Solid-Fluid Biomimetric Composites by Considering Load Dispersion Mechanism of Cancellous Bone Structure : Consideration of Honeycomb Structure

Abstract

The purpose of this research is to apply biomimetic designed composites to artificial structures. Looking at the bio-joint mechanism, the solid-fluid composite structure of the cancellous bone is likely to play a great important role in the load transmission. So, the solid-fluid composite model equal to the cancellous bone was made by using honeycomb structure. Static indentation testing was carried out, and in-plane deformation conditions of the solid-fluid composite specimens were measured quantitatively. Experimental results illustrated that the hydrostatic pressure of the fluid phase greatly influenced on the in-plane deformation condition of the solid phase. Consequently, as for the solid-fluid composite models, the compressive load dispersion by the solid-fluid phase interaction was expected.
