Should the Use of Composite Materials Be Prohibited in Critical Structures in Commercial Passenger Aircraft?
The use of composite materials in commercial aircraft is for one reason only – to save operating costs. The bottom line in this discussion is not how much money can be saved by composites. The true bottom line is the physical fact that composites fracture when they reach their limit, while metal usually bends before breaking. Boeing and Airbus are the only two viable commercial manufacturing companies designing and delivering passenger aircraft, and they are competing in every market and with every product line. They are in a race to develop the least heavy aircraft to carry the greatest weight the greatest distance for the least amount of fuel possible. If the Federal Aviation Administration and the National Transportation Safety Board should decide that, until such time as the composite structural design and manufacturing technology becomes sufficiently mature for all applications, composite materials could be prohibited for a common set of structures, including those most critical t
