposites.3) Development of novel organic-inorganic composites constructed by nano- and molecular-level structural control. By attempting nanocomposite technology and molecular design concept to polymer materials, high-performance fiber-reinforced plastics and molecular-composites have been developed.These materials indicated the superior mechanical and thermal properties even at cryogenic temperatures.All these results shows the possibility of realizing multi-functional nano- and molecular-composites (Intermaterials).
