I've given this some thought and think it MIGHT be possible; BUT, you'd have to make your own rods due to the curvature issues that Phil pointed out. Also, most rods are actually TOO robust for what we are doing. I was thinking more like square Carbon tubes so that you still had significant area to bond to, and I completely agree with Phil -- you'd want some type of gusset at the joints. However, if you used square tube, I think you could bond them all rather than use a mechanical attachment. Where there is a will there is a way. I was thinking you could make the tubes, as a minimum, out of unidirectional tape wrapped in the 2 oz glass. Maybe 3/4 X 3/4 test that and see what it got you...


You likely have to make the curved ones over foam, then eat the foam out with something... Just a thought.

Nice work Phil and nice drawings Charlie.

I want to share a couple ideas.

1). Could you not make truss ribs out of pultruded graphlite rod. Just some simple pin jigs and use carbon fiber cloth at the joints?

2) I uploaded some photos that shows how I built some wing ribs. A full rack of ribs that really only took a few hours. The concept was to cut a slot and then drop in the spar. It all jig built and really pretty easy to do. Here's the link to our photo section.

Both of these ideas are for discussion purposes for CDII.
