    Boeing 787 -- a sweet CF ride?

    Check it, fellow cyclists. Wonder if they'll have CF beverage carts and lavs on board?

    I wonder if it's going to cause any scarcity in materials that would raise the price of CF bikes.

    wow...plane using carbon fiber for fuselage? Maybe I shouldn't be so scared to put my fat butt on a CF bike after all.

    My uncle works for Boeing and was part of the design group (flight deck and exterior lighting) for the 787.

    Actually, Boeing has reportedly bought out all the spare and projected growth capacity in the carbon fiber industry for something like the next 5-10 years (it will take producers that long to catch up). This has driven the prices higher for companies that don't have fixed contracts.

    However, I think the amount of CF used in bikes is small enough the effect won't be very noticeable on new frames. More of the cost is related to the design and the manufacturing of complex shapes than the less than 2 pounds (plus epoxy) of CF.


    I don't know where all this "composites don't fatigue" crap is coming from. They do, but in a different manner than aluminum, and the directional nature of carbon fiber makes it a little easier to control.

    Yup. I`ll ride on an old crappy 737. Hats of to Boeing. But call me a nervous-nelly I hope the 787 doesn`t start disapearing from radar screens

    Yes, that's true, but they look good and go very very fast.

    Composite structures on aircraft make for some difficult trouble shooting regarding failure and fatigue. On the other hand, I have great confidence in the Boeing engineers. If it ain't Boeing, I ain't going!
    Flying a jet is no different than riding a bicycle. It's just a lot harder to put baseball cards in the spokes.

    I heard on the news this morning that Boeing have already sold 600 units and they haven't even had the first one in the air yet. If you order one today you'll get it around the year 2015.

    is there a group buy available?

    Hmmmmmmmmmmm,

    A plastic airplane might be good for Boeing and their stockholders, but I feel pretty sure that in the event of a failure like the one below, the plastic plane will just be a big debris field on the landscape below.

    Naturally this type of failure is not likely again because of engineering studies, but there might just be something the engineers didn't think about studying.

    Just sayin...........

    That failure was due to fatigue in the aluminium structure. Aluminium is unique in that it has no fatigue-limit below which it has infinite lifespan. ALL forces on aluminium will accumulate until a failure occurs. Steel, titanium, CF on the other hand, has a fatigue-limit where forces lower than this will allow the material to last indefinitely. CF has a fatigue limit close to its ultimate yield strength. So in a sense, it's hard to fatigue it without breaking it completely at the same time. For the same weight as aluminium, a CF plane will be much stronger with longer lifespan. Or for similar lifespan as aluminium, it can be lighter with higher performance.

    Oh wait.

    Heh. At least my frame is weld-less. I'd take looks over performance any day.
