And, broken carbon (when I've destroyed scraps in the shop) tends to have a lot of needle-like shards - not something I'd like inside my kayak if I were getting thrashed.
Carbon can be stiff but brittle.
I agree that the transitions at the frames and joining tubes are a problem for a thin carbon tube.
Most aluminum has the happy property of getting a bit 'bent out of shape' before breaking.
It's probably not an issue, since 'ultra-light construction' and 'thrashed' don't really go well together.....
Same thread, different topic:
I've worked a bit with CF and 'glass sleeve material, and it is not easy to build hollow tubes using an internal mandrel.
You need a good polished mandrel, lots of mold release-type products, and the longer the tube the trickier it is.
So, if anybody is doing this with consistent success, please post here!
My last experiment in tube building needed to be slit lengthwise to get it free of the mandrel. Fortunately, it needed another layer of sleeve anyway, and wasn't a structural item.
