wink, wink;

got a plan to sneak wing mock up into work Autoclave when I can get away with it
I might be missing something about using prepreg but wouldn't putting it into the autoclave cause the 3dprinted interior to warp/melt and therefore cause the whole wing to warp whole curing the epoxy?

Prepreg cure temps are around 360 F.

The R&D lab @ work is 3-D printing with Titanium & Iconel.

Oh ok, I was thinking about the idea discussed earlier with printing the structure at home then laying carbon over top. A CF wing with titanium inner structure would be pretty cool.
