Summary

Design of self-diagnosis mechanism in/with composite materials is proposed. Composite materials are not only developed for improvement of mechanical performances but also achievement of damage monitoring capability. This proposal opens the door to new era of materials design. Strengthening and diagnosis of damage are achleved simultaneously in/with composite materials consisting of two different materials A and B, where material A is of high elastic modulus and electrically conductive while material B is of high tenacity and electrically insulating. A typical example of the combination of materials A and B is carbon fibers for A and glass fibers for B. Addition of carbon fibers to glass fiber reinforced plastic increases elastic modulus and gives damage monitoring capability by measuring change in electric resistance while addition of glass fibers to carbon fiber reinforced plastic gives a way to avoid sudden fracture. The concept of materials design, integration of structural performance and damage monitoring with simple structures as simple as possible, is proposed as “Ken-materials” by the author. The concept is extended to self-diagnosis of ceramic base composite.
