I don't believe nylon polymer is the wrong material for the application.
When new it is probably a lot better in flex than some sort of FRP.
Fourteen years just seems a really long time to have any sort of
plastic exposed to UV. Inspection of condition should include
a hand lens for checking and small cracks. There is a UV-resistant
nylon which is unfortunately black in color. Even lexan polycarbonate
windshields will deteriorate after 14 years in sunlight.
FRP will need to painted with UV-resistant primer for protection from
the sun also.
