Solid-fluid biomimetic composites by considering load dispersion mechanismof cancellous bone structure (Consideration of honeycomb structure)

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 import ant role in the load transmission. So, the solid-fluid composite model equa l to the cancellous bone was made by using honeycomb structure. Static inde ntation 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 great ly influenced on the in-plane deformation condition of the solid phase. Con sequently, as for the solid-fluid composite models, the compressive load di spersion by the solid-fluid phase interaction was expected.
