I don't know the specifics of the construction (fiber orientation) of that wheel but I doubt the failure was (primarily) a delamination. If delam was primary source of failure then I would say the design sucks -- I doubt that.
My guess is that one side of the wheel (compression side /up-side in photo) stayed intact enough to act as a hinge. Where as the opposite side had a sharp break (fibers) at the load focus. ...and with that big 'rubber-band' (tire) doing it's part, what's left is pulled closed again.
