New Honeycomb Structure Withstands Repeated Impacts

Jun-19-15 A honeycomb-like structure able to withstand blunt impact repeatedly with superior protection could find its way to into vehicles, helmets and even military hardware.

The structure, called negative stiffness (NS) honeycomb, is more durable than current honeycomb technology—which can buckle and lose some of its protective properties after just one blow. In contrast, the NS honeycomb structures were created with a cell geometry that allows elastic buckling and enables the structures to “bounce back” and regain their energy-absorbing properties.

The structures can also be customized for different amounts of force by changing the cell dimensions.
