Boeing’s 787 takes shape through innovative process
When it is unveiled in July of this year, the Boeing 787 Dreamliner will be the first of its kind – a major airliner made mostly of plastic. However, this isn’t conventional plastic; it is a sophisticated mix of carbon thread and epoxy resin, built into carbon-fiber tape and laid layer upon layer to form the fuselage, wings and tail of this new aircraft.
The various parts of the 787 are constructed all over the world, and when they come together for final assembly, the process is expected to take only three days because plastic parts can be constructed in larger sections than metal parts.
According to Boeing, there are multiple benefits to building an airplane from carbon composite materials rather than aluminum. One of the biggest appeals is the increased efficiency it offers. Since the plastic is lighter than aluminum, the 787 is expected to be 20 percent more fuel efficient than similarly-sized aluminum airplanes. In addition, since the carbon composite plastic does not corrode or fatigue as metal does, the 787 requires less frequent maintenance and can withstand a more humid cabin environment.
The increase in humidity, along with a number of other features, are examples of how this airplane’s design has put a strong emphasis on passenger comfort and convenience. Other highlighted features include more cabin space, larger windows, improved air and water purification techniques, and higher cabin pressure to improve the travel experience and help travelers feel less fatigued after their flight.
Boeing recently announced it has received more than 500 orders for the 787, which is scheduled to enter into service sometime in 2008.
