information lead. As for the source, I may be able to help. It will
take me a few days to contact the buyers at Lockheed and get a reply,
but should result in several sources.
Food for thought: one might be able to epoxy 'paint' roving, Kevlar or
carbon fibre, onto the mandrel then wrap prepreg over it, then shrink
wrap, then cure. You could paint the unidirectional roving in any
direction or multiple directions. It would probably stop a battleship
without bending or breaking. A steel comb would spread the roving
strands in a nice even unidirectional layer prior to 'painting' in
place. Wonder if my dog Lucy's slicker brush would make a good steel
comb... hmmmm...

home built carbon fiber (CF) tubes. Mark Drela of MIT is a legendary
veteran of the Gossamer-series of human powered airplane campaigns. No
need for dissolving aluminum! Reuse your aluminum tubes as mandrels! He
gives advice on scantlings, attaching hardware, and more.
So does anyone have source for preimpregnated unidirectional carbon fiber?

P.S. Gossamer Odyssey is a great book, and one any home builder or
amateur aerodynamacist (with broad interests) should be able to relate to:
