The Power in the Airframe...
The B777 is built with composite materials to improve resistance to damage, prevent corrosion and reduce aircraft weight.
But what are composite materials?
Composite materials are nothing other than layers or piles of high strength fibers in a mixture of a plastic resin. The high strength fibers are comprised of carbon and fiberglass. Basically, there are structures on the aircraft that are carbon fiber reinforced plastic. A plastic airplane is definitely lighter weight and more fuel efficient than its predecessor.
So what is made of plastic on the B777?
- Engine cowlings
- Strut fairings
- Nose gear doors
Want to win a beer question. Ask your B777 expert if they know what is made of plastic, and then can ask if they know what is made of fiberglass. Here you go on the fiberglass components:
- Leading and trailing edge panels
- Wing-to-body fairing
- Wing and main landing gear doors
- floor panels
The B777 is also more corrosion resistant because of improved draining features, corrosion resistant materials with better aluminum alloys, toughened carbon fibers, fiberglass floor panels, and improved finishes, with more primer and corrosion inhibiting compounds.
Boeing has come a long way from the Aluminum B727. More to come on this adventure...
