Abstract:
Asanuma et al. have been developing Smart Materials and related technologies, especially Smart Mechanical Material Systems which have high mechanical properties as well as smart functions useful for severe environments such as those in aerospace fields. In spite of advancement of science and technology, a large number of people have been lost due to disasters around the world. To cope with this problem, Asanuma et al. have been trying to build a platform to create novel ideas and technologies by involving people from various advanced fields such as Smart Materials and Structures. They have proposed “Disaster Mitigation and Sustainable Engineering” which is aiming at sustainability as well as disaster mitigation effectively and economically. Asanuma has been demonstrating innovative material systems and processing to realize smart/multifunctional and robust mechanical material systems to be used for above mentioned fields. The developed material systems can be classified into a couple of types. The Type I material systems can be obtained by embedding fragile functional materials in a metal matrix such as aluminum to be used even in severe environments. An innovative fabrication process invented by Asanuma has enabled successful fabrication of optical fiber/aluminum composites and piezoelectric ceramics fiber/aluminum composites. The Type II material systems can be obtained without using those fragile functional materials. An innovative designing concept to realize them has been developed, that is, a couple of competitive structural materials because of their similar and high mechanical properties are combined together to maintain high mechanical properties and also generate functional properties due to their dissimilar secondary properties. Successful examples of this type are the active laminates and the Ti fiber/Al multifunctional composites. These innovative material systems can be modified in a variety of ways such as the active laminates with healing function, morphing function, and so on. Asanuma is looking for applications of the above mentioned materials and technologies in aerospace fields especially based on Disaster Mitigation and Sustainable Engineering.
