RE: [RCSE] Composite wingrods

[Walba, Rick]

I don't know what you're trying to accomplish but: Competition arrow shafts
are carbon over aluminum tubing. This produces the greatest stiffness per
pound and also some added toughness over conventional carbon shafts, as I
understand it.

I made a wingrod by filling a stainless tube with carbon filaments +
epoxy. It was not as good as a carbon rod, in the sense that a bending
moment that would not have broken a carbon rod did bend the composite rod.
