Many moons ago, (early to mid-eighties), I was reading quite a bit of
material about the "new" composite airplane revolution and how different
life was going to be with the ability to make planes from the fantastic
substance. The main concern from the "experts" in many of these articles
was that they didn't know how the composite materials would hold up over
time. It seems that many folks thought that after years of sun exposure
and/or heat/freeze cycles, the materials might become brittle or degrade
in strength.

Now, obviously, I realize that there aren't many Long-EZ's falling out of
the sky and that many of the new methods are more advanced than the first
tries, but I was wondering how 25+ years has faired on these planes?
Was this fear just a crazy thought or was there some validity to the
concern that has reared its ugly head now that we've had some time to
look back?


You can get $20,000 for a glass glider built in the '70's.

Does that answer your question?

Yes, it now appears that composite gliders will outlast metal ones. The
gelcoat will degrade but the underlying structure seems to last forever.
