Basic Study on Damage Restraint of Coating Film

2nd Report, Improvement of Damage Restraint Effect

Abstract

Recently, coating materials are widely used in the several fields. However, it is being taken up as a serious problem that the large-scale destruction of the structure will be occurred at the time when the damage of the coating film generates. In the previous report, the basic study on the efficiency of actively restoring the bending damage of the film by adopting the concept called smart material or smart structure was proposed, and the effectiveness was shown. However, the problems of improvement on the reactivity of the actuator and application of the flexible processor function were pointed out. In this paper, the smart structure body is reported that is constituted by the information from the added strain gauge as the sensor function and the applied neural network as the processor function. As the result, it was showed that the problems of the previous report could be improved.
