Why is the honeycomb structure not used in commercial aircraft?


Honeycomb structures are actually used often in commercial aircraft. The honeycomb structure is really strong since it does not buckle easily when bent, and it is lightweight since there are a lot of holes in the structure. This lightweight but strong property make it a perfect material to use on an airplane. It is most commonly used in the sandwich method of construction where it is sandwiched between 2 thin face sheets (commonly made of aluminum or carbon composite). This construction is stronger than just carbon composites, and it is light. Airplanes like the Boeing 787 Dreamliner use this construction in its wings, tail fins, and parts of the fuselage.
