Ridged aluminium honeycomb
Aluminium honeycomb structures can take many different forms – from regular hexagons, to partially compressed diamonds, to elongated, reinforced shapes. Mimicking the geometry of natural honeycomb, these widely varied structures all have one common feature - an array of hollow cells between two thin vertical walls. The combination of strong side panels with light-weight honeycomb core, commonly referred to as sandwich construction, makes for a very solid form through the use of minimal material. With a high strength-to-weight ratio and minimal density honeycomb structures exhibit structural integrity as well as insulative qualities. By increasing the depth, such as this sample, one can increase structural strength along the shape’s Y plane, but if compressed along the X plane this shape will easily deform due to its thin walls. Aluminium honeycomb is widely used throughout aerospace applications (including aircraft and rockets), as well as within architectural applications. But it can also be found in everyday products like packaging material and cardboard.
