I have about 10 experience of using carbon in racing yachts, not a direct comparison but I’ve formed my own views from experience of what works and what doesn’t and has broken (expensively).
Why would you use a product which was so sensitive to maintainence and setup ( unless you were a top end racer where weight was vital and durability less important) perhaps the OP didn’t put helitape in the correct place but if the result is a rapid wear in my book that means its the wrong material.
Secondly (re broken bars above) not all carbon is equal there are big differences in strength, resins, manufacturing quality (often laid up by hand so huge potential variance) IME far greater variance than with other materials like Aluminium.
@nimo – your bars certainly could be repaired, whether it’s cost effective to do so I don’t know.
