Default epoxy failure by flexion?

Hi group,

If one were to sheath an unstayed, solid (grown) wooden mast with
unidirectional fibreglass and epoxy (painted over for UV
protection), would the sheathing eventually embrittle and fail? I'm
thinking that an unstayed mast goes through far more flexion cycles
and flexes much further than a stayed mast.

Thoughts?


Fiberglass and whatever over solid wood is not good.

Really?
