Natural honeycomb structures occur in many different environments. Based on these, man-made honeycomb structures have been built with similar geometry to allow the reduction of the quantity of material used, and thereby realizing minimal weight and material cost.
Gallium arsenide is a type III/V semiconductor, with high electron mobility and a high saturated electron velocity compared to silicon,.
Metal foam is a cellular structure made up of a solid metal containing a large volume fraction of gas-filled pores. These pores can either be sealed (closed-cell foam), or they can be an interconnected network (open-cell foam).
Composite materials have been used in the marine industry for various applications including gratings, ducts, shafts, piping, hull shells, etc for several decades.
In the second instalment of AZoM's series on the applications of composites, we look at the increasing use of composite armour in military vehicles.
