Well in our aircraft we only use the aluminum honeycomb in fire-sensitive areas and structural areas(ie the galley, fax machine cabinets, base of cabinetry to attach to floor, etc) For general use it is mostly a fiberglas honeycomb, which is similar to the above mentioned, although it's considerably lighter and easier to work with. All the cabinet use this as a base, then get veneered afterwards. Carbon panels are use too, but mostly for floorboards. They get installed very much the same as the vanagon floorboards. I assume they are used b/c of their structural properties and also their resistance to fire, but I'd have to check that since I work mostly with the above mentioned composites. I assume commercial aircraft would be the same type of materials as the top end business jets, considering one of the major ways to cost savings of A/C operation these days is to reduce the weight, (les weight, less gas, etc) ...therefore the fiberglass could be used more often than an aluminum based honeycomb. By the way, here is a link to the inside of a Global Express for those interested... check the veneered cabinetry... http://www.raininair.com/interior_1.htm http://www.raininair.com/interior_2.htm http://www.raininair.com/interior_3.htm
