It may have been a defect. I have seen Aluminum frames crack under stress, mainly at the welds, which are a weakness in Aluminum frames. Composite is much stronger and lighter. I would take your bike to the shop and complain like hell, that really shouldn't have happened.

Is composites like fiber glass ? and does it fray like fiberglass ? or is it more of a solid consistency ?
I am sure Boeing will insure and take steps to make sure those airframe do not crack like that mountain bike did.
