In order to make a new movement of the composite material design, the purpose of the present study is applying the solid-air composites derived from the load dispersion structure of living bones to investigate the static load dispersion function shown by the mechanical behavior of those constitutive elements. Internal hydrostatic pressures were controlled by making a hole in cell walls of the honeycomb core. Static indentation tests were carried out to examine the load dispersion effect. In-plane cell's deformations and stress distributions at the bottom surface of the specimens were measured optically. Experimental results illustrated that the distribution of the internal hydrostatic pressures greatly influenced on the deformation condition of the solid part. Consequently, it is considered that controlling the internal hydrostatic pressures is an effective design parameter of the load dispersion function.
