Could not figure out a good way to word my search on the subject, so I came up empty handed.
My question, for those that might know, how do I convert the diameter and wall thickness of an aluminum tube, to the Dia and wall of a CF tube, if I want to maintain the same strength?
I assume that a cf tube of the same diameter and thickness of the aluminum tube would be significantly stronger.
For example, I have a 5/8" od aluminum tube with slightly more than 1/2 id.
What size CF tube would I need to have the same strength and stiffness?
For perspective: I'm working on an external frame pack design, and I want to start at a control before I start reducing the strength to save weight. I'd like to come up with a sub 2lb pack for normal loads up to 50lbs, then work on a sub 1lb pack for up to 20 or 30 lb loads.
