That can be arranged!
I totally understand your point about it braking completely vs plastic or alloy which might just bend etc. the kevlar will help with this, even if the carbon cracks the strands of kevlar will stay intact, the act as a sort of tether between the two cracked pieces. But yes, if it breaks it breaks and there is no bending it back in place.
In reality I'm much more confident in something I make from carbon/kevlar than aluminium but that has more to do with my metal working skills or lack their of...
