Enhancement of product durability and usability for resource-efficient society

Technology that minimizes the amount of materials used in manufacturing, while maintaining product function, both reduces cost and optimizes resource allocation by such effects as minimizing transportation and transportation costs.

However, the complexity of interface and phenomenon correlation between different materials in a composite material prevents the progress of scientific understanding of basic processes involved in fatigue, deterioration, damage and breakage. This is a barrier to making the most of the properties, such as high strength and light weight, inherent to the composite materials.

This Prioritized Theme elucidates the principle of complex phenomena of fatigue and / deterioration for composite materials that are expected to expand in the global market, and the mechanism leading to damage and breakage. We aim to establish technology to accurately evaluate the remaining life of products, promote continuous use/reuse and minimum resource utilization by highly optimized design, and achieve material design for longer life and highly functional products.
