Wouter,
Is that what think happened to this mast? That the walls warped and the section failed?
So if you are correct in saying
but rather because the masts enter into a instability failure mode. Buckling is one such example. The material should be able to handle the buckling loads quite well but the fact that it bends out of colom seriously lowers the stresses at which damage occurs
then I would recomment a sanding off the eglass and replacing it with one layer of 5.7oz weave carbon - it will resist both warping and bending failures much better.
