Compressive and flexural properties of biomimetic integrated honeycomb plates
Graphical abstract
Highlights During the fracturing of biomimetic plates, there is no abrupt compression paralysis. Ultimate failure of biomimetic plates is determined by the material strength itself. Consequently, biomimetic honeycomb plates possess good mechanical properties. Effectiveness of the biomimetic honeycomb plates manufacturing method were confirmed.
Abstract The characteristics of honeycomb plates composed of an upper and lower lamination are employed to create a novel single-sided bonded honeycomb plate (SBHP) design, and the compressive and flexural properties of these biomimetic integrated honeycomb plates are investigated. The results demonstrate that even during the fracturing of the honeycomb plates (honeycomb core), no abrupt compression paralysis occurs (which would cause the load to decrease rapidly); furthermore, our honeycomb plates exhibit superior compressive properties compared to biomimetic sandwich plates manufactured using Zhang’s needle-injection method. The interfacial bonding surface and bonding quality have no significant effect on the flexural stiffness but do affect the failure modes and flexural failure strength of the honeycomb plates. The ultimate failure of the biomimetic integrated honeycomb without a bonding layer between the panel–core layers is determined by the material strength itself; therefore, the honeycomb possesses good mechanical properties. This experimental study confirms, for the first time, the effectiveness of the biomimetic integrated honeycomb structure manufacturing method.
