Did anyone try kevlar/carbon rod? Would hat be more resistant to breaking at the centre/plug end?
Wouldn't Dyneema/Carbon make more sense? Impact resistance can be double compared to 100% carbon. See the slide from a DSM presentation and here is the full document: https://mega.nz/#!WeZ0VYBD!X-_9i9PmW55C ... 5rnNG7800c

I happen to have 10 sq.m of DDCF005, 200gsm, T300/3K-SK99, which I don't need and can sell at cost.
Can provide also TDS and a copy of the DSM invoice on request. PM me if interested.

Is impact resistance an issue. So far my opinion is that it is not

Frankly, not my area of expertise. I saw some comments above on carbon bars breaking on impact with the cl/qr.
Another issue is making a composite tube vs buying a ready-made one :). Maybe just skinning a ready-made carbon tube with Dyneema/Carbon would be a more realistic option. An advantage I could see is if the tube cracks at either end (esp. while riding), the Dyneema should still keep the parts together and prevent complete loss of control over the kite.

Actually it can be. Carbon fibre alone will snap like glass and can cut hands up if over stressed. Blend it in with dynema, kevlar or innegra, especially on a sandwiched layer and it will likely still hang together. Also, the softer fibres are good as middle layers. Most stresses are over the internal and external skins of objects and thickening the distance between them is better done with a softer fabric as the hardness of carbon is wasted internally.

I designed some barend for my carbon bars out of hollow 3D-printend soft polyurethane, they fit in a 25x22.5mm carbon tube and come at €30.- a pair.

An adjustable-wodth carbon bar incl barends and leaders is €189.- (ex lines, trim, qr etc.)
