  1. Boeing is building it's new plane, the dreamliner, with carbon fiber.
    The wings, fuselage. The cf must be consiberably more impact resistent than
    bike frames, or this would be suicide for Boeing. Hell of a note, if you
    looked out the window and saw the wing suddenly break off in some
    turbulence. Even though steel is real, I think Boeing skipped steel, and
    went straight to aluminum. Titanium, is too expensive and I think is only
    used in military planes. Boeing has sold a boat load of these dreamliners
    on contract already, but they still don't have a flying one yet. So if you
    fly a lot, you might have trouble finding a flight that isn't in a
    dreamliner when they start filling the skies.

    Don't count on that. Rumor I heard was that they can bend the
    prototype's wings so far above the fuselage that they almost touch.

    Simply incredible if true.

    why am i getting deja vu for all the bleating about cf forks all those
    years ago? and where are we now? "ubiquity" is the word.

    I somehow doubt that fifty years from now, carbon forks and
    Dreamliners will have displayed the longevity or earned the respect
    that 531 forks and DC-3s have over the last two or three
    generations.

    Sooner or later, people's CFRP forks are going to go the way of all
    plastic [censored], with the inevitable failures carrying more serious
    implications than the cracks in Chevrolet dashboards. And somebody--
    maybe the future equivalent of today's African airlines that fly old
    Soviet transports-- will figure out exactly how long it takes for the
    plastic binders in Boeing's CFRP to degrade. Heck, it could be
    American operators coping with the economic hardships yet to come.
    But I am sure that the relative difficulty of inspecting CFRP
    airframes will come home to roost in some way.

    The Airbus planes have been using CF for a while. In fact, the Nov
    2001 Long Island Airbus crash had carbon fiber failure due to
    excessive rudder input.

    I'm worried about what the increased atmospheric carbon content from all
    those Dreamliners flying around will do to global warming!

    And, steel IS real. My steel-framed bike is as real as anything else.
    It's natural, too. Unfortunately, though, it's not organic, but the paint
    on it partially is so I guess I can still sleep at night.

    Not a lot of aircraft anything is steel..Too heavy. Titanium in some
    tubing and some high temp areas. Aluminum and carbon is just a better
    choice. Airbus has had an aircraft with a composite tail and other
    flight surfaces for a long time. Same for military aircraft like the
    _F-18 series. Carpet fiber on aircraft is old news and Boeing sees a
    way to make these aircract light and strong and more
    efficient..something that needs to happen cuz fuel prices aren't going
    to come down anytime soon.

    What needs to be done is to replace the short range flights with
    high-speed rail. The high-speed rail would be more economically
    efficient (especially an inter-modal system that could replace most
    driving on freeways), have a lower environmental impact, and would avoid
    the need to wait in line for hours to be examined by TSA goons [1].

    [1] Not to mention the use of the "watch" and "no fly" lists as weapons
    to punish political opponents.

    The Airbus planes have been using CF for a while. In fact, the Nov
    2001 Long Island Airbus crash had carbon fiber failure due to
    excessive rudder input.

    The failure was not entirely due to the part being made of CFRP. American
    Airlines did a cheap repair on that plane installing a used rudder from a
    non FAA approved source outside the US (from France, I think). The rudder
    was not properly inspected prior to installation or during it's short
    usage before the unfortunate crash.

    http://www.globalaviationlaw.com/news_articles/2001/20011219_n.htm

    At the time of the crash the FAA only required visual inspection of the
    Airbus 300-600 rudders. After the accident a number of these planes were
    inspected with ultrasound and found to have hidden defects in the CFRP
    rudders.

    http://www.globalaviationlaw.com/news_articles/2001/20011210_lat.htm

    http://www.globalaviationlaw.com/news_articles/2001/20011119_nyt.htm

    I've been told by folks at Boeing that for every 1000 Lbs. removed from a
    commercial airliner there is a savings of $1 million during the plane's
    lifetime. This figure probably includes increased earning power because of
    more weight capacity.

    CFRP decreases the overall weight of the plane but probably shortens it's
    life expectancy.

    Similar planes, the Boeing 737 were designed for a 35 year life span. This
    plane was originally built for use in flights ranging up to 1500 miles.
    It's the number of landings that take the toll on aircraft life. These
    planes have been used mostly for short flights sometimes taking off and
    landing 10 times a day. This is why many airlines are switching to the
    smaller, cheaper regional jet liners.

    I flew round trip once on the shortest scheduled flight in the country -
    SFO to San Jose - 50 miles (AirCal). It was actually an SF to Burbank
    flight with a stop at San Jose. We flew down to San Jose, had a lunch
    meeting and flew back up to SFO on the next flight. I've also flown from
    SFO to Oakland - 11 miles.

    Those figures may be the before manufacture weight of the titanium. I'll
    check with one of my buddies who still does work with Boeing.

    The flap tracks and engine mounts are the largest parts made of titanium
    on an airliner.

    IIRC, it was CF which bankrupted Rolls-Royce in the 70's, trying to
    get it to work for turbine blades. The problem was it couldn't
    withstand bird strikes. Hopefully CF has got better or the birds have
    got worse since then....

    I qualified my statement as "rumor that I heard."

    Point is, I seriously doubt Boeing will be manufacturing airplanes that
    fall apart in turbulence (something that is ubiquitous in aviation).

    Then we can wait overnight on a train platform instead of an airport
    concourse. That'll be better.

    Or, as the CTA last week, sit in a 95-degree stopped train for an hour
    or two instead of waiting on the tarmac. I can see the improvement already!

    Dear Andrew,

    "Boeing has completed static testing of a three-quarter wingbox, but
    engineers are still considering whether to limit testing of the full
    wing to a 150% load limit held for 3 sec. of to continue bending it to
    see when it breaks. "There's a raging debate within the engineering
    team to see if we should break it or not," says [787 General Manager
    Mike] Bair."

    "Breaking it isn't necessary for certification, but Bair says the wing
    is so strong and flexible that there's been talk that maybe it could
    be bent far enough for the wingtips to touch above the fuselage—or
    come quite close."

    http://blog.wired.com/wiredscience/2007/06/the-new-boeing-.html

    Or just google for boeing + wings + bend + carbon and browse through
    132,000 hits.

    Will the plane come in nude natural carbon?
