In today’s commercial aviation world‚ airlines have for a long time understood the importance of flying an aircraft as economically as possible. Advances in technology have made this possible in a number of ways‚ one of which is the introduction of composite material use wherever feasible. Composite materials typically offer a weight saving of between 20 and 25% when used in place of historically manufactured components made predominantly from alloyed metals. The heavier the aircraft‚ the more fuel
