As early as 1942, fiberglass and polyester airplane parts were being produced in the U.S. These were low pressure plastic laminates made from fiberglass cloth impregnated with resin. The first structural use of fiberglass in aircraft was in the cockpit of the first attempt at a combat helicopter feasible. These early aviation applications helped the industry experience the strength, light weight and durability of composite materials first hand. Composites continue to be used in today's most advanced commercial aircraft as airlines demand lighter planes for increased payload and reduced fuel use. Composite applications now range from flooring and cargo containers to fuselage and cabin components.
