Question about epoxy resin chemistry..

Me thinks the 'panels' are riveted on semi-cured because in the good ol' days when resins cured they were brittle. These
are simply skins on the wing and they are not adhered via the resin; the resin is supposed to be slightly green to allow
it to conform to the airfoil without cracking.

Lay out the panels on a big piece of glass and it will be pin hole free when you pull it off. The panel can be trimmed
to size while still on the glass. How many layers of what kind of glass are used in the lay-up? How sharp is the
tightest bend?


Wow. Big piece of glass. The skins will be a triangle with 8ft sides.
The plans specify two layers of 7.5 or 10oz glass. They extend up to
the 1" radius of the leading edge, but don't actually go around it.
