Hey Guys,
Its simple physical chemistry. FRP materials like fiberglass layups
have a property of softening at a specific temperature known as Tg.
Tg is sensitive to the particular temperature exposure history of that
piece of layup. If you heatsoak a part in an oven for a few hours at 175F
then the Tg will become about 175, up from the base Tg of Eglass/
Aeropoxy of about 150 or so (I dont have my ref materials here at work).
Colors other than white absorb more heat, no doubt about it.
If your bird is sitting at Kingman AZ, or Tucson, there is a good chance it
will droop on a summer day on the ramp. If you want to take chances,
well that why we call it experimental! I like safety margins where I can
have them.
