| Research Abstract |
This research purpose is to develop the new composites by the biomimetic design. This project consists of the basic research 1 to establish concrete design principles by solving the load dispersion mechanism of the bone, the basic research 2 to develop optimum design techniques of the new composites, and the practical research to develop the molding and processing techniques of them. The basic study 1 had been achieved by applicants in the previous results. Therefore, the basic research 2 and the practical research were achieved within the term on this grant-in-aid. For putting "the solid-air composites" proposed by applicants as a result of the basic research 1 to practical use, the numerical analyses and the experimental measurements were applied to investigate its load dispersion properties under dynamic loadings.
Consequently, the following results were obtained.
(1).The solid-air composites were made by sealing air into honeycomb core with two silicon films, those dynamic load dispersion properties were experimentally evaluated by applying dynamic indentation testing machine, multi-channel dynamic strain transducer and digital high-speed video camera.
(2).The numerical database for the structural optimum design of the solid-fluid composites on dynamic load dispersion properties was constructed, where the dynamic stress transmission at the solid-fluid interface was numerically modeled by applying finite element analysis.
(3).The above results were published in four domestic journals and two international ones.
